FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Timonium’s census tracts, against the rest of the country; all of them together, very low. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.

From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Baltimore County.
