One of the great magnets drawing Mexicans to metropolitan Atlanta was the region's development boom during the 1980s and 1990s. Accelerated by the selection of Atlanta to host the 1996 summer Olympic Games, the large expansion in construction activity drew many Mexican workers to the area. There is a growing presence of Mexican-Americans throughout the 10-county Atlanta region. But concentrations along the Buford Highway and I-85 corridor have expanded and now extend well into Gwinnett County.
