The city of Columbus spreads over a land area of 494.4 sq km (190.9 sq mi). Its large size relative to many American cities is mostly a result of a long-standing and aggressive policy of annexing surrounding vacant or agricultural land. The city then extends water and sewage lines into the new area so that the land can be developed, thereby encouraging urban growth. The region's relatively flat topography aids the expansion.
Columbus is at the core of a six-county metropolitan region, encompassing Franklin, Licking, Fairfield, Delaware, Pickaway, and Madison counties and covering a land area of 8138 sq km (3142 sq mi). Important suburban communities include Upper Arlington, Worthington, Delaware, Westerville, Gahanna, and Whitehall.
