Hard-to-count (HTC) is a term used in demography and statistics to describe groups of people who are difficult to locate, contact, or classify accurately in censuses and large surveys. HTC vulnerability stems from barriers such as unstable housing, frequent mobility, language differences, distrust of government, lack of fixed addresses, and irregular immigration status. These factors increase the likelihood that individuals in HTC groups are undercounted in official censuses, potentially biasing population estimates, resource distribution, and political representation.

Common HTC populations include the homeless and recently homeless, renters in unstable housing, residents of rural or hard-to-reach areas, people with limited English proficiency, immigrants and undocumented residents, mobile workers, and people living in poverty. Children in crowded or unstable housing, people in institutions, and communities with high stigma around Census participation are also frequently identified as HTC. The specific makeup of HTC groups can vary by country, region, and census design.

Measuring and addressing HTC is challenging because HTC status is not fixed; it evolves with migration, policy changes, and local conditions. Undercounts can distort demographic indicators, affect funding formulas, redistricting, and service planning. To reduce HTC, agencies employ targeted outreach, multilingual materials, culturally competent enumerators, partnerships with trusted community organizations, and flexible data collection strategies. Post-enumeration surveys and methodological studies help estimate undercount levels and improve future censuses.

Policy discussions around HTC emphasize equitable data collection and community engagement. Critics note that the label can risk framing communities as problems rather than rights-bearing groups, and that counting alone does not solve access or representation gaps.

Notable data sources include national censuses, large-scale surveys such as the American Community Survey, and methodological reports by statistical agencies and research institutions that study HTC dynamics and estimation techniques.
