Conshohocken, PA: Population, Cost of Living, and Flood Risk on the Schuylkill

Where Conshohocken Is, and Why Searches Add “United States”

A one-square-mile borough on the Schuylkill River in Montgomery County anchors this part of Philadelphia’s northwest suburbs, with 9,282 residents as of the 2024 American Community Survey five-year estimates. A search that appends “united states” to the town name usually means one of two things: confirming this isn’t a place with the same name elsewhere, or sorting out its relationship to West Conshohocken, a separate, much smaller borough directly across the river with its own municipal government and a 2024-estimate population of 1,536 residents. The two share a name and a bridge, not a government, a school district, or a set of statistics: Conshohocken’s population figures, tax base, and zoning decisions are entirely its own.

Is Conshohocken part of Philadelphia? No. It’s an independent borough in Montgomery County, roughly 10 miles from the Philadelphia city line, with its own borough government, police department, and tax structure.

Is West Conshohocken the same place? No. It’s a separate borough on the opposite riverbank, with about one-sixth of Conshohocken’s population and its own local government.

Population and Income: A 2021 Peak, Then a Plateau

The population trend is not a straight climb. U.S. Census Bureau Population Estimates put Conshohocken at 9,276 in 2021, its high point across the two decades of available estimates, before edging down to 9,256 by 2023, according to a compilation of the Census Bureau’s Population Estimates Program. The 2024 American Community Survey five-year estimate lands at 9,282, and a private demographic firm’s 2025 projection puts it at 9,391: sources disagree on the direction of the last few years, which matters more than a single static figure would suggest.

The 2021 dip-then-plateau lines up with a labor-market shift the same data source shows locally: employment among Conshohocken residents fell from about 6,600 to 6,550 between 2023 and 2024, a 0.79% year-over-year drop, even as median household income rose 4.6% to $122,721, per Data USA’s 2024 profile. Income and headcount are moving in different directions at once.

Cost of Living: Conshohocken vs. Philadelphia

Median figures for Conshohocken are often quoted alone. Set beside the city it borders, the gap is large enough to change a relocation decision, not just describe one.

The income rows use different ACS vintages, five-year for Conshohocken and one-year for Philadelphia, because that’s what each place’s current Census Reporter profile publishes; read the ratio as directional. Even allowing for that, a Conshohocken household earns roughly twice the citywide median while commuting a few minutes less: the trade is a smaller, denser town at a materially higher price per square foot of housing.

Flood Risk on the Riverfront

Conshohocken’s riverfront section is not a hypothetical flood zone. On September 1–2, 2021, the remnants of Hurricane Ida sent the Schuylkill River over its banks; Philadelphia’s Fire Commissioner said at the time that the river hadn’t flooded that severely since 1869. A peer-reviewed U.S. Geological Survey analysis of the event found new peak-streamflow records at 19 of 52 Pennsylvania streamgages studied, with some Schuylkill-basin readings corresponding to a recurrence interval of 500 years or longer.

Locally, the damage pattern was uneven. Riverfront office and apartment buildings built over the prior three decades were designed to let floodwater pass through ground-floor lobbies and parking areas, and largely performed as intended, according to local reporting from the borough’s own news outlet; water still rose above the railroad tracks for the first time in recent memory, damaging small businesses on East Elm Street and destroying the Borough’s riverside dog park.

No deaths or major injuries were reported in Conshohocken itself. In the aftermath, the Borough purchased a high-water rescue vehicle, and its Council voted to stop permitting additional residential construction along the riverfront.

Did Conshohocken flood in 2021? Yes. The Schuylkill River rose to record or near-record levels on September 1–2, 2021, flooding parts of the riverfront and damaging several downtown businesses; no deaths were reported locally.

Jobs: the Companies Headquartered Here

More than 2,900 extra people move through Conshohocken on an average workday through commuting, and the reason sits mostly in two buildings. Cencora, the pharmaceutical distribution company known until 2023 as AmerisourceBergen (it changed its name and NYSE ticker to COR that year, per its own SEC filing), opened its 429,000-square-foot global headquarters at SORA West on September 28, 2021, a Gensler-designed building that anchors a mixed-use development with a 127-room hotel and a 1,500-space garage, according to the company’s own ribbon-cutting announcement; roughly 1,400 associates work from the site, per the building contractor’s project page. A few blocks away, Quaker Houghton, a metalworking-fluids manufacturer, keeps its corporate headquarters and a laboratory facility in Conshohocken, confirmed in its parent company’s annual SEC filings going back decades.

The residents’ side of the job market looks different from the employers’ side: the most common industries for people who live in Conshohocken, whether or not they work there, are health care and social assistance, professional and technical services, and finance and insurance, together accounting for over 2,700 jobs among local residents, per Data USA.

Getting Around: Trains, the Curve, and Parking Downtown

Fifteen Regional Rail stations make up SEPTA’s Manayunk/Norristown Line along the Schuylkill River, including a stop in downtown Conshohocken, with a designated quiet car on weekday trains carrying three or more cars between 4 a.m. and 7 p.m., per the line’s current published schedule. The Schuylkill Expressway (I-76) bends sharply where it hugs the river here, a curve regional traffic reports refer to as “the Conshohocken curve,” a recurring congestion point for anyone driving in rather than taking the train.

Parking downtown is metered, not open lot by default. The Borough runs about 150 on-street metered spaces through the Parkmobile app, per its own parking page, plus two garages: the SORA West garage, where the first two levels (150 spaces) are open to the public weekdays 7 a.m. to 5 p.m. and weekends 9 a.m. to 2 a.m., while all 850 spaces open evenings and weekends; and the Two Tower Bridge garage, with metered parking on its top deck weekdays 9 a.m. to 6 p.m. A residential parking permit costs a one-time $15 fee under the Borough’s municipal code, but still caps parking at two hours in metered zones: the permit exempts a resident from meter payment, not from the time limit.

From Mill Town to Riverfront Hub

Conshohocken grew up as a Schuylkill River mill town, its economy tied to the industries that lined the water. As manufacturing declined through the twentieth century, the same riverfront land was rebuilt over roughly the past thirty years into the office towers, apartments, and hotels that define the borough today.

Livability Grades: What They Measure and What They Don’t

A composite score of A+ and a #9 ranking among places to live in Pennsylvania for 2026 come from Niche.com, which says it draws on Census, FBI, and Bureau of Labor Statistics data blended with its own review data and a weighting formula it doesn’t publish in full. That’s a different kind of evidence than a Census table: useful for comparing towns on the same scale, not verifiable line by line the way an ACS income figure is.

Is Conshohocken a good place to live? By Niche’s proprietary ranking, yes: it’s graded A+ and ranked #9 in Pennsylvania for 2026. Judge that grade as one input, not a substitute for the income, cost, and flood-risk figures above.
