The town experienced its first growth spurt during the last decade of the 19th century (as did many of the surrounding communities), thanks to ever-increasing demands for California-grown citrus fruits, a period some refer to as the "Orange Era." Southern California's real estate "boom" of 1886–1888, fueled by railroad rate wars, also contributed to a marked increase in population. Like most cities in Orange County, agriculture formed the backbone of the local economy, and growth thereafter was slow and steady until the 1950s, when a second real estate boom spurred development. Inspired by the development of a region-wide freeway system which connected Los Angeles' urban center with outlying areas like Orange, large tracts of housing were developed from the 1950s to the early 1970s, and this continues today, albeit at a much slower pace, at the eastern edge of the city.
