Subscription site Ancestry.com has added the 1930 Mexico National Census (El Quinto Censo General de Población y Vivienda 1930, México) and made the records free to search in celebration of Mexican Independence Day Sept. 16.
With nearly 13 million records, this census counted an estimated 90 percent of the population. Note that citizens from the Federal District, which includes Mexico City, aren’t named.
In its announcement, Ancestry.com calls this the most comprehensive historical Mexican census available online. (FamilySearch.org, the source of Ancestry.com’s index and images, also has the 1930 Mexico census records available in its free historical records search.)
Nearly 30 million Americans—about 10 percent of the US population—can trace their families to Mexico. Other Ancestry.com collections they can use to research their roots are border crossings from Mexico to the United States (1895-1957) and parish records. The records are gathered in a Mexico collection landing page. (The 1930 Mexican census is free to search, but not all the other records in the collection are free.)
