Many of those who helped account for the population growth of cities were immigrants arriving from around the world. A steady stream of people from rural America also migrated to the cities during this period. Between 1880 and 1890, almost 40 percent of the townships in the United States lost population because of migration. <span>uring the final years of the 1800s, industrial cities, with all the problems brought on by rapid population growth and lack of infrastructure to support the growth, occupied a special place in U.S. history. For all the problems, and there were many, the cities promoted a special bond between people and laid the foundation for the multiethnic, multicultural society that we cherish today.
