About the Region

Mid-Atlantic

The Mid-Atlantic corridor — New York City south through Philadelphia, Baltimore, and Washington D.C. — is the densest and most economically complex region in the country. Finance and media anchor New York; government, defense, and federal contracting anchor D.C.; healthcare and universities anchor Philadelphia and Baltimore. This makes the region one of the most recession-resistant labor markets in the U.S., though the same fundamentals push housing costs persistently high.

Philadelphia and Baltimore offer substantially lower costs than either New York or D.C. while sitting on the same high-speed rail line, making them increasingly attractive to remote workers and hybrid commuters. The New Jersey and Delaware suburbs fill in between, providing family-oriented communities within commuting range of multiple cities. The region's density means genuine walkability in most urban cores, strong transit infrastructure, and cultural institutions that rival anywhere on earth.
