To cite census data, name the U.S. Census Bureau as the author, include the exact title of the table or dataset, add the publication year, and give the retrieval URL. That is the short answer to how to cite census data, and it holds true across styles. The exact wording and punctuation change depending on whether you write in APA, MLA, or Chicago style, so use the formulas below to match your assignment.
What to Include in Every Census Data Citation
Census data does not come from a single named author, so every style asks you to build the reference from the same four building blocks before you worry about formatting:
- Author or agency: almost always “U.S. Census Bureau.”
- Title: the exact name of the table, survey, or data product, for example “Population Estimates” or “American Community Survey 5-Year Estimates.”
- Date: the year the data was published or last updated. Use “n.d.” only when the page truly lists no date at all.
- Retrieval information: the date you accessed the data and the full URL, since Census tables can be revised after they first go live.
Use the Built-In Citation Tool on data.census.gov
The fastest way to cite census data is to use the Cite button built into data.census.gov, which generates a ready-made citation for the exact table you are viewing in one click. Open the table you used, click “More Tools” above the results, then select “Cite.” The Census Bureau’s own guidance on citing its products confirms this tool generates a citation you can paste directly into your reference list, though you should still check it against your assigned style guide. If you would rather build the fields yourself, the same rules used for citing a government website apply here, since the agency is a federal source.
Tip: the Census Bureau’s citation policy page also covers how to cite its research papers, working papers, and technical documentation. For those longer publications, follow the same structure as citing a report instead of a data table.
How to Cite Census Data in APA
To cite census data in APA 7th edition, treat the Census Bureau’s table as a webpage on the agency’s own site and include a retrieval date, since the underlying figures can be revised after you first access them.
Reference list formula: U.S. Census Bureau. (Year). Title of table or dataset [Data table]. Retrieved Month Day, Year, from URL
Example: U.S. Census Bureau. (2020). Population estimates, July 1, 2020 [Data table]. Retrieved March 3, 2026, from https://data.census.gov/
In text, you can cite it two ways. Parenthetical: (U.S. Census Bureau, 2020). Narrative: According to the U.S. Census Bureau (2020), the population grew by… If you want a shortcut for the reference list entry itself, an APA citation generator can format the brackets and punctuation for you once you have the four building blocks above.
How to Cite Census Data in MLA
To cite census data in MLA 9th edition, list the U.S. Census Bureau as the author and put the exact name of the data set in quotation marks as the title of the work, just as you would for any other web page.
Works Cited formula: U.S. Census Bureau. “Title of Data Table.” Name of Survey, Publication Date, URL. Accessed Access Date.
Example: U.S. Census Bureau. “Comparative Economic Characteristics.” 2015-2019 American Community Survey 5-Year Estimates, 2020, data.census.gov. Accessed 3 Mar. 2026.
In text, cite the first few words of the title in quotation marks, since Census tables rarely give you a page number to point to, for example (“Comparative Economic”). An MLA citation generator can help assemble the punctuation once you have the title and access date.
How to Cite Census Data in Chicago Style
To cite census data in Chicago’s notes-bibliography style, open with the U.S. Census Bureau as author, add the table’s title in quotation marks, name the collection it belongs to, and close with the access date and URL.
Bibliography formula: U.S. Census Bureau. “Title of Table,” Name of Collection, accessed Access Date, URL.
Example: U.S. Census Bureau. “QuickFacts: Austin City, Texas,” QuickFacts, accessed March 3, 2026, https://www.census.gov/quickfacts/.
Citing Census Maps and Statistical Visualizations
The Census Bureau also publishes interactive maps and chart-based visualizations of its statistics, not just plain tables, and these need one extra detail in the citation: the visualization type. Add “[Map]” or “[Data Visualization]” after the title so a reader knows they are looking for an image or interactive tool rather than a spreadsheet. APA example: U.S. Census Bureau. (2023). Population Change by County, 2020 to 2023 [Map]. Retrieved March 3, 2026, from https://www.census.gov/library/visualizations/. The same statistics often appear as a table, a map, and an interactive chart on the same page, so name the specific visualization you viewed instead of linking to the agency’s homepage.

How to Cite a Census Data File You Downloaded (CSV or Excel)
When you export census data as a CSV or Excel file instead of viewing it on a webpage, the citation still needs the same four building blocks, plus the file format in brackets. APA example: U.S. Census Bureau. (2023). Median Household Income by County [CSV file]. Retrieved March 3, 2026, from https://data.census.gov/table/ACSST5Y2023.S1901. Keep the original file name or table ID somewhere in your citation or an appendix, since file names on data.census.gov can change between downloads and a reader may need that identifier to locate the exact version you used.
Citation Style Comparison at a Glance
The table below lines up APA, MLA, and Chicago side by side so you can check the author format and in-text pattern for each style without rereading three separate sections.
| Style | Author format | In-text citation |
|---|---|---|
| APA | U.S. Census Bureau. (Year). | (U.S. Census Bureau, Year) |
| MLA | U.S. Census Bureau. “Title.” | (“Short Title”) |
| Chicago | U.S. Census Bureau. “Title,” | Footnote or (U.S. Census Bureau Year) |
Common Mistakes When Citing Census Data
The most common mistake when citing census data is dropping the exact table title and replacing it with a vague link to the Census Bureau’s homepage, which makes the source impossible for a reader to relocate.
Do this: U.S. Census Bureau. (2022). Median household income in the past 12 months (in 2022 inflation-adjusted dollars) [Data table]. Retrieved March 3, 2026, from https://data.census.gov/table/ACSST1Y2022.S1901
Not this: Census Bureau, data.census.gov, accessed 2026.
The second example fails because it drops the exact title, so a reader could never rebuild the same source from it. When a header on data.census.gov is incomplete, add the missing detail in brackets, such as [for Austin, TX], to keep the citation reproducible.
FAQ
Do I need to cite census.gov if the data is public information?
Yes. Public domain does not mean citation-free. You still need to credit the source so readers can verify and find the same numbers you used.
What if the census table has no listed date?
Use “n.d.” in APA, or the copyright date shown at the bottom of the page in MLA and Chicago, since nearly every Census page carries one.
Can I cite the American Community Survey the same way as the decennial census?
Yes, with one change. Name the specific survey and its estimate period in the title, for example “2019-2023 American Community Survey 5-Year Estimates,” instead of just “Census.”
