Answer 1

Between 1950 and 1990, the world's population experienced rapid growth, increasing from approximately 2.5 billion to about 5.3 billion people. This surge was driven by advancements in healthcare, agriculture, and sanitation, which significantly reduced mortality rates and improved life expectancy. Additionally, high birth rates in many developing countries contributed to this population boom. The period marked significant demographic shifts, with urbanization and migration patterns changing as people moved to cities for better opportunities.
