Macon /ˈmeɪkən/ (officially Macon–Bibb County) is a city located in the state of Georgia, United States. Macon lies near the geographic center of the state, approximately 85 miles (137 km) south of Atlanta, hence the city's nickname "the Heart of Georgia."
Settled near the fall line of the Ocmulgee River, Macon is the county seat of Bibb County and had a 2014 estimated population of 153,691. Macon is the principal city of the Macon metropolitan area, which had an estimated population of 231,259 in 2014. Macon is also the largest city in the Macon–Warner Robins Combined Statistical Area (CSA), a larger trading area with an estimated 417,473 residents in 2014; the CSA abuts the Atlanta metropolitan area just to the north.
In a 2012 referendum, voters approved the consolidation of Macon and Bibb County, and Macon became Georgia's fourth-largest city (just after Augusta). The two governments officially merged on January 1, 2014.
