Between 1551 and 1801 the population of London grew from 80,000 to 865,000. This was despite the fact that during this period overall deaths exceeded births in the capital.  This can partly be seen as London attracting migrants with energy and ideas, but can also be seen as people moving from the countryside because they had no choice, with traditional industries such as agriculture, spinning and weaving being hollowed out by mechanisation.
