What is the world's population when did it begins to explode?

As of October 2023, the world's population is approximately 8 billion. The population began to "explode" around the late 18th century, coinciding with the Industrial Revolution, which brought about significant advancements in agriculture, medicine, and sanitation. These developments drastically reduced mortality rates and increased life expectancy, contributing to rapid population growth. Since then, the population has continued to rise sharply, particularly in the 20th century.
