Countries transition through these demographic stages at different tempos. France was a pioneer in this regard, showing early signs of fertility decline influenced by changing attitudes and policies. However, by the late 20th century, a fertility crisis began to emerge in many developed nations, leading to birth rates falling below replacement levels.
In Asia, rapid fertility decline has occurred, particularly in countries like Korea and China, while Africa continues to show significant differences, with some developed regions nearing replacement levels while others remain high.
