  "full_text": "\"San Diego County may have a stunning coastline, incomparable weather and a world-famous zoo, but all that has not been enough to stem the flow of residents leaving the region for fast-growing areas in the West where housing is far cheaper.\"\n\nSo began a recent story by the San Diego Union-Tribune that used Internal Revenue Service migration data, which is offered by the IRE and NICAR Database Library. The U.S. Census Bureau compiles the data, based on personal income tax return information, for the IRS.\n\nThe database allows journalists to track the movement of people and their incomes, in and out of counties, from 1992 through 2002. USA Today used the migration data in an October 2002 report about how migration of affluent Californians has led to the dominance of Republican politicians in the mountain west states.\n\nOther recent updates include the U.S. Federal Aviation Administration Aircraft Registry, which lists all aircraft and aircraft owners registered in the United States (current through February 2003).
