The Maryland State Data Center Announces Latest Release of Census Data Estimates

Planning in Progress

A division of the Maryland Department of Planning (MDP), the Maryland State Data Center (MSDC) is the state’s primary liaison with the Census Bureau. MSDC provides Maryland residents, businesses, and local governments with demographic and socioeconomic statistics. It also produces the State’s official population and household projections and develops school enrollment forecasts.

MSDC’s latest release of U.S. Census Bureau 2022 population estimates for Maryland’s jurisdictions, and an associated report, are now accessible on its website. The information presented includes the following metrics:

  • Maryland’s population of 6,164,660 lost 12,533 persons from April 2020 to July 2022.
  • Frederick county posted its fifth consecutive annual population increase adding 15,370 new residents since April 2020, a gain of 5.7 percent.
  • Year-over-year (July 2021 to July 2022), Frederick County’s population increased by 2.4 percent, or by 6,699 residents.
  • Four of the five most populous jurisdictions lost residents from April 2020 to July 2022: Prince George’s County (-20,273), Baltimore City (-15,762), Montgomery County (-9,533), and Baltimore County (-8,339).
  • The population of Anne Arundel County, the fifth largest county in the state, increased by 5,021 from April 2020 to July 2022.
  • Natural increases and international migration to the state’s largest jurisdictions were not sufficient to overcome the significant movement of people out of those counties, which saw a combined 96,198 persons relocate.
  • The data, for the most part, indicate the movement of population out of the state’s inner-ring suburbs to exurban parts of the state.
