Cite examples of changes brought about by a shift from rural to urban living.

As populations transition from rural to urban living, many social changes take place. Although these can change depending on the time and place, some of them are common to all populations.

For example, as people move to urban environments, they tend to live in closer proximity to each other. This presents problems when it comes to sanitation and higiene. In turn, this can increase the risk for epidemics.

Another example of such changes is the fact that housing in cities tends to be smaller and more expensive than housing in rural areas. This affects families in various ways, such as increasing the number of poor people or encouraging smaller families.
