About State Censuses:

State censuses were often taken in years between the federal censuses. In some places, local censuses were designed to collect specific data, such as the financial strengths and needs of communities; tallies of school-age children and potential school populations to predict needs for teachers and facilities; censuses of military strength, cavalry horse resources, and grain storage; enumeration for revenue assessment and urban planning; and lists to monitor African Americans moving into the northern cities.
