The correct option is D. Construction of modern multi-lane roads was one essential factor in the development of suburbs in the 1950s. By enabling affluent white families to maintain their jobs in the inner city while not being required to reside there, the expansion of highways and the availability of more cheap cars contributed to the spread of suburbs. Now they could commute to work from nicer, safer neighborhoods outside of the city.
Why are suburbs growing?
In 60% of all metro regions, growth in suburbs is outpacing growth in cities. Due to their desire for larger homes and amenities like decent schools as they approach life milestones like marriage and parenthood, the Millennial generation is helping to fuel this trend.
Several historical factors, such as the social effects of the Great Depression, the widespread demobilization following World War II, increased government involvement in housing and development, the mass marketing of the automobile, and a significant shift in demographics all contributed to the growth of suburbs.
