What do you know about population change in the English Middle Ages (c.1000-c.1500 AD)? Quite possibly, you have an inkling that the couple of centuries or so following the arrival of the Normans in 1066 were an era of steady growth in numbers. Almost certainly you know that that growth came to a juddering halt in the middle of the 14th century with the Black Death of 1348-9, and further outbreaks of plague and epidemic disease in the decades that followed.
