Genealogy Census Records

Census records are the backbone of post-1790 (US) / post-1841 (UK) genealogy: they place a household at a date and place, list ages and birthplaces, and let you trace a family across decades. For a strategy guide on subscriptions see Genealogy Online Services; for related vital records work see Genealogy Wills, Probate & Land; for migration patterns see Genealogy Maps & Migration.

Free national / aggregator

• ★ ★ FamilySearch Census Collections — free; world's largest free census collection. Complete US 1790–1950, full UK 1841–1921 (sourced from Findmypast partnership), Canada, full or partial coverage of dozens of European countries, Latin America, parts of Asia. Indexes searchable; original images attached. The default first stop, period.
• ★ NARA (US National Archives) — free; the official US source. Direct-link images of every US federal census (1790–1950) on Catalog.archives.gov. Less convenient than FamilySearch's index but fully free, no account.
• ★ 1950 US Census — released April 2022; free at NARA, indexed by FamilySearch / Ancestry / MyHeritage.
• Internet Archive census scans — free; volunteer uploads of older censuses, useful for offline mirrors.
• USGenWeb Project — free volunteer-transcribed early US census + colonial-era records.

US (paid bring more index quality)

• Ancestry US Censuses — paid; the most-corrected indexes; image quality high. Required for "every Ancestry hint" research style.
• MyHeritage US Censuses — paid; competitive index; cross-references to other MyHeritage records.
• Findmypast US Censuses — paid; competitive but smaller.

UK & Ireland

• ★ Findmypast — paid; deepest UK & Ireland census coverage 1841–1921 (1921 was a Findmypast exclusive at launch; now broadly available).
• ★ FreeCEN — free; volunteer-transcribed UK censuses (1841–1891 mostly). Slower index quality than Findmypast but free.
• Ancestry UK — paid; competitive UK census coverage.
• TheGenealogist — paid UK; alternative index with extra collections.
• ScotlandsPeople — paid pay-per-view (~£1.50/credit, censuses ~6 credits each); the only legal source of full Scottish census images. Censuses 1841–1911 + 1921 (released 2022).
• Census of Ireland 1901 / 1911 — free at the National Archives of Ireland; the Irish census is exceptional because most pre-1901 was destroyed (1922 PRO fire). 1926 Irish census released 2026.

Continental Europe

• Geneanet — paid + free; French / Belgian / Italian / Spanish census equivalents (recensements, popolazione).
• Filae — paid; French.
• Antenati — free; Italian state archive parish + civil registers (census-equivalents). See Genealogy By Country (Europe).
• Digitalarkivet (Norway) — free; Norwegian censuses 1769–1910.
• Riksarkivet (Sweden) — free; Swedish censuses + church records.
• DK Digital / Rigsarkivet (Denmark) — free; Danish censuses 1787–1940.
• Genealogy Indexer — free; meta-search across Polish / Galician / Yiddish records including censuses.
• Geneteka (Poland) — free; Polish parish + civil records.
• CompGen / Archion (Germany) — Compgen free; Archion paid Lutheran records.
• Matricula — free; Catholic parish books across DACH and elsewhere.

Other regions

• Census Canada — free at Library and Archives Canada (1851 onward); also indexed at Ancestry / FamilySearch / MyHeritage.
• Australian Census — Australia destroys census records by law after collection (privacy); use post-event Electoral Rolls and shipping records via Trove + Ancestry AU.
• NZ Census — also destroyed historically; use electoral rolls.
• South Africa — paid Ancestry coverage; some free at FamilySearch.
• Latin America — FamilySearch parish + civil records; some censuses partially indexed.
• China / Japan / Korea — concept differs (戸籍 family register systems); FamilySearch has some Korean / Chinese coverage; Japan koseki access via Japanese government.

State / territorial / colonial censuses

• State censuses (NY, IA, MN, KS, etc.) — usually free at FamilySearch + paid at Ancestry. Fill gaps between federal years.
• Pre-federal colonial censuses — paid Ancestry has good coverage.
• Indian Census Rolls (Dawes Rolls, etc.) — free at NARA; for Native American research.

Search techniques

• Surname spelling drift — Soundex / Beider-Morse phonetic search beats literal matching for census records.
• Page browsing — when an index fails, locate the household by enumeration district + page from a neighbor you can find.
• 1890 US Census destroyed — fire of 1921 destroyed most. Bridge with 1880 → 1900 via city directories, state censuses (NY 1892, IA 1885 etc.), pension files.
• Pre-1850 US — only head of household named; counted others by age/sex/race brackets. Use to corroborate other sources, not as primary biographical data.
• AI-assisted indexing — FamilySearch's 2024–2026 push has dramatically improved old indexes; re-search a frustrating ancestor periodically.

What's changing in 2024–2026

• FamilySearch Full-Text Search extending beyond censuses to handwritten deeds and probates — uses HTR, finds names census indexes missed.
• 1921 Ireland Census released January 2026.
• 1931 Canada Census released June 2023; full index available 2024 onward.
• Antenati Italian Records expanding rapidly; church-and-civil records cover census-like reconstructions.
• AI re-indexing of old US state censuses surfacing new hits.

Pick this if…

• Default free starting point for any region: FamilySearch.
• US deep research, willing to pay: Ancestry (best indexes) + FamilySearch (free fallback).
• UK & Ireland: Findmypast (best census + parish coverage).
• Scotland (only legal source): ScotlandsPeople pay-per-view.
• Ireland pre-1922: the destroyed-records reality means use 1901/1911 + Griffith's Valuation + church records via FamilySearch.
• Free, no subscription, slow index: FreeCEN (UK) or USGenWeb (US).
• Italy / Continental Europe: Antenati + relevant national archive.
• Bulk research / API access: FamilySearch FS-API (with approval).
