How to Cite a Census Record (Evidence Explained)

Guide · Updated July 2026

To cite a United States census record in Evidence Explained style, record the census year, the jurisdiction (state, county, and township or city), the enumeration district, the page or sheet number, the dwelling and family number, the head of household, the database or repository where you found it, and the date you accessed it. Then express it three ways: a source-list entry, a full first-reference note, and a short form for later references.

What a census citation must capture

Census year and jurisdiction — e.g. 1880 U.S. census, Jefferson County, Ohio, Steubenville.
Enumeration district (ED) — the area assigned to one enumerator; how the census is physically organized.
Page/sheet, dwelling number, family number — the precise location on the page.
Head of household — the name the entry is filed under.
Where you found it — the database (with images) or the repository, and the date accessed.

The steps

Identify the census and place. Note the year and the full jurisdiction, smallest unit first.
Record the ED and page. Copy the enumeration district, and the page or sheet number as printed.
Record the dwelling and family number, and the head of household. These pinpoint the exact household.
Record where and when. Name the database with images (or the physical repository) and the date you accessed it.
Write all three forms. A source-list entry, a first reference note, and a short form.

Worked example

These are the three forms a template produces for one 1880 census household. This is the exact structure the AncestorOS census citation template generates:

Source list entry

1880 U.S. census, Jefferson County, Ohio, population schedule, Steubenville, enumeration district (ED) 120, p. 14, dwelling 98, family 102. Digital image. Ancestry. https://www.ancestry.com : 2026.

First reference note

1880 U.S. census, Jefferson Co., Ohio, pop. sch., Steubenville, ED 120, p. 14, dwell. 98, fam. 102, Michael Strauss household; digital image, Ancestry (https://www.ancestry.com : accessed 2026); citing NARA microfilm publication T9.

Short form (subsequent references)

1880 U.S. census, Jefferson Co., Ohio, ED 120, p. 14, dwell. 98, fam. 102, Michael Strauss household.

Common mistakes

Citing the index instead of the image — the transcription can be wrong; cite what you actually looked at.
Omitting the enumeration district, which is what lets someone relocate the page when an index fails.
Leaving out the access date for an online database, which is part of a complete citation.

Frequently asked

The first reference note is a full footnote used the first time you cite a source, with every detail needed to relocate it. The source-list entry is the bibliography form, organized for a list of all sources used. The short form is an abbreviated footnote for later references to the same source.

The area assigned to a single census enumerator, and the unit the census is physically organized by. Recording the ED lets another researcher find the page even when a name index fails or misreads the name.

Cite the image you actually examined. Index entries are derivative transcriptions and are often wrong; the image is the original evidence.

Evidence Explained by Elizabeth Shown Mills is the de facto citation standard for American genealogy. It defines the three citation forms and templates for dozens of record types.

Yes, on the Pro plan. Its census template captures the year, jurisdiction, enumeration district, page, dwelling and family number, head of household, repository and access date, and generates all three forms. There are 14 templates across 11 record categories.
