Life expectancy in the world’s high-income countries is now 78 years, while it is only 51 years in the least-developed countries, and as low as 40 years in some AIDS-ridden African countries. For every 1,000 children born in rich countries, seven die before their fifth birthday; for every 1,000 births in the poorest countries, 155 children die before their fifth birthday.
