In 1920, the ratio of the urban and rural population was in 51:49. The population of the United States remained approximately the same in both region. The rural population moved to the urban for jobs and to live in a better condition than in rural. The standards of living were different between the city and the country. Rural areas were without electricity, where 50 per cent of urban homes had electricity. Life was getting easier in the city. Electricity opened the door for small appliances and washing machine.
The 1920 United States census recorded that 51.2% of the population was living in urban areas. Since the census is taken only every ten years, we don't really have great data for the years in between, so 1920 is the closest we have to a year where the urban/rural split was roughly 50/50.
