The 1930 Census contains records for approximately 123 million Americans. The census gives us a glimpse into the lives of Americans in 1930, and contains information about a household’s family members and occupants including: birthplaces, occupations, immigration, citizenship, and military service.
The census can be a valuable tool to use when researching your twentieth-century ancestors because it contains records for approximately 123 million Americans. If you had family in the United States during the early twentieth century, you are likely to find at least one relative’s information within these census records. This makes the 1930 census a good place to start research if you are a beginner, or if your family, vital, or religious records are missing.
The 1930 census began on 2 April 1930 for the general population of the United States. (The enumeration in Alaska began on 1 October 1929.) Regardless of when an individual was contacted, all responses were to reflect the status of the individual as of 1 April 1930.
Enumerators (census takers) collected the following information for each household:
- Address (name of the street, avenue, or road; house number)
- Occupant (name of each person and their relationship to head of family)
- Residence (whether home is owned or rented; value of home; whether home is farm residence; whether home has a radio)
- Personal (sex, race, age, marital status, college attendance, ability to read and write, birthplace, and birthplace of parents)
- Citizenship (language spoken before coming to the United States; year of immigration; whether naturalized or alien; ability to speak English)
- Occupation (trade or profession; industry or business working in; class of worker; whether worked the previous day; line number of unemployment schedule)
- Military (whether veteran or not; war or expedition participated in)
Note: Individuals in Alaska, and Indians were asked slightly different questions. For example, Indians were not asked about their mother’s country of origin, but which tribe she belonged to.
Using the microfilm from the 1930 census, Ancestry.com created images of all the available census records. In addition, Ancestry.com indexed all the names in the census so they are searchable online.
- Servicemen were not recorded with their families in the 1930 census; they were treated as residents of their duty posts. If you’re looking for someone in the military, you should not assume they will be listed in their home town.
- Children that were born between the official start date of the census and the actual day of enumeration were not included. Individuals that were alive on the official start date of the census but deceased by the actual day of enumeration were included.
- Indians were included in the enumeration of the general population, though they were asked different questions than the general population.
- The census contains great information, but some data may not be completely accurate. For example, individuals may not have known the answers to certain questions; the census taker may have asked a neighbor for information if the family could not be contacted; and people did not always give truthful information.
- Family members may not be included in the index because of errors or omissions, but may appear in the actual census records. If you can’t find the individual you’re looking for, don’t give up. By searching through states, cities, and towns, you may be able to find record of the individual in the actual records.
- If you encounter illegible writing, you may want to study the handwriting of the enumerator who recorded the census form you’re looking at. You can do this by picking out the most legible letters and words and working from there. For example, the enumerator listing Abraham Lincoln in the 1860 census (Illinois) wrote the letter "L" in a way that resembles an "S". Without looking at other words on the page, one might think that he was a "Sawyer" instead of a "Lawyer."
- When searching, you might want to choose the "Soundex" spelling option instead of using exact matching. (Soundex lets you search based on the phonetic spellings of names.) Searching phonetically can be useful because census takers may have made spelling errors, or created "Americanized" versions of foreign names.
- This is the last census in which individuals were asked whether they could read or write.
- Unlike previous censuses, this census did not ask individuals for their year of naturalization.
- This is the first census in which individuals were asked: the value of their home, or the amount of rent paid each month; their age at the time of their first marriage; the specific war a man had fought in.
- The 1930 census is the only census to ask whether the occupants of the home owned a radio.
- Based on the census, the average number of people in a household was 4.1.
- In 1930, the average life expectancy for an American was 59.7 years.
- The leading country for people of foreign birth was Italy (1.8 million).
- Ancestry.com used microfilm from the National Archives Records Administration (NARA) to create its digitized images of the census.
What do the abbreviations in the 1930 census schedules mean?
Those recording census information in the year 1930 were provided sheets by the government on which information was to be recorded. At the bottom of these pages were found a set of instructions, abbreviations to be used, and which entries were required to be recorded. The following is a list of abbreviations that were to be used in their respective columns. (The information provided is transcribed directly from the census schedules.)
Abbreviations were to be used in the columns as shown:

What is an enumeration district?
An enumeration district is the geographical area that was assigned to a single census taker.
How many people were included in the 1930 census?
The general census recorded a population of approximately 123,202,624 individuals.
Why would I want to search the census by page number?
Once you have located a relative, you can use the page number to pull up other names from that same page in the census—your ancestor’s neighbors. Neighbors may provide valuable clues that you can use to further your research. During this time period, it was not uncommon for families to remain in close proximity to each other. You might find parents, siblings, or cousins living next door. In addition, groups of families often immigrated and settled together in America. You may find clues about the country and area that your ancestors came from.
Ancestry.com has an easier way to search for neighbors. When you reach an individual’s census record page, you can click the Family and Friends: View Results link to see the individual’s neighbors.
