I can speak for the Red Cross. There are 5,000 out of 30,000 to be built for the Red Cross movement. The problem is to estimate the kinds of shelters. Some shelters that have been built are not very sturdy, so it's hard to know what the real count is. Some are permanent homes, and some are essentially lean-tos that won't resist the first winds.
