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

The data reflects Maryland's Intercensal Estimates of total residential population from both decennial and non-decennial counts. The total residential populations from 1790 to 1890 are based on the decennial census data, utilizing sources from the IPUMs National Historical Geographic Information System (NHGIS). For the years 1900 to 2020, both decennial and non-decennial population counts were produced by the Population Distribution Branch of the U.S. Census Bureau. Intercensal estimates are generated every 10 years following the decennial census, with estimates from previous decades being revised to align with the most current census data.

Annual Population Estimates for the United States, States, Metropolitan Statistical Areas, Micropolitan Statistical Areas, Counties, Incorporated Places, and Minor Civil Divisions; and for Puerto Rico and Its Municipios // Source: U.S. Census Bureau, Population Division // The contents of this file are released on a rolling basis from December through May. // The estimates are developed from an April 1, 2020 base population and may incorporate changes resulting from the Count Question Resolution program and/or geographic program revisions. // The Office of Management and Budget's statistical area delineations for metropolitan, micropolitan, and combined statistical areas, as well as metropolitan divisions, are those issued by that agency. // Current data on births, deaths, and migration are used to calculate population change since April 1, 2020. An annual time series of estimates is produced, beginning with April 1, 2020 and extending to the vintage year. The vintage year 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. Additional information, including historical and intercensal estimates, evaluation estimates, demographic analysis, research papers, and methodology is available on website: https://www.census.gov/programs-surveys/popest.html.

Tabulates acres by land use category as of 2018 for each of Maryland’s 23 counties and Baltimore City. Derived from the Maryland Department of Planning’s 2018 Statewide Land Use Dataset (2024 Edition). Given methodology changes, this dataset is not comparable with MDP’s previous Land Use Land Cover products and should not be used to assess change over time.

Dataset includes total residential sales by zip code for 2010-2022. When a zip code crosses a county boundary, it is split into two records by county.

Subcounty Resident Population Estimates // Source: U.S. Census Bureau, Population Division // Note: The estimates are based on the 2010 Census and reflect changes to the April 1, 2010 population due to the Count Question Resolution program and geographic program revisions. See Geographic Terms and Definitions at http://www.census.gov/popest/about/geo/terms.html for a list of the states that are included in each region and division. For functional status codes, see http://www.census.gov/geo/reference/codes/place.html. All geographic boundaries for these population estimates are as of current vintage year. An (X) in the 2010 Census field indicates a government that was formed or incorporated after the 2010 Census. See additional information on these areas in the Geographic Boundary Change Notes (http://www.census.gov/geo/reference/boundary-changes.html). For population estimates methodology statements, see http://www.census.gov/popest/methodology/index.html. // The estimates base populations for the unincorporated part of Gadsden County, FL and Rockwell City city, IA (located in Calhoun County) include different group quarters population than enumerated in the 2010 Census. After comparison with other Census Bureau data collection efforts, the Census Bureau determined that the 2010 Census enumeration of the group quarters population in these areas was incomplete. Although not eligible for the Count Question Resolution program, the Census Bureau concluded that including the additional group quarters population for these two areas into the population estimates base would provide more accurate estimates for each area. // Each year, the Census Bureau's Population Estimates Program (PEP) utilizes current data on births, deaths, and migration to calculate population change since the most recent decennial census, and produces a time series of estimates of population. 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., V2014) 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 Census Bureau revises estimates for years back to the last census. 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. The Population Estimates Program provides additional information including historical and intercensal estimates, evaluation estimates, demographic analysis, and research papers on its website: http://www.census.gov/popest/index.html.
