Key Responses to Section on Institutional and Organizational Aspects (Part B)
• Almost all NSO’s have a special unit responsible for census mapping with staffing ranging from 10’s to 100’s.
• The main tasks of the census mapping unit/division) are the following:• Collecting data from various census and surveys to generate tables at
different administrative levels.• Develop a database of information (not limited to census and surveys)
that can be geographically referenced.• Prepare base maps and EA maps for censuses and surveys• Updating base maps and GIS information• Provide geographic information on enumeration areas for censuses
and surveys• Prepare and publish updated maps which include thematic and
statistical maps

Key Responses to Section on Institutional and Organizational Aspects (Part B)
• Close to all census mapping agencies collaborate regularly/occasionally with other departments & other NS offices or divisions within the NSO.
• Just over 50% of countries have statistical laws or laws governing the statistical production that explicitly deal with the production and/or dissemination of census data and/or maps.
• Many NSO’s have groups of national users of census maps and spatial data such as private and public institutions to help identify core issues and data needs of users
• More than half the country respondents have a National Spatial Data Infrastructure with several others proposed or in-the-works.
Workshop on Census Cartography and Management, Bangkok, Thailand, 15–19 October 2007

• Most are integrating (or plan to)new methods and technologies into census mapping activities
• More than half are currently producing base maps for census mapping activities
• Scales range largely from 1:1000 to 1:1,000,000 depending on the application (Country level, district level etc.)

and associated attribute attribute data• Using new technologies for census mapping operations• Preparing maps and databases for the operation of the census• Educating the NSO office of the importance of geographic data and
information• Acquiring better resolution imagery & increased GPS accuracy for
mapping operations• Improving training/recruiting staff in GIS & census mapping

• To facilitate better decision-making.
• Increased request by data users.

Special methods for the delineation of enumeration areas:
• Largely In-House with some outsourcing
• Delineation of Enumeration Area commonly conducted at the urban scale at the moment
• Scales for Enumeration Areas vary, with common ranges from 1:500 to 1:25,000 for urban and 1:10,000 to 1:50,000 (vary by case)

Workshop on Census Cartography and Management, Bangkok, Thailand, 15–19 October 2007
Regional Summaries According to the Questionnaire:
Special methods for the delineation of enumeration areas:
Bhutan• Rule framed in the mapping manual for the surveyors- each EA consists of
max. 40 households/structures urban and 25 rural
• GPS coordinates taken for 25 households- surveyor delineates EA following the topographical features (rivers, footpath, etc.)
• If no physical features for delineation exist, imaginary line used.
• The EA maps have a title; Block Name; EA #; structure #; numbering is serially for particular blocks only
Workshop on Census Cartography and Management, Bangkok, Thailand, 15–19 October 2007
Special methods for the delineation of enumeration areas:
Malaysia• EA’s are restricted to the preferred range of 80-120 living quarters
or 500-600 people and do not to cross any administrative/local authority areas
Pakistan• Delimitation of EAs are carried out with the collaboration of
Provincial Revenue, Local Government & Education Departments • Each enumerator is assigned an identifiable area comprising 150 to
200 houses
Regional Summaries According to the Questionnaire:
Workshop on Census Cartography and Management, Bangkok, Thailand, 15–19 October 2007
Special methods for the delineation of enumeration areas:
Philippines• Delineation is conducted based on the following criteria:

• Estimated number of days to complete the enumeration of the EA exceeds 25 days; or
• Terrain, physical arrangement of households (scattered or clustered), and the distance of one household to another are expected to hamper the timely completion of the enumeration.
