Lancaster County population tops half a million

New data out today from the U.S. Census Bureau indicates that Lancaster County’s population officially topped the half-million mark last year. The county grew by 4,415 between July 2007 and July 2008, bumping it from 497,955 residents in 2007 to 502,370 in 2008. The increase is 0.9 percent in one year.

From 2000 to 2008, Lancaster County has grown 6.7 percent. During that time period, Chester (13.4 percent) and York (11.2 percent) were the only Pennsylvania counties to grow faster.

Lancaster’s growth rate this decade has been higher than predicted. The Pennsylvania State Data Center projected Lancaster County’s 2010 population would be just 498,465. New data certainly calls into question the Data Center’s projections for Lancaster County in 2020 (pop. 526,194) and 2030 (pop. 553,293). Is it possible that the county will top 600,000 in the next decade?
