Whatâs going on here? Research published this week suggested that declining birth rates in many countries could reshape the global economy. What does this mean? The global population will tick up from todayâs 8 billion to 9.7 billion by 2050, according to the United Nations. Yet at the same time, medical journal The Lancet predicts that three-quarters of all countries will struggle to keep their populations stable from 2050. Thatâs because birth rate projections arenât equal across the board. Women are statistically expected to have 2.1 children each to build the next generation â a daunting expectation that many are now ignoring, especially in wealthier countries. That means most of the future population increase will come from lower-income areas, specifically in Asia and sub-Saharan Africa, where climate change and limited resources are already straining communities. Why should I care? Zooming out: Money makes the difference. Countries with shrinking populations will end up with shrinking workforces, too, which can be a serious drag on their economies. The opposite is true when a countryâs population increases: a bigger and younger workforce means more productivity and economic growth, as well as a wider pool of consumers for companies to sell to. That only works with the right infrastructure, though, so developing countries â where populations are expected to increase â need to attract enough money to fund education, businesses, and healthcare services to make sure their economies donât bust, but boom. The bigger picture: People schmeople. Japanâs workforce is already weakening, and with the countryâs birth rate falling for the eighth year in a row, that trend looks locked in. In fact, Japan is projected to have 11 million fewer workers by 2040, with nearly a third of its population landing in the over-65 category. Donât forget, though, that weâre hurtling toward a future run by robots: Japanâs already rolling out AI avatars and services to plug the gap â so maybe AI wonât steal jobs, but scavenge them. |
