Fertility rates continue to fall across the Asia Pacific Region (APAC), placing pressure on the economy, healthcare systems, and society as a whole. It is not just a question of population size; increasing old-age dependency ratios beg the question of how a diminishing workforce will be able to pay for the services necessary to serve an ageing population. In many countries, it is the women who are expected to shoulder the burden of homecare and childcare duties, even if they are working full time themselves. What can policymakers in APAC countries do in order to help couples achieve the family size they desire and perhaps turn the falling fertility rate around, or at least slow the rate of population decline? And importantly, where should investment be placed to make the biggest impact? Economist Impact has authored a series of papers, sponsored by Merck, on the issue of low fertility rates in APAC countries. We explored the evidence base and cost-effectiveness for interventions such as workplace policies, parental leave, childcare provision, financial incentives and assisted reproductive technology, and discussed wider cultural and economic issues that may be impeding action. This presentation will describe the main findings from our previous work, including a recent policy prioritisation “Toolkit” that was designed to be used by policymakers in the region to help inspire the development of policy ideas to address falling fertility rates, and support discussions on where funding should best be targeted. We shall also describe our current research project on the development of a policy “Scorecard”, which compares and contrasts the fertility and family-friendly landscape in countries across APAC, to explore what policies are being implemented in practice in the region, and provide local suggestions for improvement and where funding should be allocated.
