Population housing census support
Today, with major demographic shifts occurring and attention focused on international development, accurate and timely data are more important than ever. A census can represent a country, down to the smallest administrative unit, if conditions allow for it. Territories where a traditional census cannot be conducted countrywide due to inaccessible hard-to-reach areas, disasters or lack of infrastructure, modelled population estimates help to generate quality population data everywhere.
“Within the GRID3 context, this entails support for digital mapping, use of satellite imagery and general increased use of GIS to improve quality of the census.”
Tapiwa Jhamba, Census Advisor, UNFPA
“There are places where census data cannot be collected due to conflict or security issues. The GRID3 programme provides the opportunity to estimate population using satellite imagery, micro-census data, and other geospatial data such building footprints to estimate the population at high-resolution levels and to fill in the data gaps of a census.”
