The global human population in the 19th century experienced significant growth, starting at approximately 1 billion around 1800 and reaching about 1.65 billion by 1900. This increase was largely driven by advancements in agriculture, medicine, and sanitation, which reduced mortality rates. The population growth varied by region, with Europe and North America seeing the most substantial increases. Overall, the 19th century laid the groundwork for the rapid population expansion of the 20th century.
