Towns & Villages in Lycoming County

Lycoming County has 35 named places on record: 1 city, 9 boroughs and 4 census-designated
places with an official population count, plus 21 smaller unincorporated communities with no
government of their own. CDP stands for census-designated place; Unincorp. covers hamlets and
crossroads recognized by the U.S. Geological Survey’s gazetteer but never incorporated.

Two names on this list invite confusion. Muncy borough is a separate municipality from Muncy
Creek Township directly south of it and Muncy Township to the north — all three carry the
Muncy name but govern different ground. Rauchtown, a census-designated place sometimes listed
under Lycoming County online, is in fact centred in neighboring Clinton County; only a sliver of
its area reaches into Lycoming, so it is not counted on this page.

Townships

Lycoming County has 43 civil townships, more than all but a handful of Pennsylvania counties
— a reflection of how much rural, forested ground the county covers. Most are sparsely
settled; the eight below hold the bulk of the township population outside the boroughs.

Geography

Lycoming County is Pennsylvania’s largest county by land area, bigger than Rhode Island,
spanning the ridge-and-valley country of the state’s north-central region. Of its 1,244
square miles, 1,229 are land and 15 are water, about 1.2 percent. The West Branch Susquehanna
River runs the length of the county west to east through Williamsport, and Pine Creek cuts a deep
gorge, sometimes called the Pennsylvania Grand Canyon, through the county’s northwestern
corner. Two state forests, Tiadaghton and Loyalsock, and three state parks, Little Pine, Upper
Pine Bottom and Susquehanna, cover much of the county’s northern and western uplands.

Tioga County lies to the north, Bradford County to the northeast, Sullivan County to the east,
Columbia and Montour counties to the southeast, Northumberland County to the south, Union County
to the southwest, and Clinton and Potter counties to the west. Tioga County, Bradford County, Sullivan County, Columbia County, Montour County, Union County, Clinton County and Potter County all border Lycoming
directly; Northumberland County also borders it but has no page on this site yet.

Demographics

Lycoming County had a population of 114,188 at the 2020 census, and the latest estimate puts
the county near 112,587 residents, a gradual decline typical of rural Pennsylvania. Williamsport
and South Williamsport are the two largest communities, together holding roughly a third of the
county’s population. Median household income runs about $63,917 (2024 estimate), well below
Pennsylvania’s statewide figure of $73,824 (2023 ACS), and the county’s poverty rate
stood at 12.8 percent in 2024. Population density works out to roughly 93 people per square mile
of land, low for the region and a reflection of how much of the county is state forest.

Economy & Local Life

Health care and social assistance employs the most workers in the county, about 9,704 people,
followed by manufacturing at 7,143 and retail trade at 6,185, according to 2024 federal employment
data. UPMC Susquehanna, headquartered in Williamsport, is the county’s dominant hospital
system and health care employer. Pennsylvania College of Technology, a branch campus of Penn State University, anchors the city’s north side with several thousand students. Textron Lycoming
Engines, a maker of piston aircraft engines, and Brodart Company, a library-supply and furniture
manufacturer, both trace their roots to Williamsport’s 19th-century lumber wealth. The
county’s biggest annual event is the Little League World Series each August, played across
the river in South Williamsport at Howard J. Lamade Stadium and broadcast to audiences
worldwide.

History

Pennsylvania’s General Assembly formed Lycoming County on 13 April 1795 out of
Northumberland County, briefly weighing the name Jefferson County before settling on Lycoming,
after Lycoming Creek — itself the site of a pre-Revolutionary boundary dispute between
Native nations and colonial settlers. Williamsport was laid out in 1795, incorporated as a
borough in 1806, and became a city in 1866.

The county’s defining era was the lumber boom of the late 19th century, when
Williamsport’s sawmills and log booms on the West Branch Susquehanna River made it, for a
time, one of the wealthiest cities per capita in the country — the mansions built along West
Fourth Street earned the nickname Millionaires’ Row. The boom faded as the surrounding
timber ran out in the early 1900s, and the city’s population peaked at 45,729 in 1930. On 6
June 1939, Carl Stotz organized the first Little League Baseball game on a sandlot outside Bowman
Field in Williamsport, a local pastime that grew into the international youth baseball
organization still headquartered in the county today.

Getting There

Interstate 180 and US Route 220 cross the county’s southern half through Williamsport and
Loyalsock Township; US Route 15 runs north-south through Old Lycoming Township along the
Appalachian Thruway corridor. No interstate crosses the county’s northern half, which stays
reachable mainly by two-lane state routes through the Pine Creek and Loyalsock valleys.
