The main causes of urban problems include unemployment, rural-urban migration and the embezzlement of funds. These issues lead to different problems in one way or another.
High rates of unemployment in urban areas lead to increased crime rates, illegal drug use due to idleness, prostitution and the formation of illegal gangs. Immigration of people from rural areas to urban areas creates a strain on the available resources. It also contributes to unpleasant demographic results. In some countries, rural-urban migration has contributed to a high growth rate of slums. It also led to an increase in pollution, which poses risks to the health of people within such environments.
