Around 1750, the demographic development is interrupted. In 1700 the world population was 600 million, was reached in 800 to 900 million in 1850-1870 to 1.2 billion. Since 1750 so the population soared to double after only a century. The causes of this demographic growth was the decrease in the mortality rate and longer average life and for that there is a demographic revolution as there was the final demise of the old regime.The decline in mortality was determined by advances in medicine and hygiene, and even the plague disappeared.
