  lowest geographical levels

  10,000 villages did not even exist at the time

Mozambique 1997 Census

• Political impact everyone saw how important the
  census was for Mozambique
• Humanitarian impact the census saved lives
• This is an example of census advocacy it wont
  be as difficult to get funding for Census 2007
• This can be considered a good example of how
  census data is the best (and only) source of
  small area data.

Mozambique 1997 Census

• Didnt involve high-tech solution, but applied
  all the resources used during the census to get
  results quickly and with a limited budget.
• Subsequent work has refined the spatial data,
  using GPS, etc. (examples land-mine locations
  can be layered on top of population data,
  thematic atlas, poverty mapping).
