Albany is the capital city of the U.S. state of New York, the seat of Albany County, and the central city of New York's Capital District.While Albany experienced a decline in its population due to urban sprawl, many of its historic neighborhoods were saved from destruction through the policies of Mayor Erastus Corning 2nd, the longest-serving mayor of any city in the United States. More recently, the city has experienced growth in the high-tech industry, with great strides in the nanotechnology sector. The city has been a center of higher education for over a century, with much of the remainder of its economy dependent on state government and health care services.
Today, Albany is known for its extensive history, culture, architecture, and institutions of higher education. The city is home to the mother churches of two Christian dioceses as well as the oldest Christian congregation in Upstate New York. Albany has won the All-America City Award in both 1991 and 2009.
