Answer:
Population growth after World War II exploded all over the world, both in industrialized nations where a phenomenon known as baby boom took place, and in the developing world as well.
Explanation:
Population growth in the world was particularly high in the 1950s, 1960s, 1970s, and early 1980s, and from then on, it began to taper off. The world population actually doubled between 1950, with only 2.5 billion, and 1987 with 5 billion.
In the developing world, population growth continued to be high throughout the twentieth century, due to higher birth rates. This is especially true of Africa, the continent where population grew the most after World War II.
In industrialized nations though, the baby boom ended in the late 1960s, and ever since, population growth has been falling steadily, to the point that several of these countries have negative natural growth rates and if not for immigration, their populations would be declining (countries such as Germany, Italy and Spain are an example).
