USA HISTORY

Detailed explanation-1: -“Cities grew because industrial factories required large workforces and workers and their families needed places to live near their jobs. Factories and cities attracted millions of immigrants looking for work and a better life in the United States.”

Detailed explanation-2: -The principal force driving America’s move into cities was the Second Industrial Revolution.

Detailed explanation-3: -Industrial expansion and population growth radically changed the face of the nation’s cities. Noise, traffic jams, slums, air pollution, and sanitation and health problems became commonplace. Mass transit, in the form of trolleys, cable cars, and subways, was built, and skyscrapers began to dominate city skylines.

Minorities and immigrants increased these numbers. Factory jobs were readily available for immigrants and as more came to the cities to work, the larger the cities became.
