About Delaware

Delaware, officially the State of Delaware, is the second-smallest state by area (after Rhode Island) at 2,489 square miles. With just over 1 million residents, Delaware is known as "The First State" because it was the first to ratify the U.S. Constitution on December 7, 1787. Despite its small size, Delaware packs remarkable economic clout as the legal home to over 60% of Fortune 500 companies.

Geography & Climate

Delaware features coastal plains, beaches, and flat terrain. Major geographic features include:

  • Highest point: Ebright Azimuth (448 ft), lowest high point of any state
  • Major water bodies: Delaware River, Delaware Bay, Atlantic Ocean
  • 28 miles of Atlantic coastline including Rehoboth Beach
  • Three counties: New Castle, Kent, Sussex—fewest of any state

Corporate Capital of America

Delaware is the legal domicile for over 60% of Fortune 500 companies and more than 1.5 million business entities. This corporate concentration results from Delaware's business-friendly legal framework and Court of Chancery, established in 1792, which specializes exclusively in business law.

Tax-Free Shopping & Tourism

Delaware has no state sales tax, making it a shopping destination for neighboring states. Delaware's beaches, particularly Rehoboth Beach known as "The Nation's Summer Capital," attract millions of tourists annually seeking coastal escapes and tax-free shopping.
