Geography and composition
The county contains a mix of urban neighborhoods, older industrial districts, suburban subdivisions and rural tracts. Its landscape and settlement patterns reflect the historical importance of industry and transportation to the region. Municipal boundaries and annexations have shaped a patchwork of cities, towns and unincorporated areas within the county.
History
Jefferson County grew rapidly in the late 19th and early 20th centuries as Birmingham and surrounding communities developed around iron, coal and steel production. That industrial base attracted a large workforce and supported secondary industries. During the mid-20th century, Birmingham became a focal point of the civil rights movement, an episode that left a lasting legacy on the county's civic life and institutions.
Government and services
The county is administered by an elected county commission and a set of officials responsible for courts, public safety, roads and social services. County institutions include hospitals, research centers and educational campuses that serve the wider region; these public- and private-sector employers play a key role in the local economy and in delivering services to residents.

According to the 2000 U.S. census the county had a population of about 662,047; since then demographic shifts, suburban growth and economic change have continued to reshape its communities.
