In what ways did the industrial revolution encourage an increase in overall world population?

Great Britain led the world in industrializing, but before the industrial revolution fully took off, the country underwent an agricultural revolution that lifted crop yields and improved livestock. This made it possible to support a rapidly growing population.

Industrialism led to earlier marriages and a consequent spike in births. Because people could earn more money and the cost of goods was falling—when a factory can produce a hundred or a thousand times more of a product than can be made by hand, prices tend to fall—it became possible for more and more people to marry earlier. Further, because of improvements in health and diet, more women were able to get pregnant; The number of births out of wedlock grew significantly.

Further, something as simple as an extra layer of protection—provided by being able to afford underwear, decent coats, and shoes—made it possible for more people to stay alive longer.

Between 1750 and 1850, the period of rapid industrialism that contributed to making England the premier world power, the population of the country doubled.
