The demographics of the Cucamonga Valley have been shifting in recent years. The population of European Americans, who once constituted a large majority, is on the decline while the population of Latinos and African Americans is growing.

Many of the existing freeways in Southern California's Inland Empire were completed in the late 1970s. The only exception is the segment of the Foothill Freeway, State Route 210 between San Dimas and San Bernardino, completed in July 2007. In general, most of the higher paying jobs are located in Los Angeles and Orange County. Thus, workers must commute daily up to two hours in each direction on the existing network. As the population increases, traffic congestion is projected to increase as well. In 2007, Forbes magazine ranked the area first in its list of America's most unhealthy commutes, beating every other major metropolitan area in the country, as Inland area drivers breathe the unhealthiest air and have the highest rate of fatal auto accidents per capita.
The Inland Empire (IE) is a metropolitan area and region inland of and adjacent to coastal Southern California, centering around the cities of San Bernardino and Riverside, and borders Los Angeles County to the west. It includes the cities of western Riverside County and southwestern San Bernardino County, and is considered to include the desert communities of the Coachella and Victor Valleys, respectively on the other sides of the San Gorgonio Pass and San Bernardino Mountains from the Santa Ana River watershed that forms the bulk of the Inland Empire; a much broader definition includes all of Riverside and San Bernardino counties. The combined land area of the counties of the Inland Empire is larger than ten U.S. states – West Virginia, Maryland, Hawaii, Massachusetts, Vermont, New Hampshire, New Jersey, Connecticut, Delaware and Rhode Island – and is slightly smaller than the combined area of the last five.
