Between 1821 and 1876, there were 14 state censuses authorized by the State of Missouri. Either constitutional or statutory law mandated that these censuses were to be taken. After the initial census of 1821, the year Missouri attained statehood, a state census was taken every four years from 1824 until 1876, with the exception of 1872. These censuses were usually printed as a fold-out sheet in the Missouri House or Senate Journals, and it is my attempt here to explain why the censuses were taken and some of the more interesting facts about the census counts.
