UN Regional Seminar on Census Data Dissemination and Spatial Analysis
5-8 October, 2010 Bangkok, Thailand
Outline
• Introduction to Population and Housing Census
• GIS for Census data dissemination
• NSO-GIS System of web map service
• Constraint in developing NSO-GIS
Introduction to Population and Housing
Census
 Conducted every 10 yrs. in the year ending 0
 New round of census is conducted in this year (2010)
and now enumerators are collecting census data (Sep-Oct)
 Data collection method :

back again to pick up)
Personnel : 71,000 (9,000 supervisors , 62,000 enumerators)
The 2010 Population and Housing Census
Data Dissemination
 Press release
 Publication Report:
 Preliminary ; 3 months
 Advance
after completion of
field work
; 6 months
 Final ; 2011 (province and whole kingdom)
 Special analysis report
 Thematic map report
 Web-based data dissemination
Census website at URL
http://popcensus.nso.go.th
as a mean of census information and data
dissemination via internet in which various products of
Census results are put on web for viewing ,downloading or
printing out such as report , quick tables , quick statistics
/indicators
 Data warehouse for interactive tabulating data.
 NSO-GIS system for interactive thematic maps
display .
Census Info put on web and CD-ROM
 Micro data ( only 1 % will be released )
Customized data requests as well
GIS for census data dissemination

There are 2 map services on line :
1.NSO-GIS
is Statistical Geographic Information
System which use GIS and web map /web feature
service of OGC standard technology for census and
survey data dissemination by thematic map. The
Interactive Thematic maps can be selected to display at
region level down to sub district level.

2. Census Info
adapted from DevInfo
technology as well as TPD Info which
address adhoc issues ,ie., MDG , poverty
(Table , Graph and Map ).
NSO-GIS (Statistical Geographic Information System )
 NSO-GIS was developed in 2009 by outsourcing
 Selected 17 census/survey projects with 197 core
indicators were designed for producing web based
thematic maps
 NSO-GIS web map service was launched on 1 July 2009
 Census and survey data base as well as thematic maps are
updated regularly

2010 Census Map in NSO-GIS
1.GIS web map service at
http://sgis.nso.go.th
 Preliminary result : Feb. 2011(after
finishing data processing 2 months )
 Final result : 2012 (after finishing data
processing 4-5 months)
2. Thematic map report
2010 Census Map in NSO-GIS
Most indicators are the same as 2000 Census
 Population : No. of population, Non Thai
population , Density of population , % of pop. in
municipal area, growth rate
 Demographic and social characteristics :
% of pop. by age group, nationality, religion,
marital status, education , occupation ,sex ratio,
literacy rate , migration rate, fertility ,etc.

Constraint of developing NSO-GIS
1. The personnel in charged of GIS for data
presentation are statistician so they lack of
skill in Thematic mapping and GIS web
based administration .
2. Lack of knowledge on GIS,ICT technology ,
spatial analysis techniques as well as
experience in applying GIS with statistical
work.
