Geography
Baltimore is in north-central Maryland on the Patapsco River close to where it empties into the Chesapeake Bay. The city is also located on the fall line between the Piedmont Plateau and the Atlantic coastal plain, which divides Baltimore into “lower city” and “upper city”. The city’s elevation ranges from sea level at the harbor to 480 feet (150 m) in the northwest corner near Pimlico.
Demographics
In 2011, then-Mayor Stephanie Rawlings-Blake said her main goal was to increase the city’s population by improving city services to reduce the number of people leaving the city and by passing legislation protecting immigrants’ rights to stimulate growth. Baltimore is sometimes identified as a sanctuary city. In 2019, then-Mayor Jack Young said that Baltimore will not assist ICE agents with immigration raids.
Baltimore City’s population has declined overall from 2010 to 2020 by about 34,830 people, representing a 5.6% drop. The official US census places the city’s population at 585,708 for 2020. The year between 2018 and 2019 had the largest year-to-year population loss, and in 2020 Baltimore lost more population than any other major city in the United States.
