This lesson introduces demographic transition: the long-term shift from high birth and death rates to low birth and death rates as societies change. Understanding the idea helps explain population growth, economic development, and differences between countries.
Demographic transition describes a historical change in population patterns associated with development. In a society with high birth and death rates, population growth may be slow. As death rates fall while birth rates remain high, population grows rapidly. Later, birth rates also decline, and growth slows.
