Final answer:
The population in the English colonies grew substantially by the 1750s due to economic opportunities, forced slavery, the pursuit of religious freedom, and the chance for self-government and land ownership.
Step-by-step explanation:
Factors Contributing to the Population Growth in English Colonies
By the 1750s, the population in the English colonies had grown tremendously due to several key factors. One of the primary reasons was the economic opportunities that the colonies presented, with the mercantilist system helping to create a favorable environment for trade and business development. Furthermore, many individuals were forced into slavery and brought to the colonies to work in the fields, significantly increasing the population. The offer of religious freedom also attracted many settlers, especially pious Puritan families who established colonies in New England to practice their beliefs without persecution. Additionally, the possibility of self-government and owning land was also an attractive prospect for those who faced limited prospects in England. The colonies provided space for people to establish themselves economically and politically in ways that could not be done in the overcrowded homeland.
