The dramatic results of this report by authors Roy Beck and Leon Kolankiewicz indicate that population growth has been the No. 1 factor in California's relentless urban sprawl. Overall, 95% of the total sprawl in California from 1970-1990 was related to population growth., indicating that most Urbanized Areas in California succeed in stopping increases in per capita land consumption. Yet despite efforts to stop per capita land consumption, sprawl consumed another 1,670 square miles of land during the period studied, primarily because of population growth. "Sprawl in California" was presented at the CAPS 2000 Conference at the University of Southern California on August 13, 2000.
