"Our calculations suggest that if the retirement age is raised to 65 by 2035, the pension budget shortfall could be reduced by 20% and received net pension can be increased by 30%, suggesting relief of both government and household burden," according to the report.

Fertility rates have halved across OECD countries — some of the world's richest nations — falling from about 3.3 children per woman in 1960 to about 1.5 children per woman in 2022, according to the OECD, or Organisation for Economic Co-operation and Development.

"This is significantly below the 'replacement level' of 2.1 children per woman needed to keep population constant in the
