A foundation executive says some philanthropies may use questions of "capacity" as an excuse not to fund projects in rural America. But in the long run, he says, urban-based philanthropies need rural constituencies to make a difference at the national level. But that’s apparently not what has happened in the recent past. A U.S. Department of Agriculture study released last year showed that rural areas, while they were home to about 19 percent of the U.S. population, received only 6 to 7 percent of private foundation grants awarded from 2005 to 2010. Agriculture Secretary Tom Vilsack called the disparity “tragic,” especially in light of earlier conversations the administration has had with foundation leaders about increasing philanthropy in rural areas.
