Food and nutrition
What is the Malthusian trap?
Industrial Revolution
Chronic hunger and malnutrition were the norm for the majority of the population of the world including Britain and France, until the latter part of the 19th century. Until about 1750, in large part due to malnutrition, life expectancy in France was about 35 years, and only slightly higher in Britain. The U.S. population of the time was adequately fed, were much taller and had life expectancy of 45–50 years. In Britain and the Netherlands food supply had been increasing and prices falling before the Industrial Revolution due to better agricultural practices; however, population was increasing as well, as noted by Thomas Malthus. Prior to the Industrial Revolution, advances in agriculture or technology soon led to an increase in population, which again strained food and other resources, limiting increases in per capita income. This condition is called the Malthusian trap, and it was finally overcome by industrialization. Transportation improvements, such as canals and improved roads, also lowered food costs. Railroads were introduced near the end of the Industrial Revolution.
