Finding Ancestors

The 1930 United States federal census might be a helpful resource if you are searching for your ancestors. It contains records of approximately 123 million people in the U.S. and offers valuable insight into American life during the early twentieth century. Its contents include information on household members, military service, citizenship, and immigration. It is a great place to start researching your twentieth-century ancestors if you have no other vital records.

The 1930 census is available online or at regional facilities across the country.

123 Million People Were Counted

The 1930 U.S. federal census counted over 123 million people, 16.1% more than the 1920 census. The Bureau of the Census produced over 35 thousand pages of reports as a result. The test was designed to test enumerators’ ability to follow directions, interpret people’s answers, and record data.

The 1930 U.S. federal census covered information on names, ages, races, relationships, occupations, and house numbers. It also gathered information on the literate level, birthplaces, and other information. However, it was not a complete representation of the people’s lives. While there were some exceptions, the 1930 census was largely unremarkable.


The 1930 U.S. federal census is an excellent starting point if you are looking for your family’s past. Most efficient researchers begin their research with this census and then work backward to find additional records. The first step in conducting a 1930 U.S. federal census search is determining where the person lived at the time of the census.

While the census asked questions about race, citizenship was not the last question. Prior censuses did not ask the question. In the 1930 census, people were asked if they were Mexican or not. Until the 1970s, references to Hispanic Americans were omitted. Supporters of the citizenship question argue that an accurate count of voting-age citizens will allow the federal government to enforce the Voting Rights Act better, which banned many forms of voter discrimination. Moreover, it will help uncover the extent to which minority groups have been harmed by voting restrictions.

Despite the Supreme Court ruling, the citizenship question’s future is unclear. The Trump administration is planning to issue an executive order requiring the inclusion of a citizenship question on the 2020 census. This executive order will most likely be challenged in court.

Street Names And Building Numbers

You may be able to find your ancestors’ addresses by looking for street names in the 1930 U.S. federal census. However, the census does not often describe street names and building numbers. Sometimes, you may have to use an address map to find the correct address. If the street and building name are not described, you can try to search using the building number. If that does not work, you can try using street directories.

The 1930 census was conducted in 48 states and Guam and American Samoa territories. The information gathered during this census included information about race and age and the location of residence. The census also included home ownership, employment, literacy, and birthplace information. The 1930 census required 87,756 census takers and more than 35,700 published reports. The questions on the census included whether the person lived in a home on a farm, was single, or had children. Some people were also asked if they had attended school since September 1, 1929, and whether they could read.

The 1930 U.S. federal census includes information about over 137 million people. It was taken just five months after the Wall Street crash. The resulting documents are the fifteenth United States census and contain 2,667 microfilmed rolls of population schedules. They are only made public 72 years after the official census date.
