Maryland Total Resident Population from 2010 - 2022 based on US Census Data

Population density for Maryland's jurisdictions relies on two different data sources from the U.S. Census Bureau: intercensal population data (2010-2020) and the Population Estimates Program (vintage series) for the 2020–2024 period. In both instances, the population is divided by the jurisdiction's total square miles. The vintage sources will be replaced annually with new releases.

The reference date for all estimates is July 1, unless otherwise specified.

The annual time series of estimates begins with the most recent decennial census data and extends to the vintage year. The vintage year (e.g., V2019) refers to the final year of the time series. The reference date for all estimates is July 1, unless otherwise specified. With each new issue of estimates, the entire estimates series is revised.

As each vintage of estimates includes all years since the most recent decennial census, the latest vintage of data available supersedes all previously produced estimates for those dates.
