If you need to cite the U.S. Census Bureau (data.census.gov), in APA format, follow APA 7th edition guidelines for webpages on a website with a retrieval date. These rules are used for websites where the content changes over time, like the US Census. 

Make sure to include the following elements in the citation:

• Author: U.S. Census Bureau. 
• Date: Use n.d. for no date since there is no date for this specific web page. 
• Title: Use the name of the data or report 
• Parent organization: U.S. Department of Commerce
• Retrieval date and the URL https://data.census.gov/. It is uncommon to include a retrieval date in APA 7th edition, but you should include it here since contents of a page are designed to change over time
