Main article: Demographics of the world One of the most obvious changes currently occurring is the change in the relative global population distribution between countries. In the recent decades, developing countries became a larger proportion of world population, increasing from 68% in 1950 to 82% in 2010, while population of the developed countries has declined from 32% of total world population in 1950 to 18% in 2010. China and India continue to be the largest countries, followed by the US as a distant third. However, population growth throughout the world is slowing. Population growth among developed countries has been slowing since the 1950s, and is now at 0.3% annual growth. Population growth among the less developed countries excluding the least developed has also been slowing, since 1960, and is now at 1.3% annual growth. Population growth among the least developed countries has not really slowed, and is the highest at 2.7% annual growth.[3]
