Why the 2010 United States Census cost thirteen billion dollars to complete

In short: The 2010 decennial census was a massive logistical undertaking, counting over 308 million people across the nation. While it successfully finished under its operational budget, the total cost reached thirteen billion dollars. This massive effort highlights the complex, evolving nature of tracking a population in a modern, diverse society.

The 2010 census served as the 23rd decennial count, a constitutional requirement performed every ten years since 1790. Unlike previous iterations that utilized a long form to gather detailed socioeconomic data, the 2010 effort relied exclusively on a short form. This questionnaire focused on ten basic variables, including age, sex, race, Hispanic origin, and housing tenure. More granular social and economic information was shifted to the American Community Survey, which operates on a rolling cycle rather than a decadal one.

Logistically, the project was immense. The Census Bureau delivered approximately 134 million forms by April 1, 2010, achieving a national mail participation rate of 74%. To ensure accuracy, the bureau hired 635,000 temporary enumerators to conduct non-response follow-up visits for households that did not return their forms. Despite the scale, operational costs were $5.4 billion, significantly lower than the $7 billion budget, thanks in part to higher-than-expected mail participation and unused emergency funds.

The financial trajectory of the census remains a point of scrutiny. The Government Accountability Office noted that costs have roughly doubled each decade since 1970. By 2010, the per-capita cost reached about $42, a figure that dwarfs the per-capita spending of nations like China or India. These expenditures are critical because the resulting data dictates the reapportionment of seats in the House of Representatives and influences the distribution of trillions of dollars in federal funding annually.

The 2010 census also reflected shifting cultural and administrative priorities. While the bureau expanded its language assistance program to 59 languages, it notably lacked an internet response option. Furthermore, the handling of same-sex couples marked a point of nuance; while no specific checkbox existed for same-sex marriage, couples were instructed to identify as spouses, mirroring the reporting method used by opposite-sex married couples.
