Mass transportation revised the social andeconomic fabric of the American city in threefundamental ways. It catalyzed physicalexpansion, it sorted out people and land uses, andit accelerated the inherent instability of urban life. By opening vast areas of unoccupied land forresidential expansion, the omnibuses, horserailways, commuter trains, and electric trolleys pulled settled regions outward two to fourtimes more distant form city centers than they were in the premodern era. In 1850, forexample, the borders of Boston lay scarcely two miles from the old business district; by theturn of the century the radius extended ten miles. Now those who could afford it could live farremoved from the old city center and still commute there for work, shopping, andentertainment. The new accessibility of land around the periphery of almost every major citysparked an explosion of real estate development and fueled what we now know as urbansprawl. Between 1890 and 1920, for example, some 250,000 new residential lots were recordedwithin the borders of Chicago, most of them located in outlying areas. Over the same period, another 550,000 were plotted outside the city limits but within the metropolitan area. Anxiousto take advantage of the possibilities of commuting, real estate developers added 800,000 potential building sites to the Chicago region in just thirty years – lots that could have housedfive to six million people.

Of course, many were never occupied; there was always a huge surplus of subdivided, but vacant, land around Chicago and other cities. These excesses underscore a feature ofresidential expansion related to the growth of mass transportation: urban sprawl wasessentially unplanned. It was carried out by thousands of small investors who paid littleheed to coordinated land use or to future land users. Those who purchased and prepared landfor residential purposes, particularly land near or outside city borders where transit lines andmiddle-class inhabitants were anticipated, did so to create demand as much as to respond toit. Chicago is a prime example of this process. Real estate subdivision there proceeded muchfaster than population growth.
