The declining fertility rates and aging population in Japan and other developed countries are causing economic and social challenges. With fewer births and an aging workforce, there is a strain on social security and other forms of support. The economy may face contraction as consumption decreases and investment becomes restricted during deflationary times. The need for innovation and expansion becomes crucial, but it difficult to achieve in a shrinking population. Exporting to other countries to offset the loss of consumption is also challenging as many countries are facing similar demographic issues. Urgent and radical measures may be needed to avert the crisis and ensure sustainable economic growth.
