All the estimates for the post-1348 decline are highly conjectural: the first epidemic is variously estimated to have killed a fifth, a quarter or a third or more Europe-wide: other outbreaks followed for centuries, but the population is thought to have reached its nadir in the late 15th century. One problem is that population tended to recover between epidemics, only to be cut back again. England is reckoned by some to have lost a half of its population over the whole period; some areas of Europe suffered far less. The total may have fallen from 80 million to 55m by the 1470s, with the biggest drop in 1348-53.

The Black Death.
Black Death almost killed half of Europe's population. It broke Europe economically and socially.
You were very probably given choices to pick from that you do not tell us about. A thousand things are unrelated to the Black Death, so we need the options you were given.
Black Death killed 75 to 200 million people. Population decreased by 30-60%.
Bubonic Plague (Black Plague) or (Black Death)
the Black Death was very deadly. it killed 75 to 200 million people.
Weakened power of the church, increased power of the king, 1/3 population died, Fuedalism was weakened.
Population of the world would have been much more. European countries would have been still under church's control.
The black death wiped out huge swaths of the European population. As a result the supply of workers was low. When supply is low and demand is high, prices go up. Demand was also diminished (fewer mouths to feed) but not so much as supply, as certain sectors of the population were harder hit, especially the poor- i.e. peasants and serfs. As a result, surviving workers were able to charge more for the services. In the long term, the black death spelled the end of serfdom and paved the way for a stronger and larger middle class.
The Crusades and the Inventing of the Printing Press. Additionally, the population losses sustained in Europe as a result of the Black Death made it necessary to invent new devices to save human labor.
