The main economic activities of the city is commerce and agriculture, although the economy is shifting away from agriculture. Commerce, including tourism, is mostly concentrated in the city proper, while agriculture and certain industries such as brick making, are mostly found in the edge of the city and in the rural areas of the municipalities of San Pedro Cholula and San Andrés Cholula. Despite being a city in its own right, Cholula is part of the Puebla metropolitan area, with residential areas encroaching onto former farmland.
