Answer:
The industrialization in the US in the late 1800s resulted in an increase in urbanization.
Step-by-step explanation:
The United States, as most of the countries in the world, had a population that was mostly rural, with the majority of the population being engaged in agricultural production. During the late 1800s, this situation started to rapidly change, and the reason was the fast industrialization of the country. Thousands of industrial facilities were built in the United States in a short period of time and their number was constantly growing over the coming period.
With such a rapidly growing industry, the need for a labor force was sharply on the rise, so the governing bodies and the companies themselves were trying to motivate the people to come and work there. Most of the people didn't really think twice when given the option to escape from the agricultural fields and work in factories, so millions of people flocked to the cities where the industry was located. With so many people coming into the cities, there was an increased demand for housing, so rapid urbanization took off, and soon huge urban areas were created around the industrial centers.
