Columbia is a planned community comprising 10 self-contained villages, located in Howard County, Maryland—the second wealthiest county in the United States, according to 2013 U.S. Census Bureau figures. It began with the idea that a city could enhance its residents' quality of life.
Columbia's origins come from a crossroads in eastern Howard County formed by the Columbia Turnpike Road Company when it built a road from the Montgomery Courthouse to Baltimore called the "Columbia Road", now known as U.S. Route 29. A small post office at the crossroads of the turnpike and Old Annapolis Road (present-day MD 108) named "Columbia" opened on August 27, 1874, serving a population of 20 residents as late as 1912. Developer and community associations prefer to acknowledge the completion of the first housing project in the 1960s as the foundation of "Columbia".
