The 1830 enumeration—the first to use a standardized form—broke down ages even more finely: under 5, 5 to 10, 10 to 15, 15 to 20, and every 10 years to the novel “Over 100.” (Ages were reported as of June 1 for both censuses.)

Deep-dive into US census records and other population counts. From helpful research resources to clues about solving ancestor mysteries, our experts provide solutions to your toughest census conundrums.

A second page of the form records both slaves and “free colored” by gender and age: under 10, 10 to 24, 24 to 36, 36 to 55, 55 to 100, and 100 and up. There’s again a count of non-naturalized white foreigners. New questions ask about persons who are deaf and dumb, separated by white, slaves and free colored; and by age (under 14, 14 to 25, and 25 and up). Blind household members also were counted, but weren’t differentiated. That fine breakdown of ages can help narrow an ancestor’s birth year or make sure you’ve got the right match.

How to Read the 1830 Census

In 1830 Wilcox, Ala., my third-great-grandfather William Chapman appears as age 30 to 40—a perfect fit for the 1796 birth date I have for him. The female age 20 to 30 must be his wife, Mary (born in 1802). The two boys under age 5 fit sons Alpheus (born in 1827) and George (born in 1829).

If I knew the children’s birth order but didn’t already have dates for them, I could at least pencil in “1825 to 1830” as probable birth years for each. The female age 5 to 10 would be my great-great-grandmother Cornelia (born 1823). But who’s the extra male, age 20 to 30? That’s a mystery to solve—one of Mary’s brothers, maybe?—and a potential future clue.

Don’t freak out, however, if these early date ranges don’t always match: William Chapman is listed next door to his mother-in-law, “Mrs. Mary Clough,” whose age is given as 50 to 60. Obviously this is the right woman. Is my 1766 birth date for her wrong? [It appears] she fibbed about her age or the enumerator slipped up. In any case, because Mary’s a widow, I can pencil in her husband’s death date as before 1830.
