How did the development of cities impact the growth of slums, rising crime statistics, and sanitation and health?

In the early part of US history, a majority of citizens lived in rural areas. Jobs were predominantly agriculture related. Beginning in the mid 1800s, industrialization caused cities to grow. The 19th and 20th centuries marked the Industrial Revolution. During this time, people moved to cities in multitudes. Cities offered many available jobs in factories, warehouses, and docks. The prospect of obtaining a higher standard of living (largely due to technological advancements) drew many people to urban areas.
The upper- and middle-class citizens began moving to the outskirts of cities away from all the factories in the center. This opened up opportunities for immigrants and newcomers to move in. Landlords took advantage of their desire to work in businesses nearby and offered low-rent apartments that were usually unsanitary and ill maintained.
The rapid growth of cities proved too much for local governments to keep up with. In poorer areas, clean water, sewage systems, and garbage collection were often neglected or overlooked. These overcrowded slums had miserable living conditions.
Large populations in concentrated areas allowed for the rapid spread of bacteria and disease. Since many slums lacked running water, toilets, and appropriate ventilation, personal hygiene was difficult to maintain. Infection and disease spread quickly from person to person.
With the growth in population, crime rates also increased. Crimes such as murder, robbery, theft, and prostitution became increasingly common in cities. Government officials and offices sometimes became corrupt, sometimes taking bribes.
