congress-terms.csv has an entry for every member of congress who served at any point during a particular congress between January 1947 and Februrary 2014.

House membership data is from the @unitedstates project, with Congress meeting numbers added using code from GovTrack:

• https://github.com/unitedstates/congress-legislators
• https://github.com/govtrack/govtrack.us-web/blob/master/us.py#L93

Senate membership data is mostly from the New York Times Congress API combined with birthdays from @unitedstates. (It does not include the birthday of Sen. Elmer Thomas.)

In addition, we added an incumbent field to each record.
