During the early 17th century in England, average life expectancy was only about 35 years, largely because two-thirds of all children died before the age of four.[13] During the Industrial Revolution, the life expectancy of children increased dramatically.[14] According to population health experts, child mortality rates have fallen sharply since the 1990s. Deaths of children under the age of five are down by 42% in the United States, while Serbia and Malaysia have cut their rates by nearly 70%.[15] |
