While Allegheny County is still the second oldest county in the U.S. in terms of residents' age, downtown Pittsburgh is bucking that trend.
According to the Census Bureau, about 17 percent (or 1 in 6) of the county's population is 65 years or older, but 27 percent of downtown Pittsburgh residents are under age 30. That's according to a new study by the Pittsburgh Downtown Partnership (PDP), which also found that 45 percent are under age 40.
A similar study in 2012 indicated 47 percent and 26 percent of downtown residents were under 40 and 30 respectively.
