National Statistical Office
1. Historical background
Official statistics in Thailand began on April 1, 1915 under a decree by His Majesty King Mongkut (Rama VI). An office, named the "Statistical Forecast Bureau", was established as a department under the Ministry of the Royal Treasury. His Highness Prince Bhittayalongkorn was the first Director General. The department underwent several changes in status until it became the National Statistical Office (NSO) in the Office of the Prime Minister on May 23, 1963. Subsequently it has expanded its network to all the regions with a provincial statistical office in each province.
In 1992 a royal decree was proclaimed, dividing the NSO into 9 divisions, each of which had specific authority and functions. Later in 1993, another change took place and the administration of the NSO was divided into central and local administrations. The organization has remained so until the present time.
2. The organization of the National Statistical Office (NSO)
At present, Thailand has a decentralized statistical system. The NSO is the core body that collects basic statistical data while other agencies in various ministries and departments also issue there own statistical data which mostly used for their internal affairs.
The organization of the NSO is divided into the central and the local administrations.
2.1 The central administration
The central administration comprises 9 divisions as follows:
1) The Office of the Secretary deals with all office correspondence, administrative coordination, public relations, finance, accounting, office supply and personnel administration.
2) The Statistical Data Bank and Information Dissemination Division is responsible for the compilation of statistical data produced by other statistical agencies, and the preparation of statistical publications. The division also provides statistical data and information to users in and outside Thailand, exchanges statistical data as well as disseminates the survey/census reports and statistical publications with local agencies and international institutions.
3) The Field Operations Division is responsible for planning of field operation and collecting the data of the censuses and surveys in Bangkok Metropolis.

9) The Social Statistics Division is responsible for conducting censuses and surveys on social issues, performing statistical analysis on social data, preparing the census and survey reports and producing social indicators.
2.2 The local administration
The local administration consists of 75 provincial statistical offices. These offices are responsible for the field operation of the surveys and censuses conducted by the NSO. They also act as provincial statistical information centers, promote and disseminate statistical information and provide consultation regarding statistical work for the government agencies in the province.
3. The workforce
At present, 1,064 civil servants and 83 permanent employees work in the NSO. Of this number, 654 work in the central office and 493 work in the provincial offices. Apart from this, 1,114 temporary employees are hired to help in collecting and processing the data. Of these, 456 work in the central office and 658 in the provincial offices.
4. Duties of the NSO
The NSO is governed by the 1965 Statistics Act to perform the functions which can be classified into five distinctive categories as follows:
4.1 Statistical data production
The statistical data production is considered the most crucial duty of the NSO and only basic statistics on the social and economic are produced.
Economic statistics: agriculture, marine fishery, industry, business trade and services, household income and expenditure, transport and communication, etc.
Social statistics: population, labour force, migration, education, health and welfare, culture, housing, etc.
Two important methods used in data collection are census and survey. The NSO produces timely statistics of good quality based on international statistical standards. In addition, new statistical techniques are constantly being studied and developed so that the NSO can produce higher-quality statistical data. The data, once analyzed, are prepared in the form of reports for dissemination.
4.2 Statistical data dissemination
The NSO is the statistical information center for the whole country while provincial statistical offices also exist and act as information centers for the provinces. Data available in the centers consist not only of data produced by the NSO but that produced by other government agencies as well.
The information is available in the forms of publications such as census and survey reports, quarterly statistical bulletins, statistical year books, or in electronic media such as diskettes, CD-ROMs, and internet at NSO's website: http://www.nso.go.th.
The NSO also provides Statistical Information Searching System (SISS) for individual searches at the NSO.
In cases where required statistical data are not available, the NSO may consider special tabulation for the users. The NSO's major users include the Office of the National Economic and Social Development Board, the Ministry of Labour and Social Welfare, the Ministry of Public Health, the Ministry of Agriculture and Cooperatives, the Bank of Thailand and international organizations such as World Bank, IMF, ILO, ADB, ESCAP, JICA, MITI, etc.
4.4 Statistical technical advice and consultation
The NSO provides technical advice and consultation to other government agencies and private sectors on statistical methodologies, sampling design, questionnaire design, estimation of statistical measures, data analysis and report preparation to ensure that the preparation of each agency’s statistical data is of a high quality in compliance with recognized statistical standards. This helps promote and develop the national statistical system of Thailand as a whole.
4.5 Statistical and computer training
The NSO regularly organizes several in-service training programs for the staff of the NSO and those of other government agencies. The training aims to increase knowledge, skills and experience relating to statistics to those working in statistics fields.
Several in-service training courses are offered by the NSO as follows:
- The statistical training program emphasizes principles of statistical methods, data collection procedure and practical training. The trainees are required to work on one survey project in which they have to be involved in every stage of a statistical survey operation.
- The training program for NSO officials in both the central and the provincial offices aims at developing their experience and skills.
- The computer application training program is offered to government officials as specified in the cabinet’s resolution.
- Other training programs are offered to statistical personnel from overseas.
5. Communication with users.
Eventhough, we do not have a users council, the NSO has close communication with its users especially the National Economic and Social Development Board, our major user, which is responsible for formulating and implementing national economic and social development plans.
To serve users' need and make its products more useful, the NSO occasionally organized meeting/seminar on statistical data required for decision making. The meeting/seminar were attended by users and other statistical producers. Also, in planning for surveys and censuses, other government agencies concerned were invited to send representatives to be members in the Steering Committee and the Working group.
6. Data dissemination
The statistical information services provided by the NSO consists of data compiled through the NSO censuses/surveys and data produced by other statistical government agencies.
The NSO disseminates statistical information to the users through various ways such as publications, diskettes, magnetic tapes, special tabulation, etc. The NSO has also organized a system for users self service by computer. In case of providing data through diskettes, tapes, and special tabulation upon private requests, the expense for computer processing is to be paid by the users.
In terms of statistical data disseminations, fair information practices are used. The NSO maintains the confidentiality of individual responses. Confidentiality of the information that respondents furnish is assured by combining the data reported, and publishing the findings in summary tables, analyses, and reports. Data of less than 3 establishments is not to be issued.
In addition, according to the Statistical Act B.E. 2508, the person performing his/her duties disclose individual information shall be liable to imprisonment or a fine.
7. Publications
In general, our publications (mostly are reports on surveys/censuses) are distributed to local and foreign government agencies including international organizations upon request, private sectors are subject to pay at market prices.
8. Information services
In providing users with better statistical information services, the NSO had developed electronic data dissemination using the World Wide Web as the medium of distribution. This medium is commonly known as the NSO Web-Site (www.nso.go.th). The NSO has also provided data to meet the Special Data Dissemination Standard (SDDS) required by the International Monetary Fund and subscribed to by the Government of Thailand.
An initiative o f the National Statistical Office to develop a statistical data warehouse, which will enable internet access to microdata, macrodata and metadata, is underway. This will provide clients with direct and user-friendly access to all offcial statistics produced in Thailand.
The NSO provincial statistical offices have also developed their own web sites. Hosted at NSO headquarters and accessible through the national web site, the provincial web sites are developed and maintained by provincial staff.
9. Statistical Training Programme
Concerning training, the NSO regularly organizes several in service training courses for the staff of government agencies, state enterprises, and of the NSO itself. The main objectives of the training are to develop experience and skills of statistical personnel and to promote their coordination on statistical activities as well. Other than two courses in statistics (primary and intermediate) emphasizing on the theoretical statistics and its application for practical works, various courses in computer data processing are also offered. In addition, the NSO in collaboration with the Statistical Institute for Asia and Pacific (SIAP) had organized, from time to time, sub-regional courses on statistics for regional statisticians
