This paper discusses the applications of IT in different stages of the 2006 Population By-census (06BC) in four broad areas:

(i) supporting field operation with Geographic Information System (GIS) technology;
(ii) allowing sampled households to make appointment for enumeration at preferred time slots through a Internet application “Appointment Request Service”;
(iii) providing electronic questionnaires to respondents for electronic reporting; and (iv) using Intelligent Character Recognition (ICR) and Optical Mark Recognition (OMR) technologies to capture data on completed questionnaires.

Paper presented at the 23rd Population Census Conference "Utilization of the 2000 and 2005 Rounds of Asia-Pacific Censuses" in Christchurch, New Zealand, 16-18 April 2007.
