Most of the city is in Gwinnett County, which is part of the Atlanta-Sandy Springs-Marietta Metropolitan Statistical Area. The portions of the city in Hall County are not part of Atlanta's metropolitan statistical area, but are part of Atlanta's larger Combined Statistical Area, which includes Hall County.The city was founded in 1872 after a railroad was built in the area connecting Charlotte, North Carolina, with Atlanta. Buford was named after Algernon Sidney Buford, who at the time was president of the Atlanta and Richmond Air-Line Railway. The city's leather industry, led by the Bona Allen Company, as well as its location as a railway stop, caused the population to expand during the early 1900s until after the Great Depression had ended.
