Birth dearth
Birth dearth is a neologism coined by Ben J. Wattenberg in his 1987 book of the same name, which refers to the declining fertility rates observed in many modern industrialized, affluent societies. It is often cited as a response to overpopulation. Countries and geographic regions that are currently experiencing the highest rates of declining populations include Western Europe, Japan, the Russian Federation, and South Korea. Populations in other industrialized countries, such as the United Kingdom and the United States, and developing, poorer regions of the world, including the Balkans, Central Asia, the Middle East, and Sub-Saharan Africa, are also being impacted.
