First-Term Members of the House of Representatives and Senate, 64th – 113th Congresse
Summary
This report provides summary data on the number of Senators and Members of the House of
Representatives who first entered Congress between the 64th Congress (1915-1917) and the 113th
Congress (2013-2014). First-term membership is divided into two broad categories in each
chamber: Members chosen prior to the convening of a Congress, and those chosen after a
Congress convenes. The resulting data, combining pre-convening and post-convening first-term
Members, provide a count of all Members who served a first term in the House or Senate.
Since the convening of the 64th Congress, 4,126 individuals have entered the House of
Representatives for their first, or “freshman,” terms as Representatives. An additional 26 have
begun service as Delegates or Resident Commissioners. During the same period, 825 individuals
began their first terms in the Senate.
Data on pre-convening first-term Members provide partial insight into the extent of membership
turnover in the House and Senate since 1915. In both chambers, the data suggest that the overall
number of first-term Members elected to Congress who take their seats at the convening of a new
Congress has declined since the 64th Congress. This appears to be consistent with findings that
argue that the duration of Members’ careers has been increasing in the past century. Taken on
their own, post-convening first-term Member data do not reveal clear patterns within individual
Congresses, or over time. This is due in part to the wide range of reasons that a seat in the House
and Senate may become vacant in the course of a Congress, and the circumstances under which it
may be filled.

First-Term Members of the House of Representatives and Senate, 64th – 113th Congresse
Introduction
This report provides summary data on the number of Senators and Members of the House who
first entered Congress between the 64th Congress (1915-1917) and the 113th Congress (2013-
2014).1 Since the convening of the 64th Congress, 4,126 individuals have entered the House of
Representatives for their first, or “freshman,” terms as a Representative. An additional 26 have
begun service as a Delegate or Resident Commissioner. During the same period, 825 individuals
began their first terms in the Senate.2
First-term membership is divided into two broad categories in each chamber; Members chosen
prior to the convening of a Congress, and those chosen after a Congress convenes. The “pre-
convening” category includes Members who were elected in the general election, and in any
special elections held prior to the convening of a Congress.3 The 64th Congress was chosen as the
starting point for data collection because it was the first Congress for which Senators were chosen
by direct popular election. This provides a single date upon which most Members in both
chambers are chosen to serve prior to the convening of a Congress. In the Senate,4 the pre-
convening category also includes any Senators who were appointed to the Senate prior to the
convening of a new Congress.5
The “post-convening” category includes Members who joined either chamber after the convening
of a Congress. Means by which seats may be filled by a post-convening Member in either
chamber include special elections held after a Congress convenes6 or electoral challenges that
result in a new Member being seated.7 In the Senate, a first-term Member may also join the
chamber through appointment or special election.8
1 Data for the 113th Congress are current as of the date of publication.
2 Detailed data identifying the number of first-term Members of the House and Senate by name, chamber, Congress,
party, and timing of election (House and Senate) or appointment (Senate only) are available to congressional offices
upon request.
3 An example of this type of election came prior to the convening of the 65th Congress (1917-1919), when
Representative Charles Brand of Georgia was first elected to the House by a special election held on January 11, 1917.
Representative Brand took the seat left vacant by the death of Representative Samuel Tribble, who had won reelection
but died before being sworn in. See U.S. Congress, House, Biographical Directory of the United States Congress 1774
– 2005: The Continental Congress, September 5, 1774, to October 21, 1788, and The Congress Of The United States

Vacancies: Perspectives and Contemporary Developments, by Thomas H. Neale.
5 One such example is the appointment of Nathan Lynn Bachman of Tennessee, who was appointed to the United
States Senate after the resignation of Senator Cordell Hull. Senator Bachman was appointed on February 28, 1933,
before the convening of Congress on March 9, 1933. See Biographical Directory of Congress, p. 347, at
http://www.gpo.gov/fdsys/pkg/GPO-CDOC-108hdoc222/pdf/GPO-CDOC-108hdoc222-3-73.pdf.
6 An example of this occurred during the 89th Congress (1965-1966), when Representative Jerome Waldie of California
was first elected to the House on June 7, 1966, following the death of Representative John Finley Baldwin, Jr. on
March 9, 1966.See Biographical Directory of Congress, p. 431, at http://www.gpo.gov/fdsys/pkg/GPO-CDOC-
108hdoc222/pdf/GPO-CDOC-108hdoc222-3-73.pdf.
7 In the House, instances of successful challenges have been rare, occurring eight times between the 64th and 113th

First-Term Members of the House of Representatives and Senate, 64th – 113th Congresse
Members whose congressional service in one chamber is not consecutive are counted as first-term
Members in the first instance of their service as a Member, if that term occurred between the 64th
and 113th Congresses. For example, a Representative who served in the 87th Congress (1961-
1962), and 89th Congress (1965-1966), but not the 88th Congress (1963-1964), would be counted
as a first-term Representative only for the 87th Congress. Members with service in the House and
Senate are listed in each capacity in which they served a first term,9 if those terms occurred
between the 64th and 113th Congresses.10
The resulting data, combining pre-convening and post-convening first-term Members, provide a
count of all Members who served a first term in the House or Senate. Data on pre-convening first-
term Members provide partial insight into the extent of membership turnover in the House and
Senate since 1915, and are discussed in greater detail below. Post-convening first-term Member
data do not reveal clear patterns within individual Congresses, or over time. This is due in part to
the wide range of reasons that a seat in the House and Senate may become vacant in the course of
a Congress, and the circumstances under which it may be filled.
Data describing the number and partisan breakdown of first-term membership in the Senate are
provided in the “Data Tables” section in Table 6. Data describing first-term Representatives are
available in Table 7, Table 8 in the same section provides information for Members of the House
serving as a Delegate or Resident Commissioner.
(...continued)
Congresses (1915-2013), with none occurring after the 75th Congress (1937-1938). For example, following the 1936
general election, the New Hampshire Secretary of State certified that Representative Arthur Jenks had won election,
after a recount, by 30 votes. Representative Jenks presented his credentials as a Representative –elect, took the oath of
office, and served from January 3, 1937, until June 9, 1938. He is counted as a pre-convening first-term Member. A
House Committee on Elections in 1938 reviewed the results of the election and found that Representative Jenks’
opponent, Alphonse Roy, won the election and deserved to be seated. The House concurred in this finding, and
Representative Roy was sworn in on June 9, 1938. Representative Roy is counted as a post-convening first-term
Member for the 75th Congress. See Biographical Directory of Congress, p. 357 at http://www.gpo.gov/fdsys/pkg/GPO-
CDOC-108hdoc222/pdf/GPO-CDOC-108hdoc222-3-75.pdf.
The only example of a successful contested Senate seat since the introduction of direct elections to that chamber
occurred in the 69th Congress (1925-1927). Senator Smith Brookhart of Iowa was certified the winner of the 1924
election and served in the 69th Congress from the day the Senate convened on March 4, 1925, until April 12, 1926,
when his election was successfully challenged and he was removed. Senator Daniel Steck was subsequently sworn in to
fill the seat, and is counted as a post-convening senator. See Biographical Directory of Congress, p. 321 at
http://www.gpo.gov/fdsys/pkg/GPO-CDOC-108hdoc222/pdf/GPO-CDOC-108hdoc222-3-75.pdf.
8 Due to the differences in state laws regarding the appointment or election of individuals to fill a U.S. Senate vacancy,
there have been instances of two or more people holding the same Senate seat in the course of a Congress. For
example, in the 77th Congress (1941-1942), Senator James Byrnes of North Carolina resigned on July 8, 1941 upon his
appointment as an Associate Justice of the Supreme Court. On July 22, 1941, Alva Lumpkin was appointed to the
Senate seat by the governor of North Carolina and was sworn in. On August 1, 1941, Lumpkin died, and a new Senator,
Roger Peace, was appointed on August 6, 1941. On November 6, 1941, Burnet Maybank won a special election and
was sworn into office. Senators Lumpkin, Peace, and Maybank were all counted as post-convening first-term Senators.

CDOC-108hdoc222-3-77.pdf.
9 Prior to the 64th Congress, some Members served as a Delegate, and then as a Representative after the territory they
represented was admitted to the Union as a state. (The data collected do not identify any Members who served as both
Delegate and Representative in the 64th Congress or later.)
10 For example, prior to his service in the Senate, Edward Lewis (Bob) Bartlett of Alaska served as a Delegate in the
House. Senator Bartlett is counted as a first-term Delegate for the 79th Congress (1945-1946), and as a first-term
Senator for the 86th Congress (1959-1960).

Turnover
Data on pre-convening first-term Members provide insight into the extent of membership
turnover in the House and Senate. Table 5 in the “Data Tables” section summarizes the number of
pre-convening Members entering the House and Senate at the beginning of a new Congress, and
as a percentage of the seats in each chamber. These data identify most of the turnover in each
chamber, but they may not identify all of the changes in every Congress, since they only reflect
the number of Members who served their first term in the chamber. Some Members who had
prior service that is not consecutive may have been reelected to the House, or reelected or
appointed to the Senate.11 In those circumstances, the data in Table 5 may understate the extent of
change in some Congresses.
House Turnover
Since the 64th Congress, the average turnover in the House with each election has been 72 seats,12
or 16.61%. The election with the greatest change occurred in 1932, resulting in a turnover of 158
seats, or 36.32% of the Representatives between the 72nd Congress (1931-1933) and the 73rd
Congress (1933-1934). The smallest pre-convening turnover among Representatives in the House
occurred in the 101st Congress (1989-1990), with a change in 30 seats, or 6.90%. Figure 1
provides a graphic representation of the percentage change in House membership between the
64th Congress and the 113th Congress. The data suggest that while there is no consistent pattern of
change from Congress to Congress, the overall number of new, pre-convening, first-term
Representatives has declined. This appears to be consistent with some academic findings that
argue that the duration of Members’ careers have been increasing in the past century.13

Congresses convening prior to the 74th Congress (1935-1936). Table 2 provides data on the
number of seats and percentage change of the six Congresses that saw the least change between
the 64th and 113th Congresses. The smallest pre-convening turnover among Representatives in the
House occurred in the 101st Congress (1989-1990), with a change in 30 seats, or 6.90%. All of the
smallest changes occurred after the 89th Congress (1965-1966). The distribution of greater
changes occurring earlier in the period between the 64th-113th Congresses, and smaller changes
happening in the later period may also support contentions regarding the duration of
Representatives’ careers. Data describing the number and partisan distribution of first-term
Representatives are provided in Table 7. Table 8 provides similar information for Members of
the House serving as a Delegate or Resident Commissioner.

Senate Turnover
As shown in Table 5, in the “Data Tables” section, since the 64th Congress, the average number of
pre-convening first-term Senators each Congress has been 10. Table 6 shows that the 79th
Congress (1945-1946) produced the greatest change in membership with 33 new Senators,
34.38%, taking seats in the chamber in the course of the Congress. Figure 2 provides a graphic
representation of the percentage change in first-term Senate membership between the 64th
Congress and the 113th Congress. The data suggest that while there is no consistent pattern of

change from Congress to Congress, the overall number of pre-convening, first-term Senators has
declined since the 64th Congress. Changes in Member career patterns in the Senate may explain
some of the change.

Table 3 provides data on the number of Senate seats and percentage change of the five
Congresses that saw greatest change between the 64th and 113th Congresses. All of those
Congresses occurred before the 87th Congress (1961-1962). The smallest turnover of pre-
convening Senators occurred in the 102nd Congress (1991-1992), with a change of three seats. In
the 73rd Congress (1932-1933), a 15-seat change amounted to a percentage change of 15.63%,
since the Senate had 96 seats. Table 4 provides data on the number of seats and percentage
change of the seven Congresses that saw the least change between the 64th and 113th Congresses.
Smaller changes appear to be more evenly distributed through the latter half of the Congresses
observed. This may be explained in part by electoral patterns. While the entire House stands for
election every two years,14 only one-third of the seats in the Senate are subject to election in the
same period; barring change in membership for other reasons, this assures that two-thirds of
Senate membership will remain unchanged. Data describing the first-term membership of the
Senate is provided in Table 6.
