Sources: 1961 data from the Library of Congress; other data from CQ Roll Call and the Pew Research Center. Figures for 114th Congress reflect members of Congress to be sworn in on Jan. 6, 2015. Includes Rep. Michael G. Grimm, R-N.Y., who recently announced his intention to resign effective Jan. 5.

Numbers for total members of Congress vary depending on how many seats were empty – for a variety of reasons – when the data was collected.
