U.S. Census Records

Does your family tree have any generations that lived in the United States? If so, FamilySearch’s U.S. census records may help you discover more about your ancestors. Census records are an integral source for family history research; they contain valuable information that can connect generations.

Every 10 years, the United States Census Bureau conducts a national census. Since the first U.S. census was taken in 1790, 23 censuses have been recorded in the United States. Of those 23 census collections, 16 are now available to the public. A census record can tell you not only where and when your ancestor lived, but may also describe their occupation, other members of their household, and even small details about their life, such as previous military service or whether they owned a radio set.

Why Is a Census Taken?

One reason a census is conducted is for taxation purposes. However, the impact of a census can be felt at all levels of a community. When a country takes a census, it allows officials to see the growth and change impacting the nation. With this information, a government can see where to allocate federal and state funds. The United States also uses census information to determine the number of representatives each state receives in state and federal legislatures.

US Census Records and population growthSince its first years as a declared nation, the United States has grown significantly in population. If you’re a student of American history, you’re probably familiar with many of the historical and political changes that have contributed to this staggering growth.

In 1790, the U.S. consisted of only 13 states, and the population was already around 3,929,214. Eighty years later, 37 states were considered part of the United States, and the population had risen by over 800 percent. In 1940, when the population was over 132 million, the U.S. was almost at it its current state count (missing only Alaska and Hawaii). By 2010, despite the addition of only two states, the population had increased by more than 150 million from the 1940 figure. This increase means that in 2010, the United States population was nearly 8,000 percent higher than the population estimated in the first census!

Federal and State Census Records

Historically, two main types of censuses have been taken in the United States: the federal census and state censuses. These two types of censuses were often taken five years apart from each other. However, not every state conducted a state census, and no state has conducted a census since the Massachusetts state census in 1985. These state census records can be especially useful in family history research, however, as some states or territories may not have been completely covered in a federal census, or the federal census may have missing information. By searching both federal and state censuses, you can gather an understanding of where your ancestors lived and who they were.

How Does the United States Census Change?

Questions and recorded information change with each census. These changes most often reflect current events in the country. They can also reflect socioeconomic changes or political changes the country is going through during a decade.

Typically, census records have become more detailed each year. The first United States Census recorded information only about the heads of households; other household members were counted according to gender. Census records since then have added increasingly detailed information on every individual as the country has grown and society has changed.

How censuses are taken has also changed over the years. If you lived in the United States in 1940, you may have been asked to fill out a longer census form than your neighbor. The census takers (enumerators) used a more detailed questionnaire for only a portion of the population. 1960 was the first year the U.S. census was processed almost entirely by computers after it had been gathered.

US Census Records Changes and Time Line

When you are searching through census records, it can be useful to consider how each year’s records were different and what information might be available in the census records you are viewing.

The 72-Year Rule and Other U.S. Census Facts

A unique rule prevents census records from becoming available to the public until 72 years after the census was taken. This rule helps protect the identity of people enumerated in past censuses who are still living. Currently, all census records are available up to the year 1940; the 1950 census will become available in April 2022.

You can learn other interesting facts about the census as you dig into its history. The United States Census Bureau wasn’t a permanent government agency until 1902. (The secretary of state was in charge of the first censuses.) Many employees and volunteers for various organizations have worked behind the scenes to gather the census record collections and make them searchable. Each census offers a wealth of genealogical information that can connect generations.

  1. I have lived at the same residence for over 12 years, and not one census taker has knocked on my door. Nor have I received a form to fill out. When my family, in 75 or more years, looks for me in census records, they won’t find me

  2. This compiled information is very informative. I wish I had something in writing like this when I first began searching.

  3. My great, great grandparents were in the US by 1850s. They are not on any census records. Ancestry had church records, by I can’t find church records on Family Search. Their graves are in a cemetary in or around Russellville, but there are no records of their death, either through Ancestry of Family Search. I can’t find their cemetery either, so I am at a complete loss of what to do next.

    1. If you’re restricting your search to online resources only, you are going to miss quite a bit. While getting better, online records at familysearch and Ancestry are only a part of the resources you should look at. Try looking at libraries or genealogy clubs in the areas that they lived in to see if there are any local records you could search.

    2. Sharon. When I tried to find my family I typed Haynes, my name and found nothing. I knew the house where they lived. And the name of the neighbors. I looked for the neighbors and then looked next door. There they were under the name Hayner. So you should try different spelling. Just a thought. I have transcribed many census records and have made many mistakes.

  4. Everyone, it seems, is claiming Native American ancestry here of late. I am claiming it as well. We have photos. We have witness testimonial. What I do not have is my great grandmother on the Dawes Rolls. She never left Alabama for Oklahoma. In addition, she never registered her baby girl. Out of fear, I suppose. While I can find records of my grandfather as an infant, as well as my great grandparents, I can find no further trace of my grandfather after the 1880 census. I have never found anything about his wife, my paternal grandmother. I am not grasping at straws. I know without any doubt that her mother was a full blood Native American. I don’t even want to gain anything. I only wish to know more about my great grandmother and her people. I am not understanding how in the world did my paternal grandparents escape documentation all those years? And living basically in the same area? With 12 living children! I wish to further my discoveries but am standing before the proverbial brick wall.
