Because of an already high population.
World War II led to one of the largest population shifts in U.S. history due to a combination of factors, including the migration of millions to urban areas for war-related jobs and the movement of African Americans from the South to Northern cities during the Great Migration. Additionally, returning soldiers after the war contributed to suburban expansion, as they sought affordable housing and new opportunities. The post-war economic boom also encouraged internal migration, reshaping demographics and driving growth in various regions across the country.
The Great Migration was the movement of 6 million African Americans out of the rural Southern United States to the Northeast, Midwest, and West from 1910 to 1970. Some historians differentiate between the first Great Migration (1910-1930), numbering about 1.6 million migrants who left mostly rural areas to migrate to northern and midwestern industrial cities, and, after a lull during the Great Depression, a Second Great Migration (1940 to 1970), in which 5 million or more people moved, including many to California and various western cities. i got it from wikipedia

The Great Migration during World War I was a significant movement of African Americans from the rural South to urban areas in the North and West, primarily between 1916 and 1970. Driven by the search for better economic opportunities, escape from Jim Crow segregation, and the demand for labor in factories due to the war, millions relocated to cities like Chicago, Detroit, and New York. This migration not only transformed the demographics of these urban centers but also had a profound impact on cultural expressions, laying the groundwork for the Harlem Renaissance and advancing the civil rights movement.
The Great Migration occurred during World War I as African Americans sought better economic opportunities and escape from the oppressive conditions of the Jim Crow South. The war created a labor shortage in northern industrial cities, prompting factories to recruit workers from the South. This movement allowed many African Americans to find jobs in industries such as steel, meatpacking, and munitions, leading to a demographic shift and significant cultural changes in urban areas. The migration also laid the groundwork for the civil rights movements that would follow in subsequent decades.
Overcrowding: Migration into urban areas can lead to overcrowding, putting a strain on infrastructure and services. Unemployment: Large influxes of migrants can contribute to high unemployment rates in urban areas. Social issues: Increased migration can lead to social issues such as poverty, crime, and inequality, which the government may seek to mitigate.
To alleviate overcrowding in urban areas, reducing strain on infrastructure and services. To prevent rural-to-urban migration that may lead to a concentration of resources and wealth in a few areas, worsening regional disparities. To preserve traditional rural communities and livelihoods, and maintain a balance between urban and rural development.
Governments may discourage migration to urban areas due to concerns related to overpopulation, strain on infrastructure, increased demand for public services, and escalating cost of living. Additionally, promoting balanced development across regions and preventing urban sprawl are common reasons for encouraging population distribution to rural areas.
Internal migration is movement within a country. For example, moving from the East Coast of the US to the West Coast.International migration is moving from one country to another. For example moving from China to America.

More population lives in rural areas but city population is increasing due to migration .
It is to ease traffic congestion at crowded areas such as downtown areas in a country. It will discourage motorists from driving to that area as they have to pay once they enter through a certain road around the area.
People moving from rural (villages) areas of the country into cities. :)
Pluralism
They don't control any areas anymore. Government have eradicated them from the country.
