Helping you get your genealogy right

What’s In A Census?

Census records were, and are, purely for demographic information for the government, but oh, what a treasure trove they are for genealogists! They can carry us back several generations. We get to see parents with children and often, their parents and/or siblings. We might learn that great great grandmother Elizabeth married her next door neighbor or her neighbor’s nephew. There is often a clue that someone was married more than once or that there were children who died before reaching adulthood. In my opinion, the census is the most important genealogical resource we have, simply because of the wealth of information in one place. I highly recommend a subscription to Ancestry.com for the census hunt.

The census records are released when they reach 75 years old. The 1930 census was released in 2005. We won’t see 1940′s until 2015 and believe me, you’ll be chompin’ at the bits to get your hands on it. If you’re relatively new to your genealogy search, you might be wondering exactly what we find in the census? Where do we start? In this article I’ll cover the 1850 through 1930 census noting only the most pertinent things to genealogists. Prior to 1850, only heads of households were named. It get’s tricky with the earlier census.

When you begin your search, it’s always best to start at the latest date possible. Late, as in closest to now. Start with latest and work your way back, so we’ll begin with 1930.

(Note: the official date means all information was to be accurate on *that* date, not the date the census taker actually visited the house.)
