Summary

[edit]
Description The Global Estimated Net Migration By Decade: 1970-2000 data set provides estimates of net migration for each one square kilometer grid cell over the three decades from 1970 to 2000. Estimates for South America from 1970 to 1980 were developed using spatial population distribution data and taking into account subnational rates of natural increase. Net migration was estimated by subtracting the population at the beginning of the decade from the population at the end, and then subtracting the estimated natural increase (births minus deaths). The residual is net migration (in-migration minus out-migration).
