The population was 8,791 at the 2020 census. It is part of the Pittsburgh metropolitan area. In late 2007, it was proposed that the borough of Beaver and Brighton Township combine. According to a report by the Governor's Center for Local Government Services, the two municipalities would possibly derive a significant financial benefit from uniting. Also being considered was the type of combination: either merger, in which one of the municipalities would be annexed by the other, or consolidation, in which the two would become a single new municipality under a new name. Any union would require voter approval.
