I hope this is the answer you are searching for. I found it in wikipedia under the heading of Black Death.
The Black Death is estimated to have killed 30% to 60% of Europe's population, reducing the world's population from an estimated 450 million to between 350 and 375 million in 1400. This has been seen as creating a series of religious, social and economic upheavals which had profound effects on the course of European history. It took 150 years for Europe's population to recover. The plague returned at various times, resulting in a larger number of deaths, until it left Europe in the 19th century.

The fourteenth century in Europe did not differ demographically from the High Middle Ages much. The large-scale migration of peoples all over Europe had mostly happened between 400 and 800 AD . The later Viking migrations into England, Russia and Sicily had happened in the centuries thereafter, but by the 13th century big demographic shifts had become a thing of the past. The only very notable change was that the 14th century had seen the second Great Plague, also known as the Black Death, that killed between 50 and 70% of Europe's population.
