1975 Population

In 1975, the world’s population was approximately 4 billion people, marking a period of rapid growth driven by post-World War II advances in health and agriculture. Asia was the most populous continent, home to over half the global population, with China (around 930 million) and India (about 620 million) as the two largest countries. Europe, while still significant, was experiencing slower growth, with a population of roughly 460 million. Africa’s population was around 420 million, reflecting high birth rates but also high mortality rates. North America had about 230 million people, with the United States accounting for most of that at nearly 215 million. Latin America and the Caribbean together had about 320 million inhabitants, with Brazil and Mexico as the largest countries in the region. Oceania, including Australia and the Pacific Islands, was the least populated region, with fewer than 20 million people. This demographic landscape set the stage for the continued global population boom in the decades that followed.
