 The 2010 census recorded a population of 4,120.There has been a large-scale cessation of industrial activities in the region.The decrease in the population is associated with the decline of regional heavy and medium industries, especially the steel-making industry, all once fed by the cheap transportation on the Monongahela River which extends from upstream of Charleroi well into northern West Virginia and north & downstream past McKeesport to the mouth of the Monongahela at Pittsburgh.
