How did population growth contributed to the industrial growth?

Answer 1

In a nut shell because more things could be manufactured in a quicker time that before. Food was one of them which led to the population rising.

Domestic Industry preceded the industrial revolution. Domestic industry was when individual households did their own manufacture of wares which they then sold on. It was usually a heridary trade passed from generation to generation and had lasted for hundreds of years. Domestic industry was very labour intensive in that it required alot of direct human input to produce the goods in question.

The industrial revolution was marked by the introduction of machinery and technologies which could do the work of several people in a much shorter time. This begin to apply to all walks of industry - agriculture, textiles etc. As the industrial revolution gained pace more and more people found it harder to get employment in rural areas and moved to inner cities were people were required to operate the machinery. In turn mining also became a hugh industry as more resources were needed to service and build the machines.

The recurring effect of all this was that larger outputs helped service the growing population which in turn got employed in mills, factories etc which then led to greater outputs - leading to greater population etc etc etc.
