Where can I find an official list of each state's congressional delegation sizes for the 118th Congress 2023?
Executive Summary
An official, authoritative list of each state's congressional delegation sizes for the 118th Congress (2023–2025) is available from the Congressional Research Service report and federal sources; the most direct official reference is the Library of Congress/Congress.gov compilation "Membership of the 118th Congress: A Profile" which summarizes House seats by state alongside Senate counts. For corroboration and user-friendly breakdowns, the U.S. House website lists members by state and the Senate site confirms the two Senators per state, while public aggregators such as Ballotpedia and Wikipedia compile the same data into tables and comparison tools [1] [2] [3].
1. Where the authoritative government record lives — read it here and save it
The single most authoritative public document that compiles state-by-state delegation sizes for the 118th Congress is the Congressional Research Service synthesis available via Congress.gov titled "Membership of the 118th Congress: A Profile." That CRS product aggregates official counts, noting there are 435 voting House seats apportioned among the states and two Senators per state, and provides tables breaking out each state's number of Representatives and party composition for the 118th Congress [1]. This CRS compilation is prepared for Congress, published by the Library of Congress, and is suitable as an official reference for researchers, journalists, and the public seeking the formal apportionment and membership snapshot for the 2023 convening.
2. House and Senate official sites: how to reconstruct the list yourself
If you prefer to build the list directly from primary federal sources, the U.S. House of Representatives site provides a directory of Representatives organized by state and district, which lets you count delegation sizes and verify party affiliation, while the U.S. Senate site confirms each state’s two Senators and their party affiliations. Using the House directory to tally seats by state plus the Senate roster yields the same state-level delegation sizes reported in the CRS profile; this approach is the primary-source method for independent verification and is kept current with vacancies, special elections, and member changes [2].
3. Public aggregators: convenience with caveats
Non-governmental aggregators such as Ballotpedia and certain Wikipedia pages present the data in more accessible, comparative formats, including side-by-side comparisons of delegation sizes across Congresses and changes due to reapportionment. These sources are useful for quick visual summaries and historical comparisons—Ballotpedia, for example, offers pages comparing delegation sizes between the 117th and 118th Congresses and between the 118th and 119th (where applicable). However, these sites compile from public records and may lag or interpret CRS/House data; they are best used as secondary confirmation rather than the definitive legal source [3] [4].
4. What the official numbers actually say about apportionment and state changes
The apportionment that produced the 118th Congress seats was finalized after the 2020 Census and reflected in CRS tables: total House seats remained at 435, distributed according to the 2020 reapportionment rules, with states gaining or losing seats as determined by the Census apportionment formula. The CRS profile and House seat-by-state tables document which states gained representation and which lost seats entering the 118th Congress; these shifts explain much of the inter-state variance in delegation size and are the formal basis for the state counts reported in all official compilations [1] [5].
5. Cross-checking, dates, and potential pitfalls to watch for
When using any source, cross-check publication dates and note that membership can change during a Congress due to resignations, deaths, or special elections; the CRS report and House/Senate directories are the best places to track these updates because they are maintained with official corrections. For context on partisan control and balance in the chambers during the 118th Congress, independent government-affairs outlets like Bloomberg Government analyze power dynamics and may provide daily-updated directories for subscribers; these are useful for contemporaneous balance-of-power snapshots but are not replacements for the official rosters [6] [2]. Always rely on CRS/Congress.gov or the House/Senate official pages for the canonical counts.
6. Bottom line and practical links you can use right now
To get an authoritative state-by-state list of congressional delegation sizes for the 118th Congress, start with the CRS "Membership of the 118th Congress: A Profile" on Congress.gov and then cross-check against the U.S. House members-by-state directory and the U.S. Senate roster. For easy comparison and historical context, consult Ballotpedia’s comparative pages, but treat them as secondary verification. These combined sources give a complete, official, and corroborated picture of each state’s delegation size for 2023 [1] [2] [3].
