Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago,
22–26 Oct 2007
Key Responses to Section on Institutional and
Organizational Aspects (Part B)
•
Almost all NSOs 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:
•
•
•
•
•
•
Collect 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
Update 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
Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago,
22–26 Oct 2007
Key Responses to Section on Institutional and
Organizational Aspects (Part B)
•
•
•
•
Close to all census mapping agencies collaborate
regularly/occasionally with other departments & other
NSOs 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 NSOs 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.

Key Responses to Section on Mapping Activities
(Part C)
•
Currently, most NSOs are heavily engaged census mapping
projects/activities
•
Most are integrating (or plan to integrate) new methods and

22–26 Oct 2007
Special methods for the delineation of enumeration areas
(Part F):
Bahamas
• Scale of coverage was at the dwelling unit level
• EA delineation conducted based on the natural geographical
division of the country (islands) and then the political divisions
of the islands into constituencies.
• Constituencies were used as supervisory districts and further
delineated into EA districts of ~100 households.
• Delineation at the settlement level was done for all islands
(except New Providence and Grand Bahamas, where political
constituencies were used)
Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago,
22–26 Oct 2007
Special methods for the delineation of enumeration areas
(Part F):
Belize
• All ED data was produced manually on hardcopy maps.
• EDs were chosen based on the number of households.
Grenada
• Based on subdividing existing boundaries through parishes, a
grouping of approximately 125 households was deemed
manageable for an enumerator to canvass
Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago,
22–26 Oct 2007
Special methods for the delineation of enumeration areas
(Part F):
Trinidad and Tobago
• The CSO developed the delineation of EDs from the 1960 Census
using 150-200 households as a proper Census workload
• These have since been updated, re-coded and subdivided over
the years to accommodate a workload less than 200 households,
and 100 households in squatting and terrain areas
• Work is progressing at a Community level on urban/rural
classification at an ED level
• ED maps are drawn to graphical scale to accommodate 11’x17’
photocopying size
