Census Statistics
Many people begin their genealogy research starting with the widely available U.S. census records. The U.S. began taking a census every 10 years starting in 1790. The records from 1790 to 1840 contain only the name of the head of the household and limited information about the other individuals in the residence. That changed in 1850 when the census began listing each member of the household individually.
Look how Pennsylvania has grown! The following table details the population of the state from it's first census through 1940. The 1940 census is the last year currently available for genealogy use. The 1950 census won't be available until 2022. Information is shown for 1890, but that census was mostly lost due to a fire and mishandling in the 1920's and 1930's.
