Final answer:
The increase of migration to England between 1700-1800 was mainly due to industrialization which attracted people to urban centers, displacement from rural areas by enclosure movements, and opportunities arising from the expansion of the British Empire.
Step-by-step explanation:
The increase of migration to England from 1700-1800 can be attributed to several factors including industrialization, changes in agricultural practices, and the expansion of the British Empire. The industrial revolution caused a massive rural-to-urban shift, drawing people to urban centers in England such as the Midlands of northern England. People were displaced from agricultural lands due to enclosure movements which converted arable lands to pastures for livestock, leading to an increase in landless, jobless peasants.
Additionally, England's expansion as a commercial and military powerhouse provided opportunities both in trade and in the form of new colonies, where English migrants could escape overcrowding and poverty. Finally, the need for labor in industrial centers and urban areas due to factories, mines, and other industrial works led to a significant influx of migrants looking for work.
The changes in population distribution during this period were also significant, as communities grew around areas that were conducive to the establishment of factories, such as those with easy access to water and natural resources. Moreover, the British colonial empire influenced migration patterns, with people moving from colonies to the home country. This included both voluntary migrants such as skilled workers and those affected by factors such as overcrowding, poverty, and political unrest in their home countries or colonies.
