The Bucks County Courthouse, established in 1663[citation needed], is said to have been located in Fallsington until it was moved to Bristol in 1705.

Also in 1690, Thomas Janney donated 72 acres (0.29 km2) of land to be used as the Quaker burial grounds for Falls Monthly Meeting.

Villages and other place names, past and present, include Dogtown, Fairless Hills, Fallsington, Kildorpy, Kirkbridesville, Levittown, Morningside, Oxford Valley (located in both Falls Township and Middletown Township, Penns Manor, Penn Valley, Slickville, Tyburn, and Wheatsheaf.

[3] The growth of Fallsington continued, with the construction of homes, an inn, public buildings, stores, and small craftsmen's shops.

Until the construction of Fairless Hills and Levittown, it was the largest village in the township, and functioned for many years as a commercial center.

The 8,431-acre (34.12 km2) site in Falls Township was chosen for its easy access to Philadelphia along the Delaware River.

In 1932, a small portion of the original site was purchased by Pennsylvania and reconstruction of Pennsbury Manor was begun.

In 1686, the Provincial Council ordered the construction of the King's Highway, which ran from Philadelphia to Trenton along an existing Indian trail, through Bristol, Falls, and Morrisville.

The King's Highway still exists today as U.S. Route 13, flowing closely the original configuration.

The "West Trenton" cut-off of the Pennsylvania Railroad was built through the northern part of the township at the end of 19th century.

These rail lines now accommodate SEPTA, Amtrak and Conrail passenger and freight between Philadelphia and Trenton.

4.4% of the population were of Hispanic or Latino ancestry[7] As of the census[8] of 2000, there were 34,865 people, 13,170 households, and 9,403 families residing in the township.

Pennsylvania Route 32 begins at the US 1 freeway in the northeastern section of the township, heading northeastward along Bridge Street.

Amtrak's Northeast Corridor and SEPTA Regional Rail's Trenton Line pass through the township but do not have any stations within it.

Ice storms and large snowstorms depositing ≥ 12 inches (30 cm) occur once every few years, particularly during nor’easters from December through February.
