Every 11 July, World Population Day invites us to reflect on where humanity is heading from a demographic perspective. The Day was established in the late 1980s in the wake of ‘Five Billion Day’ on 11 July 1987, the date on which the world’s population was estimated to have reached five billion people.
Today there are as many as 8.3 billion of us, but the annual growth rate – although it still represents an increase of around 70–75 million people a year – has fallen below 1 per cent per annum, and has been slowing steadily and significantly since peaking in the late 1960s, when the world’s population was doubling every 35 years.
Concerns about population explosion are overshadowed by those regarding inequality in reproductive behaviour, which has never been so extreme, with the lowest average of less than one child per woman in South Korea and the highest – still above six children – in sub-Saharan African countries.
It is therefore no surprise that the theme of this year’s World Population Day is ‘Realising the hopes and aspirations of young people – today and for the future’. Whilst the theme sounds encouraging, the figures suggest that it should also sound urgent.
In much of the world, a narrative has taken hold: the decline in fertility is said to simply reflect a shift in values. Young people are said to be turning their backs on family life, prioritising career, independence and freedom. It is a plausible story. But it is also, to a large extent, wrong.
