The United States Federal Census


The first record I recommend using to trace your genealogy in the United States is the census.  Originally the United States Censuses were taken to apportion taxes, and to apportion representation in congress.  Today it is used as a genealogical source throughout the country.  The census is the best genealogical tool available for doing research in the United States because everyone who lived in the United States during a census year is (supposedly) included.  It is quite simple to use and is available on the internet if you have a subscription to or


The United States census has been taken every ten years from 1790 to 2000.  There is a 72 year rights of privacy law so the last census that is available to the general public is the 1930 census.  The 1890 census was partially destroyed by fire, and congress ordered the remainder burned.  There is essentially none of the 1890 remaining.

1920 Census

The 1920 census was taken on 1 January 1920.  The information included on the 1920 census is very similar to the information in the 1930 census.  One important addition is the 1920 census also gives the year of naturalization so that you can find naturalization records and find out where your ancestors came from if they were immigrants.  Heads of households only are indexed on and other head of household indexes are also available on microfilm at many major libraries.  A sample census form can be found here
