Census dissemination o A census is not complete until the information collected is made

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o The information may be: n included in published tables and reports for general distribution n produced as tables in unpublished form for limited distribution n stored in a database and supplied upon request, or disseminated online (in this case it will be available only to connected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

The power of maps o o o 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: n n 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? Workshop on Census Cartography and Management - October 2007

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