CHART FOR AGE GROUPS IN PRE-1850 FEDERAL CENSUS MALES AND FEMALES

 This is for us who aren’t mathematical and have to constantly figure the ages when doing censuses.

We have to be careful, with the calculations.

The 1800 & 1810 census asked for ages ‘though’ a year and then in

1820 they started qualifying that the ages were from one age and ‘under’ the next age. It can make a difference in the dates
