Baltimore är den största staden i delstaten Maryland i USA. Den upptar en yta av 238,5 km² och har 620 961 invånare. Baltimore är fristående från countyt Baltimore County som helt omger staden.
Founded in 1729, Baltimore is the second largest seaport in the Mid-Atlantic. Baltimore’s Inner Harbor was once the second leading port of entry for immigrants to the United States and a major manufacturing center. After a decline in major manufacturing, industrialization and rail transportation, Baltimore shifted to a service-oriented economy, with the Johns Hopkins Hospital (founded 1889), and Johns Hopkins University (founded 1876), now the city’s top two employers.
The city had a population of 622,104 in 2013; in 2010, that of B M Area was 2.7 million, the 20th largest in the country.
With hundreds of identified districts, B has been dubbed “a city of neighborhoods”. Famous residents have included the writers Edgar Allan Poe, Edith Hamilton, Frederick Douglass, and H.L. Mencken; jazz musician James “Eubie” Blake; singer Billie Holiday; actor and filmmaker John Waters; and baseball player Babe Ruth. In the War of 1812, Francis Scott Key wrote The Star-Spangled Banner, later the American national anthem, in the city.
Almost a quarter of the jobs in the Baltimore region are in science, technology, engineering and math, in part attributed to its extensive undergraduate and graduate schools.
