They are the states that have the highest population of residents, aged 65 or older, as this “map of the month” from the Pennsylvania State Data Center shows. For each one of them, the population 65 and over represents more than 17 percent of the total, compared to around 10 percent for states like Alaska and Utah. According to a recent issue brief from the center, the number of older people in Pennsylvania grew 10 percent between 2011 and 2015, while the general population rose 0.5 percent.
