According to preliminary reports [pdf] from the Pennsylvania Department of Health, 7,229 babies were born in Lancaster County in 2008. Only Philadelphia County, Allegheny County, and Montgomery County had more. There were a total of 148,927 births in PA last year, which means that five percent of children born in Pennsylvania last year were born in Lancaster County. August was the month with the most births (677), which I suppose means parents were feeling both festive and pent-up in December 2007.
Here’s a snapshot of the trending of Lancaster County births since 1994.
