State Census Records have many uses for family historians. First, they can fill in the gaps between federal censuses and they can replace information lost when a federal census, such as 1890, was destroyed. Secondly is that state censuses are not closed to public scrutiny for 72 years as are the federal censuses. And finally, is that state censuses often ask different questions than were asked on federal censuses. These local censuses may have been authorized to provide some specific regional data to the local officials.
