1. The Workshop on Population Data Analysis, Storage and Dissemination Technologies, funded by the United Nations Population Fund (UNFPA) under the project RAS/96/P12, was held in Bangkok from 27-30 March 2001. It was organized by the secretariat of the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) with active support of the Working Party on the Application of New Technology to Population Data.
2. The Workshop was attended by 38 participants from 20 selected countries in the Asian and Pacific region: Armenia, Bangladesh, Brunei Darussalam, Cambodia, China, India, Indonesia, Japan, Kiribati, Malaysia, Maldives, Mongolia, Nepal, Pakistan, Papua New Guinea, Philippines, Republic of Korea, Samoa, Sri Lanka, Thailand and Viet Nam.
3. The members of the Working Party, consisting of nine experts from Australia; Bangladesh; Indonesia; Japan; Macao, China; New Zealand; Philippines; Singapore and Thailand; and representatives of the Statistical Institute for Asia and the Pacific (SIAP), the UNFPA Country Technical Services Team in Bangkok, and the United Nations Statistics Division (UNSD) also participated as resource persons. Invited private sector companies also participated as observers and made presentations.
4. The list of participants is attached as Annex I.
5. The Workshop was inaugurated by Mr Kim Hak-Su, the Executive Secretary of ESCAP. He welcomed the participants and thanked UNFPA for funding the project, under which the Workshop was organized. He noted with appreciation that the collaboration between UNFPA and ESCAP would continue with a number of multi-year projects scheduled to start later in the year.
6. Thanking the resource persons, the Executive Secretary commended the role of the members of the ESCAP Working Party on Application of New Technology to Population Data in putting together the programme for the Workshop, and in delivering presentations and moderating discussions. Mr Kim also expressed his appreciation to the resource persons from the Australian Bureau of Statistics, the United States Census Bureau, the UNFPA Country Support Teams in Bangkok and Kathmandu, the United Nations Statistics Division and the Statistical Institute for Asia and the Pacific. Finally, he thanked the representatives from the private sector for their role in making demonstrations of state-of-the-art software applications for analysing and disseminating census data, which was in accordance with the Secretary-General’s Guidelines on Collaboration between the United Nations and the Business Community.
7. Noting the general importance of population censuses and surveys as a foundation for socio-economic statistics and for timely and targeted policy action by governments, the Executive Secretary encouraged the participants to make census data as easily available as possible to the clients, which goal could not be achieved without application of modern information technology.
8. Outlining some changes that the evolving information technology had caused at ESCAP, the Executive Secretary indicated that the main challenge for the secretariat was to mainstream the response to the development challenge created by information technology. The first step taken was to ensure that ESCAP’s programme planning always incorporated IT considerations when the technology could add value to the projects. The Executive Secretary informed the Workshop that larger programmes addressing sectoral and national IT development goals had been initiated. He also indicated that after the upcoming fifty-seventh session of the Commission, the secretariat intended to analyse whether any organizational adjustments might be warranted in order to respond more effectively to the challenges and opportunities that IT created in the region, particularly at the policy level.

12. The documents presented and presentations made at the Workshop are listed in Annex III to the report.
13. The evaluation questionnaire of the Workshop was completed by 37 participants.
14. On the basis of document STAT/WDT/3, the secretariat made a brief introduction to the project RAS/96/P12, “Application of New Technology in Population Data Collection, Processing, Dissemination and Presentation”, and its outputs. The document highlighted the significant role that the ESCAP Working Party on the Application of New Technology in Population Data had played in the implementation of the project activities, including the organization of two workshops and four technical expert meetings. The Workshop noted that the members had not only provided strategic and pragmatic guidance, but also themselves produced a large number of high-quality technical documents and guidelines on using selected new technologies in population census and survey operations.
15. The Workshop noted that the presentations, demonstrations, hands-on sessions with computers and the participants’ interaction during the sessions were expected to generate a set of recommendations, to be adopted at the end of the Workshop. The adopted recommendations are included in section VII of this report, starting from page 8.
16. The first day of the Workshop was dedicated to the sharing of recent experiences in the application of new information technology to the collection of population census data. Powerpoint presentations were made by the Working Party members from the National Statistical Office of the Philippines, the Statistics and Census Service of Macao, China, Statistics Indonesia and the Singapore Department of Statistics. In addition, there was a moderated session based on country papers that had been prepared by the participants.
17. The data capture strategy of the 2000 population and housing census in the Philippines was based on optical numeric recognition in four regional data capture centres, each having the following hardware: Windows NT network with five mid-volume scanners (Kodak 3510), fifteen Pentium III workstations, three magneto-optical disk drives, three CD-writers, a network printer and a 500 MHz Pentium III server with 90 GB hard disk capacity. The software components were Kodak MVCS for scanning, Eyes and Hands for Forms for ICR, and a tailor-made Census Progress Monitoring System. The four data capture centres were operated by a total of 146 persons, in two shifts, six days a week. A work shift was staffed by a shift supervisor, four data controllers (preparing forms for scanning and checking the validity of geographic codes), five scanner operators, four verifier operators and an operator for file preparation and transfer. In comparison, the staff required for capturing the data for the 1995 population and housing census had been more than 600 persons.
18. The Workshop noted that the recognition rate in the Philippines for OCR fields had been nearly perfect but that for handwritten fields, a much lower rate had been achieved, giving an average recognition rate of 90-95 per cent. Altogether over 15 million forms had been scanned and the average speeds for interpretation and verification were 3,400-3,500 and 270-320 forms per hour, respectively.
19. The Workshop heard that the Philippine configuration had too few (only four) software licences for data verification; 8-10 verification licences would have been optimal. Other problems included an uneven quality of the printed forms and illegible or too faint handwriting entries, which increased the work needed before scanning and at the verification stage. Some forms had to be enhanced or rewritten before scanning.
20. Encouraged by the overall success, the National Statistical Office of the Philippines had decided to use the ICR equipment and software again in the census on agriculture and fisheries; it was also considering using them in the processing of foreign trade documents.
21. The pilot project for the 2001 census in Macao, China, had also given very promising results. A client-server software of the OCR system had been developed in-house from the following components: Microsoft SQL Server 6.5, MS Access 97, Delphi 4.0 Enterprise Edition, ImageEN 1.6, and a dual recognition module consisting of a commercial API recognizer and an in-house developed neural network recognizer. The hardware included an image server, six document scanners and 24 Pentium workstations. The pilot runs had given an average recognition rate of 95.6 per cent, with error rate of 0.28 per cent. Within the reject rate (4.4 per cent), the confirmation rate and correction rates were 75.6 and 24.4 per cent, respectively. Compared to manual data entry, the Statistics and Census Service estimated that it would save 50 per cent in cost and that the time needed for data capture, validation and correction would be cut down from six months to one month.
22. The data capture of the Indonesian census, enumerated in June 2000, was decentralized to 41 centres, having a total of 79 scanners at their disposal. The 55 million double-sided household forms (representing the number of households in Indonesia) created a huge number of individual files during the capture process, which required robust file management features of the recognition software.
23. The Workshop noted that despite careful advance preparation, Statistics Indonesia encountered a number of problems in the recognition. The quality of the drop-out colour varied too much in the printed forms, and sometimes the guiding colour marks were not omitted as expected, requiring manual entry of the data. Like in the Philippines, optical mark recognition was nearly perfect while the recognition of numbers encountered problems caused by illegible or too faint handwriting and by the use of unapproved or dull pencils. The problems were partially caused by training the enumerators too far in advance; the inflexible regulations prevented use of the allocated training budget at an optimal point of time. The three-month gap between the training and enumeration had led to understandable memory lapses and ignorance of instructions; also a number of recruited enumerators had become unavailable in the meanwhile and had to be replaced by inadequately trained enumerators.
24. The Workshop heard that in Indonesia’s experience, human intervention by enhancing the quality of numbers did not markedly improve the recognition results. Besides, the manual editing process left rubber particles and other dirt on the forms, which increased the frequency with which the scanners needed cleaning.
25. The Workshop noted that in all three census offices (Philippines; Macao, China; and Indonesia), data were validated by using software to run predetermined logical tests. Tests were also run to detect systematic wrong recognition results, such as number 2 being recognized as 5, or number 0 incorrectly becoming 6 or 8.
26. The fourth presentation, by the Singapore Department of Statistics, was on its ground-breaking Internet census information submission, which was one of the three ways to collect census data in the Singapore Census 2000. The Workshop noted that the system, which was in the English language only, represented the second generation of Internet data collection systems in Singapore. (The first one, for the Business Expectation Survey, was launched in March 1998.) Of all Census respondents, 15 per cent chose to submit their information through the Internet while others responded either to computer-aided telephone interviews (CATI) or to person-to-person interviews.
27. The Workshop noted that the Internet data collection system had been designed keeping in mind nine target features, namely (i) fast performance, (ii) user-friendliness, (iii) security, (iv) stability, (v) compatibility with a large number of browser platforms, (vi) possibility to continue form completion in another user session, (vii) integration with other data collection modes, (viii) intelligent branching of questions, and (ix) verification during and after completion of the form. It further noted that given the existing technology, many of those requirements were in obvious contradiction with each other.
28. Based on prototyping and intensive user-acceptance testing, the front page of the Singapore Census site was made small in size (kilobytes) and the form was split into many parts in order to achieve satisfactory performance for users. For the same reason, the number of automated checks, which were first built into the form, had to be reduced and moved to the server side. Special attention was paid to the clarity of the form layout, questions and definitions. During the enumeration period, hotline telephone support was available, and in response to the feedback, frequent system upgrades were made. High-level security was maintained at all times, with escalation procedures and plans for contingencies in place.
29. Reviewing data capture technologies in the 2000 round of censuses in participating countries and areas, the Workshop noted that twelve of them relied on keyboard entry (Brunei Darussalam, Cambodia, Indonesia, Kiribati, Malaysia, Mongolia, Nepal, Papua New Guinea, Republic of Korea, Samoa, Sri Lanka, Viet Nam), two on OMR (Bangladesh and Pakistan), nine on OCR/ICR (Australia; Bangladesh; China; India; Indonesia; Macao, China; New Zealand; Philippines; and Thailand) and one on tri-modal capture (Singapore). Although technological challenges and problems still existed in using modern OCR/ICR, such as minimizing and detecting false positive recognition, the Workshop was pleased to note that with technological progress, the maturing technology had significantly lowered the total cost of census taking and improved the timeliness of the release of the results compared to the previous round of censuses.
30. The Workshop then made several recommendations regarding census data collection and capture (see page 9), including on
- the use of cell phones and emails to support data collection (paragraph 79)
- the establishment of a web site to provide information to census respondents (paragraph 80)
- the importance of careful questionnaire form design in successful character recognition (paragraph 81)
- just-in-time training of enumerators in filling out OCR/ICR forms (paragraph 82)
- the use of proper pencils or pens in filling marking OCR/ICR forms (paragraphs 83 and 84)
- the maintenance of scanners (paragraph 85)
- the robustness of the file management component of the data capture chain (paragraph 86)
- the testing of the proposed data capture configurations in real situations and making necessary modifications to them (paragraph 87)
- bandwidth, security and other considerations in Internet data collection systems (paragraph 88)
- the testing of Internet data collection forms in different bandwidths and improving the real and perceived performance (paragraph 89)
- data collection control when Internet collection was accompanied by other collection methods (paragraph 90)
31. Noting that data storage and data analysis had become increasingly closely related with each other because of technological innovations (such as data warehousing, data mining and the Internet), the Workshop decided to discuss them under one agenda item. A presentation “Setting up a statistical warehouse – salient points for consideration” was made by the Singapore Department of Statistics, which was currently in a process of analysing bids for the tender on development of a data warehouse. The presentation was followed by a discussion and sharing of regional experiences about data warehousing.
32. The Workshop noted that, compared to conventional data warehouses that were holding transaction and business data, statistical data warehouses had to facilitate more elaborate data analysis. In particular, statisticians required that data warehouses facilitated highly flexible data analysis, displayed metadata dynamically during analysis, and allowed the customization of reports and other outputs.
33. The Workshop noted that moving from a database model, where each census year formed a dedicated database with specialized codes and definitions, to a data warehouse consolidating data from censuses conducted at different times or combining census data with other data, was effectively facilitating increased use of census data. Setting up a data warehouse was a challenging process and involved a lot of preparatory work, including standardization of codes and definitions and cleaning of data.
34. The Workshop noted that a thin-client design, where most processing was done at the server-end, was preferred for warehouses that stored huge volumes of census data. In the system design, special attention had to be paid to the integration of data extraction and data analysis tools, since statistical analysis was often an iterative process, requiring testing of a large number of variables.
35. The Workshop noted that the Singapore Department of Statistics considered in its own evaluation that a hierarchical drilldown was a suitable method for selecting data, especially if business metadata was dynamically displayed. The ability to save previously selected items was very important for queries that were needed frequently or repeatedly. The Workshop noted that a “drag and drop” -type of interface made statistical analysis convenient: statistical parameters, such as the mean and standard deviation, could be calculated by ‘dropping them into’ data items (records or variables) or data items could be ‘dropped into’ statistical parameters. It also noted that the possibility to make revisions to data both locally (affecting only the analyst) and globally (affecting all users of the data warehouse) was a very useful feature.
36. The Workshop agreed that graphical and topographical tools, with integration to tabulation and drill-down possibility into points of interest in a graph or map, were desirable features in a census data warehouse. It emphasized that a good data warehouse system supported saving of data outputs, including data extracts, tabulations, analytical and other reports, or graphs, in common data formats which could be read by third party software.
37. In a discussion that followed, the Workshop noted that the practices of retaining census forms and stored electronic data varied in the region. Some census offices were legally bound to destroy census forms soon after data capture was completed. More often, however, census forms were stored for 10 years, or until the data of the next census was captured. The Workshop heard that in its 2001 census, Australia was going to make an exception to its stringent legal requirement to destroy census forms and records as soon as possible, by giving respondents a choice of having their names, addresses and census form information retained by the National Archives of Australia and released for research purposes after 99 years.
38. Noting that information presented on maps was useful at all stages of census operations and that geofererence databases were the core of GIS, the Workshop heard two presentations on GIS. The first one, based on document STAT/WDT/1, suggested a grid square database as a low cost alternative for presenting small area data. The Workshop noted that a grid square database could be considered by census organizations that did not have the resources and expertise required for digitizing the enumeration boundaries. Noting that the allocation of households to grid squares was resource consuming and required fairly detailed maps, the Workshop reviewed various techniques that could be used for allocating complete enumeration districts to grid squares.
39. In the second presentation, the Workshop was given an overview of how the United States Census Bureau used georeferenced data to display census results. The Workshop noted that the Bureau’s GIS system was building on its TIGER (Topologically Integrated Geographic Encoding and Referencing) database, which contained detailed geographic features for the United States. TIGER mapping was used at all stages of census, from enumeration to reporting of results.
40. The American FactFinder was a web-based system for access and dissemination of Census Bureau data on the Internet, built from TIGER boundaries and other geographic information, census data and metadata. The Workshop noted that the elaborate online system was a result of incremental work over the past two decades, responding to the legislative mandate to provide the public a full and free access to census statistics. In the FactFinder, it was possible to ‘drilldown’ the maps (which were based on vector graphics) from country-level down to the census block level. The Bureau also disseminated census information through printed atlases and tailor-made GIS products.
41. In addition, the Workshop reviewed GIS features of three CD-ROM products, described elsewhere in this report, by the Cambodian National Institute of Statistics (paragraph 59), the Statistics Bureau of Japan (paragraph 58), and the General Statistical Office of Viet Nam (paragraph 61)
42. The Workshop then made several recommendations regarding census data storage and analysis (see page 9), including on
- using new technologies to link census data longitudinally and with other data sets (paragraph 92)
- reviewing the applicability of data warehousing technology when new storage systems were considered (paragraph 93)
- starting the building of a data warehouse in a modular fashion and with manageable data content (paragraph 94) and with business and statistical considerations in mind (paragraph 95)
- the high cost and effort involved in setting up a data warehouse and cleaning the data (paragraph 96)
- building a central system for maintaining statistical metadata (paragraph 97)
43. It also made a few specific observations and recommendations on the use of geographical information systems (GIS) in data dissemination, including on
- starting the application of GIS from low-cost alternatives and moving to advanced GIS technology when skills improved (paragraph 101)
- considering grid square GIS as an alternative for presenting census data on maps (paragraph 98).
- the visually effective use of low-end GIS (Cambodian National Institute of Statistics) and high-end GIS (United States Census Bureau), see paragraphs 99 and 110.
44. The Workshop discussed the importance of building census data dissemination strategies on the users’ needs on the basis of three presentations, namely “Maintaining relevance in an environment of change” and “2001 census dissemination: a world wide web transition” by the Australian Bureau of Statistics, and “Responding to changes in users expectations” by Statistics New Zealand.
45. The Workshop observed that both countries were paying significant and continuous attention to soliciting feedback from the established and potential users of census data; often also independent evaluators were used. The results of user consultations were normally made public. The Workshop noted that in those two offices, user feedback formed a basis for a proactive product development strategy. Improved technology, government-wide policies and prior success of products were other key factors affecting their dissemination strategies.
46. During the development of census products, internal and external users were involved in prototype and acceptance testing. The Workshop noted that Australia and New Zealand routinely considered outsourcing as a possible alternative for product improvement and development.
47. Noting the experience of some participants that the audience in data users’ meetings remained largely unchanged over the years, the Workshop recommended that census offices diversify their strategies when approaching different user groups, such as the private sector, the public at large and children. Noting that the users’ awareness of available census products and services was just as important as good design, the Workshop recommended that census offices establish marketing strategies to inform established and potential users about the benefits of census products. Those strategies might use several modes of communication and include visible product launches. Maintaining ongoing awareness during and between the census cycles was also an important part of the strategy.
48. Observing that the participation of the private sector in user consultations was generally sporadic in the region, and in some countries absent altogether, the Workshop recommended that census offices make special efforts to contact potential clients in the private sector and involve them in producer-user consultations and other promotional activities as equal customers.
49. The Workshop noted that both Australia and New Zealand considered the web as the main dissemination channel for their 2001 censuses, focusing their development efforts accordingly. It warmly recommended that other census offices adopt a similar strategy as their delivery capability and users’ access infrastructure developed. It noted that using self-service and dynamic access to data, it was possible to make data users more self-reliant and lower the overall dissemination cost. The Workshop observed that modern information technology was also changing the role of printed material: while some of the ‘traditional’ publications were being phased out in Australia and New Zealand, efforts were made to develop a capability to print any electronic publication, on an individual basis, as and when needed.
50. The Workshop noted that both Australia and New Zealand were planning to continue to publish community profiles of key census data as those products had been effective in raising public awareness of census data and in increasing its use.
51. The Workshop noted that the Internet significantly shortened the delivery time of census data to users; the technology also improved the predictability of data release as the printing process and distribution often took a longer time than expected.
52. The Workshop then made several recommendations on general implications arising from the need to take data users’ needs into account in dissemination strategies and technologies (starting from page 10). It recommended that statistical and census offices
- adopt a proactive strategy towards the improvement of data dissemination (paragraph 102)
- diversify data dissemination strategies and technology solutions according to the needs of different types of users (paragraph 103)
- utilize the possibility offered by optical recognition to capture and release census data gradually, starting from key information (paragraph 104)
- use prototyping and vigorous testing to perfect dissemination products (paragraph 105)
- use modern marketing techniques to increase data use (paragraph 106)
- choose hardware and software platforms that are compatible with standard technologies (paragraph 107)
- provide web links to national counterpart sites and other sites containing useful census information (paragraph 108)
- consider creating community profiles of census data to increase its use (paragraph 109)
54. From the users’ point of view, the Workshop saw modern information technology as a means of breaking down the barrier to accessing census data. The technology brought users large volumes of data more easily and cheaply and allowed the creation of systems where users could service themselves. The ultimate goal, which was well within the reach of currently available technology, was that all publishable census data was made available on the Internet. A significant advantage of that dissemination strategy was that the same facility could cater for the needs of both internal and external users.
55. The Workshop recognized that general data users, such as students, pensioners, libraries, and small businesses normally required relatively simple sets of data for one-time use. However, all those uses covered a large range of information. Analysts, on the other hand, had complex and often voluminous requirements, with detailed regional and other breakdowns; they were also interested in detailed metadata. The Workshop acknowledged that development of a web site catering for all those needs was challenging; that task was not made easier by the requirement of delivering acceptable response to user front-ends at all times.
56. The Workshop noted that Statistics New Zealand was planning to expand the use of intermediaries in connection with its 2001 census, including the media, libraries, information brokers and bundlers, channel managers of high speed networks, community organizations and government organizations who already had close contacts with user groups. That office was also planning to significantly improve the navigation of their census web site and pay special attention to the users’ ability to service themselves. That was achieved, among other things, by using common language; removing or explaining census jargon; increasing the ways to access data, terminology, area breakdowns and maps; and by improving sorting-by-topic and other features of the search facility.
57. The Workshop agreed that considering the cost savings and benefits the application of present-day technology brought to census taking, processing and data dissemination, the expenditure on information technology was relatively easy to justify.
60. The Workshop was especially impressed by the visual effectiveness and user friendliness of the PopMap-based product. The application consisted of detailed maps for Cambodia, its provinces, districts and communes, with line layers for the main routes and rivers and point layers for the villages and schools. A total of 123 different indicators down to the commune level formed the heart of the application.
61. The General Statistical Office of Viet Nam demonstrated a CD-ROM containing a three per cent sample of the 1999 census. The application was based on the IMPS (Integrated Microcomputer Processing System) suite, including its database, cross tabulation, and table and map viewer components. In that connection, the Workshop noted that IMPS was the main data processing tool for censuses in several statistical offices in Asia and the Pacific. Its popularity was due to its low cost (acquisition free) and the possibility to use it flexibly, either as a complete processing system or any of its data entry, data editing, tabulation, data dissemination, statistical analysis and data capture control modules individually.
62. The Workshop noted that IMPS was being replaced by the Census and Survey Processing System (CSPro), which was an integrated public domain software package for entering, tabulating and mapping census and survey data, featuring the user-friendliness of IMPS and the computational power of the Integrated System for Survey Analysis (ISSA).
63. The Workshop also reviewed three commercial data dissemination tools suitable for small and large data sets, and having powerful desktop data manipulation facilities and web based detailed data access facilities. PC-Axis was a product developed in collaboration with many statistical organizations in Europe and Africa, with Statistics Sweden as the main initiator and coordinator. Beyond 20/20, by a Canadian company with the same name, was a comprehensive tool for analysing and sharing statistical data, while SuperSTAR was a powerful tabulation tool for aggregating, viewing and presenting multidimensional data, developed by Australian Space-Time Research. The Workshop reviewed some web sites, as well as data dissemination CDs, delivering data in the three formats.
64. The Workshop observed that the performance, especially in terms of retrieval and tabulation speeds, and the flexibility and ease of control of the demonstrated commercial software went well beyond what off-the-shelf database packages and some of the public domain packages provided. Without ranking the demonstrated commercial tools, the Workshop recommended that statistical and census offices consider evaluating them when creating dissemination strategies. It noted, however, that the sophistication carried a price tag and that the prices for census offices were subject to one-to-one negotiation. Among other factors, the prices depended on the population of the country, the size of data sets involved, and the volume of dissemination.
65. The final presentation at the Workshop, by the Interregional Adviser on Computers and Informatics of the United Nations Statistics Division, was based on the learning experiences of Statistics Sweden in keeping up with increasing traffic to its web site. When Statistics Sweden was releasing its annual population figures on the web at the end of 1999, its server soon became inaccessible due to the unprecedented surge in the number of requests. The Workshop noted that to prevent similar embarrassing breaks in service in the future, the agency had taken several swift actions. It changed the most popular data content to relatively small static HTML pages; increased the server’s bandwidth to the Internet; added a second web server; upgraded the server operating systems from Microsoft Windows NT to Windows 2000; used software to automatically balance the load between the servers; and rerouted email elsewhere to avoid large files taking up bandwidth from the web service. It also included a direct link from its home page to the most wanted population tables for easier and faster navigation.
66. The Workshop noted that after the incident Statistics Sweden had substantially upgraded its staff development programme to improve technical skills and organizational coordination in content preparation. More attention was being paid also to the monitoring of the web site traffic, including the popularity of pages, and to periodic test runs under heavy external load.
67. The Workshop noted that traffic monitoring was also a necessary security measure. Hostile attacks to the web server were best countered by mainstream firewalls that were kept up to date. The Workshop agreed that security technology had to complemented by a contingency plan that allowed a quick recovery of service and minimized the escalation of damage.
68. The Workshop noted that the interruption of web service because of heavy peak traffic was not uncommon. For instance, the Australian Bureau of Statistics had once been forced to close down its web server as the demand for national accounts figures jammed its capability to deliver. The corrective measures taken were very similar to those adopted in Sweden.
69. At the end of the Workshop, several participants demonstrated their live web sites and invited the audience to visit their census pages. The URLs of the offices of the participants and resource persons are included in Annex I (List of participants).
70. On data dissemination through the Internet, the Workshop recommended that statistical and census offices
- adopt the Internet as part of their dissemination strategy, use hypertext interface on CD-ROM, and use email for data promotion and for disseminating summary results (paragraph 111)
- develop an internal policy and utilization of the Internet in general and include the production of web material in training programmes (paragraph 112)
- create functional coordinating mechanisms for web site management (paragraph 113)
- improve internal web site management skills through recruitment and training (paragraph 114)
- design census dissemination sites for relatively low bandwidths by using various page authoring and data access techniques (paragraph 115)
- provide file formats and scripts that all common browsers could handle (paragraph 116)
- include in web sites census metadata in an easily accessible format (paragraph 117)
- consider features that helped clients service themselves when accessing census data (paragraph 118)
- monitor the web site traffic and adjust the site content and navigation as the reports might suggest (paragraph 119)
- pay special attention to the clarity of information and test the individual pages and the whole site thoroughly (paragraph 120)
- provide the most popular content in static HTML in order to improve the site performance (paragraph 121)
- be prepared to adjust the number of servers and balance the load as the traffic increases (paragraph 122)
- to ensure the uptime of the public web site, use separate servers for resource-consuming tasks (paragraph 123)
- keep production servers isolated from the Internet (paragraph 124)
- consider using XML to code structured data pages (paragraph 125)
71. The Workshop adopted the following conclusions and recommendations.
72. The Workshop reviewed the recommendations of the previous workshop (Workshop on Application of New Information Technology to Population Data, 12-20 October 1999), noted that they were still valid and requested that the secretariat, in due course, merge them into the recommendations of this workshop.
73. The Workshop noted that the utilization of IT had brought considerable quantifiable benefits to census processing, especially in the form of direct cost savings and improved timeliness of statistics. It recommended that statistical and census offices continuously accumulate experiences in evaluating, developing and using information technology, as the development of organizational practices and of the skills required to manage information technology effectively was a long process.
74. Noting that maintenance of the privacy and confidentiality of data providers was very important, the Workshop recommended a very cautious approach towards outsourcing of census data collection and data capture operations. For the same reason, the release of unit record data and the dissemination of small area statistics had to be subjected to careful confidentialization. The Workshop noted, however, that similar concerns were not generally involved in the dissemination of census statistics and recommended that census organizations consider the possibility of outsourcing the development and marketing of census products, in order to make them more attractive to paying customers and other users.
75. The Workshop recommended that statistical and census offices continue to share information about their application development with other government departments and foreign counterparts. It requested that the secretariat facilitate such exchange in the region.
76. The Workshop recommended that before initiating extensive in-house development or procuring expensive software and applications from outside, statistical and census offices evaluate available public domain software and the possibilities of creating applications by customizing common off-the-shelf packages and office suites.
77. When an Internet application did not support all browsers, the Workshop recommended that information be supplied on which browsers were supported and for which versions and screen resolutions the site was optimized.
91. The Workshop recommended that statistical and census offices establish a hotline and other support services to coincide with the introduction of an Internet data collection application.
99. The Workshop compared with interest effective illustrations of census data by using “low-end” and “high-end” GIS technologies. The United States Census Bureau had been developing its GIS system in an incremental fashion for more than two decades and was now using very elaborate GIS features on its public web site disseminating the results of the 2000 census.
100. The geographic presentation component on a CD-ROM containing the results from the 1998 census of Cambodia, which had been created by using PopMap, a free software package developed by the United Nations, was also visually very effective.
