Answer:
housing shortages
Step-by-step explanation:
The housing shortages and the rapid urbanization go hand by hand. When people move in big numbers toward certain place, usually a larger city, in order to have a better life, they are actually surplus when taken in consideration the amount of people the city can accommodate. This results in housing shortage, and the demand for flats and houses skyrockets. Because of this, rapid urbanization takes place so that the demand is satisfied, so the city expands very quickly. A problem that often occurs with the rapid urbanization though is that it is not usually wall planned, performed in a rush, and the housing is not of good quality.
