Has the number of millionaire lawmakers in Congress increased over time?
Executive summary
Available reporting shows a clear long-term rise in congressional wealth: multiple analyses conclude that the share and total net worth of members of Congress have grown over recent decades, and by the 2010s and 2020s a majority of members were millionaires [1] [2] [3]. Sources document faster wealth growth among lawmakers than for typical Americans and note concentration at the very top of the wealth distribution in Congress [1] [4].
1. The basic trend: more millionaires in Congress now than in the past
Historical and contemporary reporting finds that the number and share of millionaire lawmakers have increased: Roll Call reports that the “thicker belt” of millionaires included 153 House members and 50 senators in the mid‑2010s and that the cumulative net worth of Congress jumped notably before that Congress [1]. The Center for Public Integrity and OpenSecrets likewise reported that about half or more of members were millionaires in recent Congresses and that median congressional net worth rose since the late 2000s [2] [5].
2. How analysts measure “millionaire lawmakers” — and why comparisons are messy
Observers rely on annual personal financial disclosures that report asset ranges; those disclosures are uneven, sometimes vague, and often report ranges rather than precise values, which complicates exact counting [3]. Roll Call and Ballotpedia compile rankings and estimates from those disclosures, but different methodologies (median vs. mean, inclusion of spouses’ assets, treatment of ranges) yield slightly different totals and trends [1] [6].
3. Wealth growth among lawmakers outpaced typical Americans
Ballotpedia’s Personal Gain Index and related analysis show that members of Congress experienced median annual net‑worth increases while median American household net worth fell or grew much more slowly over comparable periods; Ballotpedia notes a median annual increase of about 1.55% for members versus a decline for the median American in one study window (2004–2012) [4]. The Center for Public Integrity also reported that congressional median net worth rose several percent compared with 2008–2009 levels [2].
4. Concentration matters: gains concentrated at the very top
Reporting emphasizes that most of the gains are at the top end: Roll Call found that the “very top” superrich in Congress drove large portions of growth and that the top 10% held many times the wealth of the bottom 90% — meaning aggregate increases can mask distributional differences [1]. OpenSecrets and other outlets highlight examples of single lawmakers whose net worth rose dramatically, amplifying headline totals [5].
5. Mechanisms driving the rise — multiple, contested explanations
Analysts point to several factors: wealth accumulation before seeking office, later‑in‑life entry to politics (older, wealthier entrants), market gains on investments held by lawmakers, and individual high‑net‑worth newcomers [1] [7]. Ballotpedia’s work suggests members’ portfolios often outperformed average Americans’ returns during certain intervals [6] [4]. Available sources do not offer a single agreed causal model tying all these threads together; different outlets emphasize different drivers [1] [4].
6. Political and ethical implications flagged by reporting
News coverage and watchdog reports connect the wealth trend to debates over representation and conflicts of interest: wealth concentration in Washington raises questions about whose experiences are represented and fuels scrutiny of stock trading by lawmakers and the adequacy of disclosure and recusal rules [1] [8] [9]. Investopedia and fact‑check reporting document concerns about well‑timed trades and calls for stronger safeguards, including blind trusts [8] [9].
7. Limits, disagreements, and what the sources don’t say
Precision is limited: disclosures report ranges; some members’ filings are incomplete; organizations use different methods, so exact counts of “millionaires” vary by dataset [3] [1]. Sources cited here do not provide a single time series with year‑by‑year counts of millionaire members back to the 20th century; therefore, exact annual change rates or a definitive baseline decade‑by‑decade tally are not available in this set of reporting [1] [3].
8. Bottom line for readers
Multiple independent analyses concur that Congress has grown wealthier overall and that a majority of members have been millionaires in recent Congresses, with wealth growth concentrated among the richest lawmakers and outpacing typical American households [1] [2] [4]. But counting exact numbers depends on methodology and imperfect disclosure data; readers skeptical of specific tallies should consult the original compilations from Roll Call, OpenSecrets, Ballotpedia, and the primary financial disclosures for methodological detail [1] [5] [4] [3].
