City of Columbia MD Information

Columbia MD

Columbia is a census-designated area in Howard County, Maryland. It is the heart of the Baltimore-Washington metro area. It is a planned community that consists of 10 villages.


Columbia was founded on the belief that a city can improve its residents’ quality life. James W. Rouse, the developer and creator of Columbia, saw the new community as a reflection of human values and not just economics and engineering. Columbia, which was opened in 1967, was designed to eliminate all the problems of sub-division design at that time and also abolish racial, religion, and class segregation.


Columbia is a humid subtropical climate with cool winters, and hot, muggy Summers.


According to the 2009-2013 census estimates, the median household income in the CDP was $99877. The CDP’s per capita income was $46,374. The CDP had a per capita income of $46,374. This was 4.1% of households and 6.6% of the total population.


Columbia’s original plan called for a minibus network connecting village centers along a separate right-of-way, which allowed for denser development. Although the routes were never constructed, the Columbia Association operated minibuses under the name “ColumBus”. They were eventually taken over and operated by Howard County. Six Howard Transit bus routes connected Columbia with neighboring areas, such as Ellicott city and BWI Airport. They were then replaced by the Regional Transportation Agency of Central Maryland in 2014. Many Maryland Transit Administration (MTA), routes offer access to Washington and Baltimore. MTA weekday commuter buses connect Columbia to the Washington Metro. Columbia does not have any rail stations, but the Dorsey MARC train station is serviced by RTA buses.
