The correct answer is “the growth of suburbs and the increased affordability of cars”
After the war, the US manufacturing economy changed from war-related items to consumer goods, including cars. By the end of the 1950’s, there were more than 6.7 million cars registered in the US - it more than doubled since the beginning of the decade. Land developers began to sell land outside the cities limits and with investment in highways and bridges suburbs grew rapidly.
By the early 1870s, the system known as sharecropping had come to dominate agriculture across the cotton-planting South. Under this system, black families would rent small plots of land, or shares, to work themselves; in return, they would give a portion of their crop to the landowner at the end of the year.
