In the 18th century, Europe shifted from periodic famines and high death rates to steady population growth. Higher agricultural productivity, better transportation, the disappearance of plague as a major epidemic, and smallpox inoculation increased the food supply and lowered mortality, while the European marriage pattern kept growth in check.
Why This Matters for the AP European History Exam
This topic builds your ability to explain causation and continuity and change over time, two reasoning skills the AP European History exam rewards. You should be able to explain what caused 18th-century population growth and trace its consequences for cities, families, and social order. These demographic shifts also set up later units, so understanding them helps you connect the Agricultural Revolution to later industrialization. Expect to use this content as evidence in arguments about social and economic change, whether in multiple-choice questions tied to documents or in extended written responses.
Key Takeaways
- By the mid-18th century, higher agricultural productivity and improved transportation increased the food supply, allowing steady population growth and fewer demographic crises. This process is called the Agricultural Revolution.
- Death rates fell because plague disappeared as a major epidemic disease and inoculation reduced smallpox mortality.
- Population growth was limited by the European marriage pattern (later marriage and more people never marrying) and, in some areas, by birth control methods, even as illegitimate births rose.
- As infant and child mortality dropped and commercial wealth grew, families spent more space and resources on children, child-rearing, and private comfort.
- The Agricultural Revolution produced more food using fewer workers, so people migrated from rural areas to cities for work.
- Urban growth strained city governments, eroded traditional communal values, and made poverty, crime, and prostitution more visible as social problems.
What Changed: From Famine Cycles to Steady Growth
In the 17th century, small landholdings, low-productivity farming, poor transportation, and bad weather limited and disrupted the food supply, causing periodic famines. Population could not grow steadily because food shortages and disease kept death rates high.
By the 18th century, the balance between population and food supply stabilized. This led to steady population growth and fewer of the demographic crises that had defined earlier centuries.
The Agricultural Revolution
By the middle of the 18th century, higher agricultural productivity and improved transportation increased the food supply. More reliable food meant populations could grow and demographic crises became less frequent. This shift is known as the Agricultural Revolution.
The key point for the exam is the chain of cause and effect: better farming and transport produced more food, more food supported more people, and more food produced with fewer workers freed labor for other work.
You may see specific innovations used as examples in textbooks and documents, such as new crop rotation methods, selective breeding, and consolidating farmland. Treat these as supporting examples of higher productivity, not as a required checklist.
Falling Death Rates
Two developments lowered mortality in the 18th century:
- Plague disappeared as a major epidemic disease.
- Inoculation reduced smallpox mortality.
Lady Mary Wortley Montagu is a useful example here. She helped popularize inoculation techniques against smallpox, which fits the larger pattern of improved disease control. Use her as an illustrative example, not as required content on its own.
Population Growth and Its Limits
Population grew, but it did not explode without limits. Two factors held growth in check:
- The European marriage pattern, which involved relatively late marriage and a notable share of people who never married, reduced the number of childbearing years for many couples.
- In some areas, various birth control methods also limited births.
At the same time, the rate of illegitimate births increased during the 18th century. So the picture is growth that was real but restrained, not unchecked.
Family Life and Childhood
As infant and child mortality decreased and commercial wealth increased, families changed how they used their resources. They dedicated more space and resources to children and child-rearing, and to private life and comfort.
This is where Enlightenment ideas about childhood show up. Jean-Jacques Rousseau's writing on education, new emphasis on schooling in places like Napoleonic France and Austria, and the rise of childhood themes in painting and portraiture all illustrate this shift. These are examples of the trend, not required facts you must memorize.
Migration to Cities
The Agricultural Revolution produced more food using fewer workers. With less rural labor needed, people migrated from the countryside to cities in search of work. Cities offered economic opportunities that pulled in this new population.
This migration transformed urban life and created real challenges:
- The growth of cities eroded traditional communal values.
- City governments strained to provide protection and a healthy environment.
- The concentration of the poor in cities made poverty, crime, and prostitution more visible as social problems, which prompted increased efforts to police marginal groups.
How to Use This on the AP European History Exam
Causation
Be ready to explain why 18th-century population grew. Strong answers connect higher agricultural productivity and improved transportation to a larger, more reliable food supply, then link that food supply to steady population growth and rural-to-urban migration. Adding falling death rates from the end of major plague epidemics and smallpox inoculation strengthens the explanation.
Continuity and Change
Contrast the 17th century (periodic famines, high mortality, limited growth) with the 18th century (stabilized food supply, steady growth, urbanization). Note that growth was still limited by the European marriage pattern, so you show change without overstating it.
Using Sources Effectively
When you read a document about poverty, crime, city life, or child-rearing, connect it to these larger trends. A source describing urban poverty or efforts to police the poor fits the pattern of cities straining under rapid migration. A source emphasizing children and private comfort fits the shift in family life tied to falling child mortality and commercial wealth.
Common Trap
Do not turn this topic into the Industrial Revolution. The Agricultural Revolution and population growth set the stage for industrialization, but factories, steam power, and the factory system belong to later units. Keep your evidence here focused on agriculture, demographics, and early urbanization.
Common Misconceptions
- The Agricultural Revolution is not the Industrial Revolution. Machines like the steam engine and the factory system come later. For this topic, focus on farming productivity, food supply, population, and migration.
- Population growth was not unlimited. The European marriage pattern and, in some areas, birth control methods kept growth steady rather than explosive, even as illegitimate births rose.
- Lower mortality was not caused by modern medicine. Plague fading as a major epidemic and smallpox inoculation mattered most here, not advanced hospitals or germ theory, which came later.
- Cities did not simply offer a better life. They drew migrants with economic opportunity but also strained governments and made poverty, crime, and prostitution more visible as social problems.
- More attention to children was tied to specific causes. Falling infant and child mortality plus growing commercial wealth let families invest more in children and private comfort, rather than a vague change in attitudes alone.

Frequently Asked Questions
What caused 18th-century population growth in Europe?
Population grew because agricultural productivity and transportation improved, food supplies became more stable, plague faded as a major epidemic, and inoculation reduced smallpox mortality.
What was the Agricultural Revolution in AP Euro?
The Agricultural Revolution was the rise in agricultural productivity that increased food supply and reduced demographic crises. It helped support population growth and freed rural workers to migrate to cities.
How did disease patterns change in the 18th century?
Plague disappeared as a major epidemic disease, and smallpox inoculation reduced mortality. These changes helped lower death rates and support steady population growth.
What was the European marriage pattern?
The European marriage pattern involved relatively late marriage and a significant share of people never marrying. It limited population growth by reducing the number of childbearing years for many people.
How did 18th-century urbanization affect European society?
Cities attracted rural migrants seeking work, but rapid growth strained city governments, weakened traditional communal ties, and made poverty, crime, and prostitution more visible as social problems.
