In the early 19th century, Greensburg had very little population growth (see population data table in this article). After 1850, Greensburg became a growing county seat with inns and small businesses. A railroad stop and the discovery of large areas of soft coal nearby made it the center of a vigorous mining industry in the late 19th century and early 20th century. Several coal mines (Greensburg/Keystone Nos. 1 and 2, Hawksworth, and Radebaugh) were opened in and around Greensburg during this period with nearly all of the coal being shipped by rail.
