Outside Philly, suburban populations swell, census shows

From his shamrock-green stand in Concord Township, John Merion, 66, has seen his fields once redolent with cabbages and tomatoes sprout fancy homes, snazzy boutiques, and big-box stores.

Merion's Produce Hut, on Route 1 near Route 322, is all that remains of a family farm, begun in 1865 and sold to developers a century later.

With the transformation came a spike in population - from 11,239 residents in 2000 to 17,231 last year, according to U.S. Census figures released Wednesday.

Concord's 53.3 percent population increase over the decade was the highest in Delaware County, which grew 1.3 percent overall.

From Bucks County to the western reaches of Chester County, the suburban counties of Southeastern Pennsylvania joined in the swell.

Chester grew 15.1 percent, Montgomery 6.8 percent, and Bucks 4.6 percent.

Pennsylvania's overall population increased 3.4 percent, to 12,702,379, with the bulk of the growth concentrated in the southeast.

Counties in the western and north-central parts of the state largely lost population, with Allegheny County, home to Pittsburgh, shedding 4.6 percent of its people.

Upper Uwchlan, in Chester County, grew 63.9 percent, which township manager Cary Vargo attributed to its "central location" and easy access to the "employment centers" of Philadelphia, King of Prussia, Wilmington, and Allentown. That combination helped raise its population from 6,850 in 2000 to 11,227 last year.

In part, that growth was fueled by an increase in the township's Asian population. In 2000, Asians made up 1 percent of the municipality's population, according to the census. Now numbering 1,587, they are 14 percent.

Unlike the Census Bureau's annual estimates, which are sample-size surveys that include margins of error, the decennial census, mandated by Congress, attempts a complete count of the nation's population and its racial characteristics. The head count will be used to apportion U.S. House seats and redraw statehouse districts.

Diversity has contributed to the region's growth. Although the suburbs remain overwhelmingly white, the percentage of nonwhites was up in 97 percent of the region's municipalities.

In 2000, just 10 of the cities, townships, and boroughs were majority minority. Now, with the addition of Lansdowne, East Lansdowne, and Sharon Hill in Delaware County and Kennett Square in Chester County, 14 are majority minority.
