The population density of Europe, as a whole, is 143 people per square mile. This makes Europe the second most densely populated continent in the world, with the first place being occupied bu Asia, so we can say that Europe is a densely populated continent as a whole.
It has to be taken in notice that Europe is a continent that has an aging population, the fertility rate is very low, and the life expectancy is high. Interestingly enough, even though there's only three countries in the whole continent that have a positive fertility rate, the population of the continent is still growing, slowly, by 0.3% annually, but it is growing. The growth is mainly because of the migrants, mainly from the Middle East and Africa, and apart from increasing the number of the population with their entry, they also tend to have a high fertility rate.
