In the 119th Congress, ** percent of congressional representatives were women, an increase from *** percent of members in 1991. The biggest increases in female representation were seen between 2018 and 2019, as well as 2020 and 2021.

While the average age of members of Congress in the United States has gradually risen in recent years, this number decreased slightly with the beginning of the 119th Congress in 2025. This Congress first convened on January 3rd, 2025, and will end on January 3, 2027. In this Congress, the average age in the House of Representatives was ** years, and the average age in the Senate was ** years.

This study contains aggregate socioeconomic and demographic data as well as electoral returns for the offices of the United States President and United States Representatives for the elections of 1966-1970 for the congressional districts of the 93rd Congress. Data are provided for the number of votes cast for the Democratic candidates and the Republican candidates, the percentage of votes received by the winning party, and the total number of votes cast in the 1966, 1968, and 1970 elections for United States Representatives, as well as the total votes cast for the office of president, and the number of votes cast for each party's presidential candidate in the 1968 election. Information is also provided on housing characteristics, employment, income, poverty level, and military enrollment for the 93rd congressional districts. Demographic variables provide information on age, race, sex, marital status, education, and place of birth for the population of these congressional districts. In addition to the congressional district level, data aggregated to the state level are also available.

The 119th Congressional Districts dataset reflects boundaries from January 03, 2025 from the United States Census Bureau (USCB), and the attributes are updated every Sunday from the United States House of Representatives and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Information for each member of Congress is appended to the Census Congressional District shapefile using information from the Office of the Clerk, U.S. House of Representatives' website https://clerk.house.gov/xml/lists/MemberData.xml and its corresponding XML file. Congressional districts are the 435 areas from which people are elected to the U.S. House of Representatives. This dataset also includes 9 geographies for non-voting at large delegate districts, resident commissioner districts, and congressional districts that are not defined. After the apportionment of congressional seats among the states based on census population counts, each state is responsible for establishing congressional districts for the purpose of electing representatives. Each congressional district is to be as equal in population to all other congressional districts in a state as practicable. The 119th Congress is seated from January 3, 2025 through January 3, 2027. In Connecticut, Illinois, and New Hampshire, the Redistricting Data Program (RDP) participant did not define the CDs to cover all of the state or state equivalent area. In these areas with no CDs defined, the code "ZZ" has been assigned, which is treated as a single CD for purposes of data presentation. The TIGER/Line shapefiles for the District of Columbia, Puerto Rico, and the Island Areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands) each contain a single record for the non-voting delegate district in these areas. The boundaries of all other congressional districts reflect information provided to the Census Bureau by the states by May 31, 2024.

The 110th Congressional District Summary File (100-percent) (110CD100) contains the 100- percent data, which is the information compiled from the questions asked of all people and about every housing unit. Population items include sex, age, race, Hispanic or Latino, household relationship, and group quarters. Housing items include occupancy status, vacancy status, and tenure (owner occupied or renter occupied). The file contains subject content identical to that shown in Summary File 1 (SF 1).

This data release is composed of tables from a database of United States Congressional statistics spanning the time period 1789 through 1989. The sources of the data were studies in the ICPSR collection and other historical texts and studies. There are eleven data files in total, including two additional tables that have been added since the first release. Some files contain records for additional Congresses. The rows in the various files describe different entities. For example, in the Votes Table file, each row contains a record of a vote by a particular member on a particular roll call vote. The Member Table file contains a record for each member of Congress, while the Serves Table file contains a record for each member for every Congress in which he or she served. See the descriptions of each file in the codebook for details about its contents. The data from the various files can be combined by matching the fields that they have in common. Cross-file searches should be conducted using the Member_ID field. However, not every file has the Member_ID field. In those cases, an alternative common field should be used.

This data collection contains information on the opinions of United States congressmen and women on their roles in Congress, the roles and functions of Congress, congressional organizations and procedures, and the problems and effectiveness of Congress. Three general types of respondents were interviewed: general, leader, and top leader respondents. Respondents were asked about their position on various proposals for congressional reorganization, such as the use of electronic voting devices, four-year terms of office, and year-long congressional sessions, and their opinions on the likelihood of these proposals being adopted. Other items probed their views on issues such as the protection of minority interests, party bloc vote, moral-based decisions, rule of the majority, equality of Congress and the Executive branch, party compromise, degree of influence of lobbyists, and pressing congressional problems. Demographic items specify age, occupation, education, previous political experience, political party affiliation, length of service in Congress, congressional leadership position, ranks, and committee membership and functions, as well as voting records, constituency characteristics by region and district, percentage of total party unity votes, conservative coalition support, and bipartisan support.

The Congressional District Summary File contains the data compiled from the questions asked of all people and about every housing unit in the 2010 Census. The Congressional District Summary File (113th Congress) (CD113) contains the data compiled from the questions asked of all people and about every housing unit in the 2010 Census. Population items include sex, age, race, Hispanic or Latino origin, household relationship, household type, household size, family type, family size, and group quarters. Housing items include occupancy status, vacancy status, and tenure (whether a housing unit is owner-occupied or renter-occupied). The file contains subject content identical to that shown in the 2010 Census Summary File 1.

This data set matches district demographic information to a member of Congress's legislative actions from 1972 through 2013. The unit of analysis is individual members of Congress. For each member of Congress there is data on: personal characteristics for age, gender, race, ideology, etc. district information for income, education, employment, etc. legislative information for number of bills introduced, number enacted into law, etc. committee information

The Congressional District Summary File contains summary statistics on population and housing subjects derived from the responses to the 2010 Census questionnaire. Population items include sex, age, race, Hispanic or Latino origin, household relationship, household type, household size, family type, family size, and group quarters. Housing items include occupancy status, vacancy status, and tenure (whether a housing unit is owner-occupied or renter-occupied). The summary statistics are presented in 333 tables which are tabulated for states, the District of Columbia, Puerto Rico, congressional districts, and areas in hierarchical sequence within congressional districts, such as census tracts, county subdivisions, places, and American Indian/Alaska Native/Hawaiian Home Land areas. There are 261 population tables and 62 housing tables shown for all levels of geography in the file and 10 population tables shown only for states, the District of Columbia, Puerto Rico, and congressional districts. With one variable per table cell and additional variables with geographic information, the collection comprises 2,548 data files, 49 per state, the District of Columbia, and Puerto Rico. This data collection is supplied in 53 ZIP archives. There is a separate archive for each state, the District of Columbia, and Puerto Rico. The last archive contains a Microsoft Access database shell and additional documentation files besides the codebook.

Congressional districts of the 99th Congress are matched to census geographic areas in this file. The areas used are those from the 1980 census. Each record contains geographic data, a congressional district code, and the total 1980 population count. Ten states were redistricted for the 99th Congress: California, Hawaii, Louisiana, Maine, Mississippi, Montana, New Jersey, New York, Texas, and Washington. The data for the other 40 states and the District of Columbia are identical to that for the 98th Congress. (Source: downloaded from ICPSR 7/13/10)

Please Note: This dataset is part of the historical CISER Data Archive Collection and is also available at ICPSR at https://doi.org/10.3886/ICPSR08404.v1. We highly recommend using the ICPSR version as they may make this dataset available in multiple data formats in the future.

Us House Congressional Representatives serving Macon-Bibb County.

Congressional districts are the 435 areas from which members are elected to the U.S. House of Representatives. After the apportionment of congressional seats among the states, which is based on decennial census population counts, each state with multiple seats is responsible for establishing congressional districts for the purpose of electing representatives. Each congressional district is to be as equal in population to all other congressional districts in a state as practicable. The boundaries and numbers shown for the congressional districts are those specified in the state laws or court orders establishing the districts within each state.

Congressional districts for the 108th through 112th sessions were established by the states based on the result of the 2000 Census. Congressional districts for the 113th through 115th sessions were established by the states based on the result of the 2010 Census. Boundaries are effective until January of odd number years (for example, January 2015, January 2017, etc.), unless a state initiative or court ordered redistricting requires a change. All states established new congressional districts in 2011-2012, with the exception of the seven single member states (Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont, and Wyoming).

For the states that have more than one representative, the Census Bureau requested a copy of the state laws or applicable court order(s) for each state from each secretary of state and each 2010 Redistricting Data Program state liaison requesting a copy of the state laws and/or applicable court order(s) for each state. Additionally, the states were asked to furnish their newly established congressional district boundaries and numbers by means of geographic equivalency files. States submitted equivalency files since most redistricting was based on whole census blocks. Kentucky was the only state where congressional district boundaries split some of the 2010 Census tabulation blocks. For further information on these blocks, please see the user-note at the bottom of the tables for this state.

The Census Bureau entered this information into its geographic database and produced tabulation block equivalency files that depicted the newly defined congressional district boundaries. Each state liaison was furnished with their file and requested to review, submit corrections, and certify the accuracy of the boundaries.

These data depict the 117th Congressional Districts and their representatives for the United States. Congressional districts are the 435 areas from which members are elected to the U.S. House of Representatives.
