Composite Census Index

  You no longer need to open each census or census index to locate your relative. For the convenience of our users, we have created a composite of all the Madison County census indices for the transcribed census shown in the table below. Census indices for all Federal censuses from 1850 through 1930 and Iowa State censuses from 1849 through 1895 plus 1925 are now in one alphabetized master list titled the Composite Census Index.


The counting of Madison County citizens began with the Iowa State Census of 1849 which listed names of heads of the household and the number of residents therein.  This was followed the next year by the 1850 Federal Census. Frequent Iowa state censuses  were taken early on and in 1885, became a decennial event through 1925.
