Every Person Counts: The 2030 Census Will Drive Billions in Funding for Connecticut

April 1 marks Census Day, a once-in-a-decade event with significant financial implications for Connecticut. While the decennial census is often seen as a simple population count, it plays an important role in determining how federal funding is allocated. For Connecticut, that translates to billions of dollars each year that support health care, education, housing, and other essential services.

The Project on Government Oversight (POGO) emphasizes the importance of an accurate decennial census count. Census data determines who qualifies for funding, how much Connecticut receives, and which communities are prioritized. Population counts help determine eligibility for programs, such as whether an area qualifies for rural assistance. It may also impact grant decisions, where data on income, population, and community need can determine which areas receive investment. In some cases, census data even influences financial terms, such as interest rates for federal loans tied to local economic conditions.

Population estimates build on the decennial census and provide updated population counts in the years between each official census. Published annually by the Census Bureau and certified by the Connecticut Department of Public Health, these estimates use data on births, deaths, and migration to reflect how Connecticut’s population changes from year to year. Many programs may rely on these yearly estimates, not just the once-a-decade census, to adjust funding and allocate resources more responsively. Because of this, the accuracy of the population estimates depends heavily on the accuracy of the initial census count at the start of the decade.

In Fiscal Year 2023 alone, Connecticut received almost $25 billion in funding across 371 federal programs. Many of these programs rely on an accurate count from census data to guide the allocation of resources. Of the $25 billion, 74% ($18.5 billion) supported Medicaid and Medicare and 10% ($2.5 billion) funded other health-related spending. The remainder supported education, infrastructure, housing, and economic development.

As of February 2026, 24% of Connecticut residents participated in the Medicaid program and 9% participated in SNAP.

Given these stakes, accuracy is essential. An undercount can have long lasting consequences, as individuals who are not counted are effectively overlooked. This can lead to reduced support for health care, schools, infrastructure, and social services. Historically, undercounts have disproportionately affected “hard-to-count” communities, including minorities, low-income populations, and undocumented immigrants.

In preparation for the 2020 decennial census, CTData developed and compiled resources to support outreach efforts across the state. We are already engaging with state agencies, planning regions, and community organizations as the 2030 census approaches.
