  2. Goal: Use GIS to discover which parts of the world might hold clues on how to better fight child malnutrition. In general, we expect that child malnutrition will correlate with poverty. But what parts of the world do much better or much worse than expected based on their poverty rate? Decision-makers: - The UN - Regional Bodies - National Governments - Local Governments - NGOs - Academia Goal provides avenue for further investigation.

  3. Export data to R, run regression weighted by population (only for 52 countries with national-level malnutrition data) Expected relationship: M = 0.256*P+7.72 But the fit isn't very good...

  4. Regressing Malnutrition vs Log(GDP per capita) Weighted by Population Expected relationship: CM = -16.7*log(GDP_capita)+79.1 Much better fit! per capita

  5. Caveats: -Assumed homogeneity of national data -Poverty and GDP are both flawed measures -Time disparities in data -Difficulties in collecting accurate data -Populous nations can skew weighted regression -Assumed linear relationships -Poverty is apples-to-oranges -Does weight really measure malnutrition?

  6. Where to Investigate? Regressing by Poverty Regressing by GDP/capita -15 Bolivia -14 Ukraine -14 Swaziland -14 Colombia -13 Venezuela -27 Zimbabwe(?) -20 Laos -17 Moldova -14 Georgia -14 Paraguay Less Malnutrition than expected: +33 Nepal +31 Pakistan +30 Maldives +29 Bangladesh +28 Cambodia +26 Maldives +23 Pakistan +22 Bangladesh +21 Cambodia +21 Nepal More malnutrition than expected: (Unweighted average across regions)
