life+expectancy+rates

During the period of the Industrial Revolution, life expectancy rates became much higher. This was due to a number of things. Machines made less hard work for people, so they wern't as broken up. A greater sense of hygiene reduced the number of germs. Vaccines were also being found by doctors during the scientific revolution. The invention of the smallpox vaccine, by Edward Jenner, greatly decreased the number of deaths by smallpox. Because the life expectancy rate went up, the poulation also began to go up. A higher life expectancy rate can account for a portion of the population boom during this time.
