This pictorial chart sample shows the population growth by continent in 2010-2013.
"Population growth' refers to the growth in human populations. Global population growth is around 80 million annually, or 1.2% p.a. The global population has grown from 1 billion in 1800 to 7 billion in 2012. It is expected to keep growing to reach 11 billion by the end of the century. Most of the growth occurs in the nations with the most poverty, showing the direct link between high population growth and low standards of living. The nations with high standards of living generally have low or zero rates of population growth. Australia's population growth is around 400,000 annually, or 1.8% p.a., which is nearly double the global average. It is caused mainly by very high immigration of around 200,000 p.a., the highest immigration rate in the world. Australia remains the only nation in the world with both high population growth and high standards of living." [Population growth. Wikipedia]
