Clayton County will add another 119,000 residents by the year 2050, according to population estimates from the Atlanta Regional Commission.

The southside community will grow to a population of 393,000 citizens by mid-century, the ARC predicts. Of the residents, 60 percent will be black by 2050, with hispanic and other non-white residents comprising 27 percent and 11 percent of the population respectively.

The share of residents age 75 or older will reach more than 8 percent in 2050, compared to 3 percent in 2015, the ARC estimates.

The changes in Clayton come as the 21-county Atlanta region is expected to add 2.9 million people by 2050, pushing the total population to 8.6 million, the ARC said.
