The plague caused a drastic decrease in population numbers. This deadly disease took the lives of nearly one quarter of the Eurasian population, easily allowing this to be one of the most deadly diseases in our history. It effected men, women, and children of all ages.
The impact was not limited to the population. In fact, because of the drastic effect on the population size this disease also had an impact on the economy. As people died from the plague bills were left unpaid and job positions were left unfilled.
