What will happen with the market if the fertility rate is low?

If the fertility rate is low, the market may face a shrinking labor force and increased aging population, leading to potential labor shortages and higher healthcare costs. Consumer demand could also decline as fewer young people enter the market, impacting sectors like housing and education. Additionally, governments may need to adjust policies, such as increasing Immigration or incentivizing higher birth rates, to mitigate these effects and sustain economic growth.
