As the rhetoric on illegal aliens residing in the U.S. heats up, it would be nice to have some reliable facts with which to work. The Congressional Research Service has put them together for us--the numbers, areas of residence, time of arrival, participation in the work force--all in one tightly written pdf file.

Update:

Doug Ross has reviewed the Congressional Research Service's paper on illegal aliens in the U.S. and winkled out some interesting data and charts. For example, 23% of all illegal aliens in the U.S. reside in California and 5% of the U.S. work force consists of illegals.
