resignation, death, or chamber action during a Congress, and retirement, electoral defeat, or

pursuit of another office at the end of a Congress. In the 101st Congress (1989-1990) through
R. Eric Petersen
116th Congress (2019-2020), on average, two Senators and nine Members of the House of
Specialist in American
Representatives have left before the conclusion of a Congress. Over the same period, on average,
National Government
10 Senators and 59 Members of the House left Congress upon expiration of their terms of office.

The data provided here may offer insight concerning the turnover of membership in each

chamber, but any such conclusions should be drawn with care, as there appears to be no pattern
to Member departures. This may be due in part to the individualized nature of congressional careers, which might include
numerous events or actions that could affect Members’ decisions to end their congressional service.

n each Congress, Members leave the House or Senate for a variety of reasons. In the course of
a Congress, those reasons could include resignation, death, or chamber action. At the
Iconclusion of a Congress, Members depart due to retirement, electoral defeat, or pursuit of
another office. In the 101st Congress (1989-1990) through 116th Congress (2019-2020), on
average, two Senators and nine Members of the House of Representatives1 have left before the
conclusion of a Congress. Over the same period, on average, 10 Senators (10% of Senate
membership)2 and 59 Members of the House (13.4% of House membership) have left Congress
upon expiration of their terms of office.
This report provides data on Members who have left Congress between 1989 and 2020. Data are
divided into two broad categories. The first category, “in-term” departures, addresses Members
who leave prior to the conclusion of a Congress. Circumstances of in-term departures include a
Member’s resignation or death, or the action of a chamber regarding a Member’s status.3 The
second category, “complete-term” departures, includes Members who leave the House or Senate
at the completion of their terms. This includes Members who retired, were defeated for reelection,
or who did not run for reelection to the House or Senate because they sought other elective office.
Table 2 provides departure information for the House from the 101st Congress (1989-1990)
through the 116th Congress (2019-2020). Table 3 provides House departures as a percentage of
chamber membership for the same period. Table 4 and Table 5 provide Senate departure
information, and departures as a percentage of chamber membership, respectively, for the 101st-
116th Congresses.
