Strengthening Rural Communities, Bread of the World Institute's 15th annual report, particularly Chapters 4 and 5, could be of interest to developers in rural areas around the world and in the United States: http://www.bread.org/institute/hunger_report/2005-pdf.htm . Chapter 5, Strengthening Rural Communities in the United States, includes an interesting map showing "Non-metro counties with net out-migration" from 1980-2000. If you are writing any grant proposals that address the needs of rural areas, this report may be of interest.
