Economic history of Europe
Before 1800, France was the most populated country in Europe, with a population of 17 million in 1400, 20 million in the 17th century, and 28 million in 1789. The 17th and 18th centuries saw a steady increase in urban populations, although France remained a profoundly rural country, with less than 10% of the population located in urban areas. Paris was the largest city in Europe, in 1754, with 650,000 people by the end of the 18th century.
