Several countries are experiencing a fall in the number of babies being born and this has potentially serious consequences. Japan’s Prime Minister, Fumio Kishida, has warned that his country is on the brink of not being able to function as a society. The problem is an increasingly elderly population and not enough younger people to keep the country ticking over. China is seeing record low birth rates and South Korea has the lowest rate of women having babies in the world. Youtubers Sarah and Kyuho in the South Korean capital Seoul, describe some of the pressures and reactions they experienced when they said they are not planning to have kids.
