1. Population growth

   • World population before the 19th
     • At first population grew slowly. Wars, epidemics and large-scale migration also either limited or promoted population growth. In the first century the population was about 256 million, it increased until the black death of 1342 decimated the European population
   • The European population
     • In the ancient history and the Middle Ages wars and epidemics slowed down the population growth and the black dead decimated more the population. In the early modern age the European population experienced a slight growth that was slowed down by the plagues and epidemics. In the modern age the industrial revolution caused a big increased in population growth, in the 19th and the 20th many Europeans emigrate to the americas, two world war caused a lot of dead at that moment. In the 21st century population growth in Europe has stagnated, although immigration has helped to offset low European birth rates.

     • At the beginning of this period, world population grew more rapidly because of higher birth rates and lower death rates. The industrial revolution made this increase. Between 1800 and 1900 world population doubled, in 1950 it reaches the 2500 million, between 1950 and 1990 the world population doubled again, by the year 2000 it was more than 6000 million, in 2015 world population exceeded 7300 million.

   • Demographic deserts
     • This are places with the lowest population density that have some negative factors such us: Adverseclimate conditions, Adverse vegetation, Mountainous relief Geographic situation and historical settlement and Areas used for extensive agriculture.
