WORLD VIEW: As the population increased, changes in agriculture and industry led to the rapid growth of cities. Employment on farms declined as developing industries in or near cities offered new jobs. The factory system became the greatest cause of city growth. By the early 1900s, more people lived in or near cities than in the countryside. No city in the United States had a population of 1 million in 1800. Yet just 100 years later, cities such as New York, Chicago, and Philadelphia each had more than 1 million residents. Cleveland later experienced a growth from 381,768 residents in 1900 to 878,336 residents in 1940.
