What declining birth rates mean for the world | BBC News

Summary

The world's population is growing while birth rates are declining, with South Korea and Japan experiencing record lows. This demographic shift leads to an aging population and potential economic challenges, such as increased healthcare and pension costs with fewer taxpayers. Solutions to boost birth rates, like cash incentives and improved childcare, have been attempted with limited success. Meanwhile, global population growth continues due to increased lifespan and high fertility in some regions, raising concerns about climate impacts.

• 🌐 Some countries like the UK will see population increases due to immigration, but this doesn't fully counter the impacts of low birth rates.
• 👵 Aging populations due to low birth rates and longer life expectancies lead to increased elderly proportions.
• 🏥 Governments face challenges with increased healthcare and pension costs due to fewer taxpayers.
• 💼 The Economist suggests implications of low birth rates include higher taxes, later retirements, and potential government budget crises.
