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

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.

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)

Regional Summaries According to the
Questionnaire:
Special methods for the delineation of enumeration areas:
Kenya
• The delineation of EAs for the 2009 census is being done
in-house
• 20 % of the country has been covered; 5 % of the slums
covered
• one provincial region out of 8 has been covered.
• Significant improvement in the quality of maps for these
currently mapped areas

Regional Summaries According to the
Questionnaire:

EA’s were delineated based on number of households where each EA
constituted approximately between 80-120 households for urban areas
Exceptions were made when distances were greater than or equal to 15
or more kilometres between localities in sparsely populated areas
In such cases, although the population was not up to 80 households, an
EA was demarcated to consider travelling time for enumerators
Base maps of scales between 5000-25,000 were used in the urban
areas while scales of 50,000 was used in the rural areas, covering the
entire country from regions, districts, sections and EA’s
Having precise EA delineation greatly improved the quality of data
collected
