The state of public health is considerably better in the cities. Birth rates, infant mortality rates, and death rates are lower in cities than in rural areas due to better access to education, medicines, and hospitals. Life expectancy is better in cities compared to rural areas, but there have been significant improvements witnessed throughout the country in recent years, the average Ethiopian living to be 62.2 years old, according to a UNDP report. Despite sanitation being a problem, use of improved water sources is also on the rise; 81% in cities compared to 11% in rural areas. As in other parts of Africa, there has been a steady migration of people towards the cities in hopes of better living conditions.
