There are some available data from Internet and history books. It may have reduced the world's population from 450 million to between 350 and 375 million. China lost around half of its population, from around 123 million to around 65 million; Europe around 1/3 of its population, from about 75 million to about 50 million; and Africa approximately 1/8 of its population, from around 80 million to 70 million (mortality rates tended to be correlated with population density so Africa, being less dense overall, had the lowest death rate). So, the total worldwide almost certainly reaches close to 100 million.
Due to the low level medicine and inadequate hygiene, being infected plague means to death. So many people were sapped by disease, or even inflicted to die that society certainly became into a mass. Corpses could be seen in streets, in turn bacterium spread fast. And due to a large number of death total, the laboring force was cut. So that many of the upper classes were forced to give higher wages and more freedom to their workers willing to work on the nobles' lands because of the high death toll. In its aftermath, the Black Death may also have favored the use of more advanced farming tools as a smaller workforce was available and plots grew larger as a result of the population loss.
