The world population grew from 1 billion to 7 billion from 1800 to 2011.

During the early 1600s in England, life expectancy was only about 35 years, largely because two-thirds of all children died before the age of four. The average life expectancy in Colonial America was under 25 years in the Virginia colony, and in New England about 40% of children failed to reach adulthood. During the Industrial Revolution, the life expectancy of children increased
tically. The percentage of children born in London who died before the age of five decreased from 74.5% in 1730-1749 to 31.8% in 1810-1829.
