Three hundred five House Members (70% of the House) and 82 Senators (82% of the Senate) have served as elected officials at the local, state, or federal level before arriving in Congress. CQ data also indicate that at least 135 House Members (31% of the House) and 28 Senators (28% of the Senate) have been owners, founders, or executives of businesses or companies.

As has been true in recent Congresses, the vast majority of Members (96% of House Members and 99% of Senators) at the beginning of the 119th Congress have earned at least a bachelor's degree. Sixty-six percent of House Members and 78% of Senators hold advanced educational degrees beyond a bachelor's.16 The CQ Member Profiles at the beginning of the 119th Congress indicate the following:
By comparison, approximately 40 years ago in the 99th Congress (1985-1986), 84.8% of House Members and 88% of Senators held bachelor's degrees. Fifty years ago, in the 94th Congress (1975-1976), 82.5% of House Members and 88% of Senators held bachelor's degrees. Sixty years ago, in the 89th Congress (1965-1966), 74% of House Members and 57% of Senators held bachelor's degrees.18

Notes: Representatives are elected for two-year terms. Senators are elected for six-year terms. Note that 45 Senators in the 119th Congress have previously served in the House. Their House service is not included in this average, nor is the House service of Senators included in previous Congresses.
At the beginning of the 119th Congress, 62 of the House Members (14.1% of the total House membership) had first been elected to the House in November 2024, and 12 of the Senators (12% of the total Senate membership) had first been elected to the Senate in November 2024.20 By comparison, at the beginning of the 118th Congress, 16.8% of the House and 7% of the Senate were newly elected "freshmen."

Ninety-six percent of the Members of the 119th Congress report an affiliation with a specific religion.21
Statistics gathered by the Pew Research Center on Religion and Public Life, which studies the religious affiliation of Representatives and Senators, and CQ at the beginning of the 119th Congress showed the following:
One hundred fifty-five women Members (28.65% of the total membership) serve in the 119th Congress. This is the same total number as at the end of the 118th Congress, but two more than at the beginning of the 118th Congress.23 One hundred twenty-nine women, including 4 Delegates, serve in the House and 26 in the Senate. Of the 129 women in the House, 96 are Democrats, including 2 of the Delegates, and 33 are Republicans, including 2 Delegates. Of the 26 women in the Senate, 16 are Democrats and 10 are Republicans.24
By comparison, 30 years ago in the 104rd Congress (1995-1996), 50 women served in the House, and 9 in the Senate. Forty years ago, in the 99th Congress (1985-1986), there were 23 women in the House, and 2 in the Senate.
There are 66 African American Members (12.2% of the total membership) in the 119th Congress, four more than at the beginning of the 118th Congress.25 Sixty-one serve in the House, including two Delegates, and five serve in the Senate. This number includes two Representatives who are of African American and Asian ancestry, and two Representatives who are of African American and Hispanic ancestry. In this report, each of these four Members is counted as belonging to two ethnic groups. Fifty-seven of the African American House Members, including two Delegates, are Democrats, and four are Republicans. Four of the Senators are Democrats and one is Republican. Twenty-nine African American women, including two Delegates, serve in the House, and two serve in the Senate.26
By comparison, 40 years ago in the 99th Congress (1985-1986), 21 African American Members served in the House, and none in the Senate. Sixty years ago, in the 89th Congress (1965-1966), there were 6 African American Members of Congress, all serving in the House.
There are 56 Hispanic or Latino Members in the 119th Congress, 10.35% of the total membership and 6 fewer than at the beginning of the 118th Congress.27 Fifty serve in the House, including one Delegate and the Resident Commissioner, and six in the Senate.28 These numbers include one House Member who is also of Asian descent, and two House Members who are also of African ancestry; these three Members are counted in both ethnic categories in this report. Of the Members of the House, 38 are Democrats (including one Delegate and the Resident Commissioner) and 12 are Republicans (including one Delegate). Nineteen are women. Of the six Hispanic Senators (two Republicans, four Democrats), one is a woman. By comparison, 40 years ago in the 99th Congress (1985-1986), 14 Hispanic or Latino Members served in Congress. All 14 were male Members of the House.
Twenty-four Members of the 119th Congress (4.4% of the total membership) are of Asian, South Asian, or Pacific Islander ancestry. This is three more than at the beginning of the 118th Congress.29 Twenty-one of them (16 Democrats, 5 Republicans) serve in the House, and three (all Democrats) serve in the Senate. These numbers include two House Members who are also of African American ancestry and one House Member who is also of Hispanic ancestry; these three Members are counted in both ethnic categories in this report. Of those serving in the House, three are Delegates. Eleven of the Asian, Pacific Islander, or South Asian American Members are female: nine in the House, and two in the Senate. By comparison, 40 years ago in the 99th Congress (1985-1986), there were five Asian/Pacific Islander Americans in the House, and two in the Senate. All were male.
There are four Native American (American Indian) Members of the 119th Congress: three in the House (two Republicans and one Democrat) and one, a Republican, in the Senate.30 This is 0.74% of the total congressional membership.
Twenty-six Representatives and six Senators (6.0% of the 119th Congress) were born outside the United States. Their places of birth include Cuba, Germany, Guatemala, India, Japan, South Korea, Peru, and Ukraine. Some of these Members were born to American citizens working or serving abroad.31 The U.S. Constitution requires that Representatives be citizens for seven years and Senators be citizens for nine years before they take office.32
At the beginning of the 119th Congress, there were 98 individuals (18.1% of the total membership) who had served or were serving in the military, the same number as at the beginning of the 118th Congress. According to lists compiled by CQ, the House as of January 2025 had 80 veterans (including 7 female Members, as well as 1 Delegate); the Senate had 18 veterans, including 2 women.33 These Members' service included tours of duty in the Vietnam War and the Persian Gulf War, and combat or peacekeeping missions in Afghanistan, Iraq, and Kosovo. As of February 2025, five House Members are still serving in the Reserves, and three House Members are still serving in the National Guard. Three of the nine female veterans are combat veterans.
The number of veterans in the 119th Congress reflects a trend of decline in recent decades in the number of Members who have served in the military. For example, 64% of the Members of the 97th Congress (1981-1982) were veterans, and in the 92nd Congress (1971-1972), 73% of the Members were veterans.34
