Thus, the major population challenge is to meet the human needs of 2.1 billion more people, house and employ 4 billion new urban residents, while limiting the environmentally damaging impacts of such growth and urbanization. At the same time, the continued global fertility decline leads to an increasing ageing of the population. A growing population need is to care for ageing populations in industrialized and newly industrializing countries and to absorb the migrants those societies will require.
1.2.2 Health and well-being
The overall health of people has substantially improved over the last sixty years. The average life expectancy for a newborn child has been extended from 46 to 69 years. Much of this improvement is from reductions in infant and child mortality for which immunization, and improved water, sanitation, and nutrition have played major roles. But major health problems persist with the spread of infectious diseases, characteristic of developing countries, and the chronic diseases of industrialized countries.
