What were the causes of urban growth in the late 1800's?

Urbanization means the redistribution of populations from rural (farming or country life) to urban (town and city) life. Urbanization in America saw the emergence of many new towns and cities which became even larger as more and more people, attracted by employment possibilities, begin living and working in towns and cities. During this period in American history workers moved towards manufacturing centers in cities and towns seeking jobs in factories as agricultural jobs became less common. Urbanization in America in the late 1800's was also driven by the massive influx of unskilled immigrants who also flocked to the industrial cities to start their new life in America, the land of opportunity.
