If the latest U.S. Census Bureau data are any indication, the Delaware River is the great divider between growth and decline in this region’s population.
More people are moving out of Warren and Hunterdon counties in New Jersey while more are moving into Northampton and Lehigh counties in Pennsylvania.
The Census Bureau this morning released county-by-county population estimates for last year. The data show both New Jersey counties lost population; both Pennsylvania counties gained population. This pattern has continued for three straight years, the data show.
Births outpaced deaths in all four counties; the population changes are instead tied to people migrating to or emigrating out of the counties, according to the census.
