Jennifer D. Sciubba explains that while the total global population is still growing, the growth rate has been falling since the 1960s. Many countries are experiencing or will soon experience significant population decline due to low fertility rates, including China, South Korea, Japan, and Italy. Even India, while still populous, has below-replacement fertility.
The speaker highlights the fundamental shift towards pervasive low fertility and population aging, projecting that by mid-century, there will be more people over 60 than under 14. She presents three possible future worlds: a 'head-in-the-sand' world that clings to the status quo, a 'fearful' world characterized by coercion and division, and a 'resilient' world that adapts to an older, smaller population.
This scenario involves societies ignoring the problem, continuing with economic models that assume infinite growth, and attempting to incentivize more births (which has proven ineffective, as seen in South Korea). This path leads to struggling social safety nets, strained national budgets, and eventual system overload and breakdown.
In a fearful world, the ability to choose family size is diminished, immigration becomes restricted, and division and hatred increase. Global cooperation on critical issues like pandemics and climate change is hindered as countries become more insular. Historically, coercion to increase birth rates, such as in Ceaușescu's Romania, has led to dire consequences.
A resilient world proactively plans for an older, smaller population. It involves attracting global talent through immigration (like Canada), rethinking work for older ages, leveraging technology for productivity, and prioritizing investment in health rather than dictating population size. This world also focuses on sustainable consumption and provides support for countries undergoing demographic transitions.
The transition to an older population is happening much faster in developing countries. Sciubba emphasizes the need for these nations to proactively implement policies, such as moving away from informal economies, to protect their aging populations. She concludes by stating that population aging is an inevitable shift, and societies must choose to imagine and create a resilient future, embracing an older, smaller world as a beautiful one.
