1. Workshop on Census Cartography and Management - October 2007 Dissemination with GIS United Nations Statistics Division

2. Workshop on Census Cartography and Management - October 2007 Census dissemination  A census is not complete until the information collected is made available to potential users in a form suited to their needs  The information may be: included in published tables and reports for general distribution produced as tables in unpublished form for limited distribution stored in a database and supplied upon request, or disseminated online (in this case it will be available only to connected populations)

3. Workshop on Census Cartography and Management - October 2007 Census geographical units  The census provides information at any geographical level, pre-existing or user defined

4. Workshop on Census Cartography and Management - October 2007 The power of maps  Maps visually communicate a concept or an idea.  Maps are often meant to support textual information  Maps appeal to the viewer’s curiosity  Maps summarize large amounts of information concisely  Maps can be used for description, exploration, confirmation, tabulation  Maps encourage comparisons: Between different areas on the same map: where are population densities highest? Between different maps: is child mortality higher in the districts of province A than in province B? Same area: where and by how much do literacy rates for males and females differ in the districts? Between maps for different time periods: did fertility rates decline since the last census?

5. Workshop on Census Cartography and Management - October 2007 GIS provide advanced functionalities for census dissemination  Combination of: Census database: data at any geographical level Geographical database: geographical structure of the country + cartographic representation

6. Workshop on Census Cartography and Management - October 2007 Different Uses of Maps  Geographical selection  Direct selection of a user-defined area  Area delineation  Buffer zone  Areas of influence  Modelling: spatial smoothing

7. Workshop on Census Cartography and Management - October 2007 Geographical selection Use this map to navigate to your area of interest by drilling down to the Geographic Areas that you require.

8. Workshop on Census Cartography and Management - October 2007 Direct selection of a user-defined area...  The user describes the area on which he needs aggregated data by clicking on the components: for example, municipalities

9. Workshop on Census Cartography and Management - October 2007 Area delineation  E.g. Interactive determination of school districts with the same number of children in each school grade by aggregating census dissemination areas

10. Workshop on Census Cartography and Management - October 2007 Buffer zone  How many people live within a 5 miles radius from the hospital ?

11. Workshop on Census Cartography and Management - October 2007 Areas of influence  Commuting distances: daily commuters flow

12. Workshop on Census Cartography and Management - October 2007 Modelling: spatial smoothing  Growth rate of the population between two censuses

13. Workshop on Census Cartography and Management - October 2007 Uses of Graphs: Enriching the Understanding of GIS Data Sets  Exploratory Spatial Data Analysis  Linked Maps, Graphs & Tables  Dynamic Feature Selection  Animation  Visualization over Time

41. 2010 World Census Programme  UNSD development project recently initiated in collaboration with UNICEF to improve DevInfo functionality for Censuses  Three areas of improvement envisioned: allow for multi-dimensional cross- tabulations (eg. by age/sex) instead of just uni-dimensional indicators; improve current mapping facility; and allow for standard tables/graphs according to country-defined templates for census information dissemination (eg. one-page country report)
