In what year Europe's population be the lowest?

Answer 1

This is impossible to answer, as the population cannot be projected for a long time towards the future and the population cannot be calculated for a long time in the past. Europe's population was obviously the lowest at 0 before mankind even existed. In the future, it is truly impossible to predict population far into the future without using the statistics of today. For example, Europe's population is expected to decline as the Birth Rate is dropping and there are large waves of emigration in Eastern Europe. However, Europe could have a comeback in a couple of years or could be far, far worse. What's to say that in five years, the birth rate of Europe won't be ten times the size of what it is today? Or what's to say a nuclear war won't break out in the next decade, wiping over half of the population of Europe off the map (and probably the world)? See, there are just so many possible outcomes and predications that it is impossible to tell the future population.

Today, Europe's population is about 750,000,000 and is the third most populous continent. It's population growth rate is at about -0.5%, the lowest of any continent. However, the fourth most populous continent, North America, has a population of about 550,000,000 and a population growth rate of about 1%. So it looks like Europe won't be surpassed anytime soon, as far as current predictions stand.
