context_page_description: Jefferson Hills is a borough in Allegheny County, Pennsylvania, United States. It includes the community of Large. In the 2010 census the population was 10,619. Jefferson Hills was created as Jefferson Township, incorporating on January 22, 1828, and named after Thomas Jefferson. The borough is a part of West Jefferson Hills School District. Before 1998, the borough was known as Jefferson.
context_section_description: The total area of the borough of Jefferson is 16.8 square miles or 10,752 acres. Its history dates back to January 22, 1828 when it was created as a township from the old Township of Mifflin. At that time, the community was called "Jefferson Township" in honor of Thomas Jefferson.
  In 1845, Snowden Township was formed from a part of Jefferson Township. Population of the township in 1860 was 1,601 persons, in 1870 it was 2,066 persons, and it reached a total population of 3,227 persons in 1880 (about equal to the population of 1930). Jefferson Township became a First Class Township in 1914, and in 1950 Jefferson was chartered as a borough. The borough of Pleasant Hills seceded from Jefferson Township in 1947 and by so doing, drastically reduced the population and urbanized area of the township.
  Jefferson Hills is located along the southern border of Allegheny County and is primarily residential in nature, with approximately one-third of its area presently being used for residential purposes. The residential use is primarily single-family dwellings with slightly over one percent being multiple-family units. Another third of the borough exists in the form of open space and or vacant ground, with the balance being made up of industrial, commercial, mining, and farming land uses.
  The major portion of Jefferson Hills drains into two watersheds, the Peters Creek watershed, which ultimately drains into the Monongahela River at Clairton, and the Calamity Hollow and West Elizabeth watershed, which drains to the Monongahela River in the vicinity of West Elizabeth.
  
  Present development has occurred almost exclusively in the flat upland areas. These developments are scattered and separated by large open tracts and or hills and valleys.
  The area was the geographic base of the Peters Creek Rangers during the Revolutionary War.
