Chino and its surroundings have long been a center of dairy farming, serving the considerable demands for milk products in Southern California and much of the southwestern United States. It is also well-known as the sites of three major California state prisons: the California Institution for Men, the California Institution for Women, and the California Youth Authority.
Beginning in the 1970s, it developed into a small suburban city, forming the western anchor of the Inland Empire region, and now the city's development has gradually taken on a more middle-class character. There are still many industrial areas as well as farm animals such as goats and chickens. According to the 2004 FBI UCR, the city had about 3.6 violent crimes per 1,000 population, which is typical for an American suburb, and its property crime was actually below average.
