According to a news release from the ACLU, the U.S. Terrorist Screening Center has over 900,000 names in its Terrorist Screening Database (TSDB).

In September 2007, the Inspector General of the Justice Department reported that the Terrorist Screening Center had over 700,000 names in its database as of April 2007 - and that the list was growing by an average of over 20,000 records per month. At that rate, the number of names in the database would exceed 1,000,000 names by the end of July, 2008.

The ACLU launched a watch list counter showing the number of new names supposedly added each day to the list, as well as a number of well-known people who have been put on the list.

Go to the FBI's Terrorist Screening Center FAQ to learn who gets included in the TSDB and whether or not you can find out if you are in it (hint: you can't).
