I can't give you the answers to all the Iowa State Census questions but I can give you most of the years. State wide censuses were for 1856, 1885, 1895, 1905, 1915 and 1925. These are all available through a FHC. There were some earlier census records but I don't think anything state wide. I have already transcribed the 1856 Mills County Census and am now starting the 1856 Madison. If you will click on the following URL there is an explanation for several of these census records and the questions they ask. http://www.rootsweb.com/~iamills/Census/censusndx.htm Cay Merryman M J Moser wrote: > > What information was asked for in the the state censuses from 1845 to > 1900?
