The postponement of Zambia’s sixth national census from 2020 to 2022 caused concerns among immunisation professionals in the Chinsali District of Muchinga province. Without critical population data information at their disposal, vaccination service planning depended on broad assumptions about where people and infrastructure were located.

To help resolve this issue, GRID3 partnered with the Health Information Systems Program (HISP) to deliver maps to Chinsali, which included key insights for immunisation microplanning, including information on population (by age and sex), settlement locations, boundaries, points of interest (i.e. health facilities), and health facility catchment areas.
