​​What is a Hard to Count (HTC) population?

Over the years, the U.S. Census Bureau has conducted research to identify which particular population groups are undercounted at a higher rate during the enumeration process of the census. Hard to Count groups or HTCs include: young children, highly mobile people, non-English speakers, undocumented immigrants, racial/ethnic minorities, rural and low income families, people experiencing homelessness, the LGBTQ community and people with mental and/or physical disabilities.
