Census records are among the most common and important records used by the genealogical researcher. Learning to use them to full advantage is the key to being a successful researcher. The census record may contain valuable information about a family's history, however it must be carefully reviewed and analyzed. We need to research the instructions that were given to the census takers and understand why they asked the questions that they did. Each federal census is different from the one before it. It is important that we learn about the differences and take them into account.
It is important that we pay careful attention to the date the information was taken. Each census had an official date that the information was to be taken. We need to always check and see if the enumerator included this on the record. Sometimes a person might have died after the official date but have been included in the record. The same holds true for births.
The official dates that the U.S. Federal Census was taken "as of" a certain date are as follows: Census year Date of Census
1800 - First Monday in August (4th)
1810 - First Monday in August (6th)
1820 - First Monday in August (7th)
1830 - 1900 June 1
1910 - April 15
1920 - January 1
1930 - April 2 (in Alaska began on 1 October 1929.)
