Every 10 years since 1790, the United States has undertaken the momentous task of counting all of its residents. The 2020 Census is mandated by the Constitution and will count every person living in the United States and five U.S. territories. The primary goal of the 2020 Census is to count everyone once, only once, and in the right place.
Census results determine congressional representation as well as federal funding for states and communities. Every year, more than $675 billion goes toward hospitals, fire departments, schools, roads, and more.
Census 2020 was the twenty-fourth United States Census.

2030 Census
For the 2030 Census, we started early planning in 2019 and are currently in the Design Selection Phase. This phase includes research, testing, and operational planning and design work to inform the selection of the initial 2030 Census operational design.
The 2030 Census will count residents of the United States and five U.S. territories and will mark the 25th population count in the United States.
The data collected by the census is used to determine the number of seats each state has in the U.S. House of Representatives (a process called apportionment) and is also used to adjust or redraw electoral districts based on where populations have increased or decreased. The results also inform decisions about allocating hundreds of billions of dollars in federal funding to communities across the country—for hospitals, fire departments, schools, roads, and other critical programs and services.
News and Updates about the 2030 Census
Preparing for the 2030 Census with the 2026 Test - The 2026 Census Test will be the first of two major on-the-ground tests we conduct in preparation for the 2030 Census.
All major tests require logistical commitment, such as dedicated office space and staff, that helps us evaluate how well the innovations we are planning will perform.
We will conduct the test in six sites and also include a nationally representative self-response testing component.
As we prepare for the 2030 Census, conducting testing like the 2026 Census Test gives us the opportunity to explore innovative technologies and methodologies to enhance our work to conduct a complete and accurate count of the nation.
