  2. Mozambique 1997 Census • Census 97 national results released in late 1999 • floods in Gaza and Inhambane – February 2000 • Census was the only source of information for lowest geographical levels • but … Census results were only published by province/district/admin post/locality; not village • in fact, a complete list of the approximately 10,000 villages did not even exist at the time

  3. Mozambique 1997 Census • INE organized an emergency mobilization: • 30 clerks (former data entry operators) • 1 month of work • analyzed census maps, determined a single lat/long coordinate for each village • information was verified, then put into ArcView GIS • male/female population, number of households also • overlaid with flood impact data from sat. imagery • coordinated with WFP, funded by GOM+USAID • Result: a very good estimate of the number of people affected by the floods
