7.1 Population Skyrocketed

Europe's Population Boom

Between 1800 and 1900, Europe's population roughly doubled, growing from about 187 million to 400+ million. This surge resulted from declining death rates due to improved agriculture, sanitation, and medicine, while birth rates remained relatively high. The Agricultural Revolution ensured a more stable, abundant food supply, reducing famine deaths.

Causes of Decline in Mortality

Better nutrition, cleaner water, and advances like vaccination (smallpox) lowered death rates, especially infant mortality. Improved farming techniques (crop rotation, new tools) and the decline of epidemic disease (like plague) meant more people survived to reproduce, fueling continuous population growth throughout the century.

Consequences of Growth

Rapid population growth strained urban areas, worsening overcrowding and poor living conditions, but also supplied labor for industrialization. It spurred emigration to the Americas and colonies, and intensified social problems, prompting new political ideologies and social reform movements addressing poverty, housing, and public health.

Key terms

19th-century population growth

Europe's population roughly doubled from ~187 million (1800) to over 400 million (1900).

Main cause of population boom

Declining death rates from improved sanitation, medicine, and food supply, while birth rates stayed high.

Agricultural Revolution's role

New farming techniques increased food supply and reduced famine, supporting population growth.

Effect on cities

Rapid growth led to overcrowding and strained urban infrastructure, worsening living conditions.

Emigration link

Population pressure and limited opportunities pushed many Europeans to emigrate to the Americas and colonies.
