Final answer:
The 13 colonies experienced considerable population and economic growth between 1700 and 1775, with the middle colonies displaying substantial ethnic, religious, and economic diversity.
Step-by-step explanation:
Between 1700 and 1775, the 13 colonies experienced significant population growth. This expansion was driven by both a high birth rate and waves of immigrants who contributed to the formation of a near-continuous zone of settlement along the Atlantic coast. The growth in population facilitated increased economic growth, as the expansion of the British Empire's commercial interests led to the implementation of mercantilist policies. These propelled the colonial economy forward through increased production of raw materials exchanged for British manufactured goods, raising the colonies' standard of living. Moreover, the middle colonies were characterized by ethnic, religious, and economic diversity, with the middle colonies having a robust economy fueled by commercial trade and the growth of towns and cities. This diversity and economic vitality were indicators of the overall growth the colonies underwent during this period.
