Population changes can have significant effects on both more economically developed and less economically developed countries. In LEDCs, high population growth rates can outstrip resources and lead to problems like food and water shortages, malnutrition, rapid urbanization, and lack of adequate healthcare and education. MEDCs with declining growth rates may have issues supporting aging populations with fewer working-age people and more elderly dependents requiring services like healthcare and pensions. Kenya faces challenges from its AIDS pandemic, which costs over $1.8 million per day and leaves many unable to afford treatment, contributing to higher mortality rates and lower life expectancy.
