How did it change and what will the age structure of populations look like in the future? It comes to an end when the average number of births per woman – the fertility rate – declines. Life expectancy, which measures the age of death, has doubled in every region in the world as we show here.Ĭhild & infant mortality – Mortality at a young age has a particularly big impact on demographic change.įertility rates – Rapid population growth has been a temporary phenomenon in many countries. Life expectancy – Improving health leads to falling mortality and is, therefore, the factor that increases the size of the population. ![]() We explain how we know that population growth is coming to an end, and present projections of the drivers of population growth. The world population growth rate declined from around 2% per year 50 years ago to under 1.0% per year.įuture population growth – This article focuses on the future of population growth. The world population increased from 1 billion in 1800 to around 8 billion today. When and why did the world population grow? And how does rapid population growth come to an end? These are the big questions that are central to this research article.
