USA HISTORY

Detailed explanation-1: -The technological explosion that was the Industrial Revolution led to a momentous increase in the process of urbanization. Larger populations in small areas meant that the new factories could draw on a big pool of workers and that the larger labour force could be ever more specialized.

Detailed explanation-2: -The process of industrialization had begun, bringing about profound changes over the lives of humans and their interactions with the natural world. With improved living standard, lowered death rate and prolonged life expectancy, human population grew exponentially.

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.

Detailed explanation-4: -With the Industrial Revolution gathering steam, the global population growth rate jumped from around 0.02% per year in the early 1400s to 0.23% in 1600 and then 0.33% in the mid-1700s. By 1970, it peaked at about 2% per year, and began its return to the norm.
