Cleveland (pronounced /kliːvlənd/) is a city in the U.S. state of Ohio and is the county seat of Cuyahoga County, the most populous county in the state. The municipality is located in northeastern Ohio on the southern shore of Lake Erie, approximately 60 miles (97 km) west of the Pennsylvania border. It was founded in 1796 near the mouth of the Cuyahoga River, and became a manufacturing center owing to its location at the head of numerous canals and railroad lines. With the decline of heavy manufacturing, Cleveland's economy has diversified, becoming more service-based, with growth in the financial, insurance, legal, and healthcare sectors. Cleveland is also home to the Rock and Roll Hall of Fame.
As of the 2000 Census, the city proper had a total population of 478,403, and was the 33rd largest city in the United States, (now estimated as the 43rd largest due to declines in population) and the second largest city in Ohio. The city's population has been shrinking since it peaked at 914,808 in 1950 (which, at the time, was the nation's seventh largest). It is the center of Greater Cleveland, the largest metropolitan area in Ohio. The Cleveland-Elyria-Mentor Metropolitan Statistical Area which in 2000 ranked as the 23rd largest in the United States with 2,250,871 people. Cleveland is also part of the larger Cleveland-Akron-Elyria Combined Statistical Area, which in 2000 had a population of 2,945,831, and ranked as the country's 14th largest.
According to the 2010 Census, which was released on March 9, 2011, Cleveland's population declined 17%, down to 396,815 residents. This places Cleveland among the fastest-declining cities in the United States over the past decade. The state of Ohio is expected to lose two Congressional seats as a result of the 2010 Census and based upon the steep decline in Cleveland's population political observers believe both of those districts will be eliminated in northeast Ohio.
