Since the release of the 2020 Decennial Census, we are preparing online data dashboards to help visualize the data at different geographies. We will be adding more dashboards and map applications as we continue to analyze the data.

Where Does the Data Come From? The majority of data in the Profiles above are drawn from the U.S. Census Bureau.
The American Community Survey (ACS) is an ongoing survey conducted each year by the U.S. Census Bureau to provide the latest information on the social and economic characteristics of communities across the United States. It includes questions about age, race, family characteristics, income, housing costs and transportation mode, among other household and population characteristics.
The ACS replaced the long form of the Decennial Census in 2010. It provides the latest demographic data for our communities each year. Each month, the ACS goes out to a sample of households across the country – about 3.5 million households are contacted by the U.S. Census annually to complete the ACS survey. The Census then rolls these responses into one-year, three-year and five-year estimates. For places with a population of less than 20,000, data is accumulated over a five-year period to provide a statistically reliable sample. ACS data is available down to the census block group level.
More information on the American Community Survey can be found in this Information Guide published by the U.S. Census Bureau.
The Decennial Census is mandated by the Constitution and takes places every ten years. The data collected determines the distribution of federal funding to local communities. It provides an official count of the entire U.S. population to Congress. The goal of the Decennial Census is to conduct a full count of the population, covering basic demographic information (age, sex, and race).
Between each Decennial Census, the Census Bureau’s Population Estimates Program uses data on births, deaths and migration to measure population change. This data is available for the nation, and each state, county and city across the country.

Baltimore City’s Housing Typology Map: Baltimore City’s Planning Department and the Department of Housing and Community Development collaborate with The Reinvestment Fund (TRF) to produce a Housing Market Typology (HMT) every three years. The resulting HMT map classifies city housing markets into eight categories using data indicators such as median sales price and foreclosure rates. The Housing Market Typology was last updated in 2017.
