“ With a low birth rate for the past four decades, the absolute number of adults aged 20 – 24 has been falling rapidly. From 1995 to 2010 the number of people in this age cohort fell 32 per cent, and based on the number of people aged 0-4 years old in 2010, it is due to fall a further 20 per cent by 2030.”
