Fukuoka City's future population projection anticipates the city's population peaking at approximately 1,702,000 by 2040. The 2012 projection estimated the peak at about 1,606,000 by 2035. However, as of December 2023, the population already exceeded this figure, reaching 1,644,734. The continued influx of younger generations from various prefectures in Kyushu is expected to drive population growth for an additional five years.
