The U.S. Census Bureau celebrates its birthday on August 2. It was 228 years ago, in 1790, that Congress, then in its second year, assigned 350 marshals the responsibility of counting the less than 4 million Americans across the young Union’s 13 states and additional territories.

Every decade since then, the Census Bureau has sought to count and learn about every person living in the United States, and its importance cannot be overstated. Census figures are used to determine congressional representation, federal funding, social and economic planning, and more. While it might seem like an annoyance for some people, an accurate census count determines whether they are represented and supported by their government.

The size of the undertaking, as well as the technology and workforce used to collect this information has changed over time — hand counting was replaced by punch card machines, then basic computers. Today, the Census is finally starting to move to a fully digital system, and is encouraging respondents this year to submit questions online.

Racial and ethnic definitions, for example, are still improving to this day to include marginalized parts of the population. Most non-white and immigrant groups have fallen into the category of “Other” for most of the history of the Census.

24/7 Wall St. reviewed historical information regarding the U.S. Census from the bureau’s site as well as other sources, including an interview with former Census director Vincent Barabba, to collect some important facts on the institution and the decennial Census.

Detailed Findings

The first census included just six questions. By the early 20th century, there were over 30 question. The most recent census had just 10. For the upcoming 2020 Census, the Trump Administration is seeking to include the question, “Are you a citizen?” That addition is being challenged, but if it stands, it will be the first time the question has been asked since 1950.

Many have viewed this move as an intimidation tactic, or even as a plan to learn of illegal immigrants, obtain census records illegally, and then deport them.

As part of our research, we spoke with Vincent Barabba, twice former director of the Census Bureau — from 1979 to 1981 and 1979 through 1981. Barabba remains the only director to have been appointed by both a Democrat and a Republican president.

Barabba expressed confidence that the current laws surrounding the confidentiality of information, as well as culture of the Census Bureau itself, would remain steadfast in the face of any demands by the administration to obtain records, citing several past incidents when government officials have attempted to access this information, to no avail.

He added, though, that the inclusion of this new question could have serious consequences on the response rate of many people living in the country. “When things are believed as real, they are real and have consequences. The law is pretty clear that no one other than Census employees can see the individual data, but that’s a hard one for some people to believe given everything else that is going on.”
