Steady decline in the population

Just 39% of the capital's residents were locals in 1920. Against this background, approximately 50% of the city's population is made up of migrants from the French countryside, with the remaining 10% coming from abroad.

Another key aspect in France's history that affects this case is the country's population. France was the most populous country in Europe during the Middle Ages and Renaissance, with one in every 4-5 people in Europe estimated to be French. France was the fourth most populated country in the globe during the time of the Napoleonic Wars, after China, India, and Japan, which contributes to French dominance over the continent at the time. But when the XVIII century came to an end and the XIX century began, the country's population began to decrease. The birth rate is beginning to decline. around 2 million French people died as a result of the Revolution and the Napoleonic Wars. Throughout the nineteenth century, battles resulted in greater mortality rates than birth rates. In the 20th century and the First World War, France lost around 1,357,800 soldiers - killed and missing - not to mention civilians killed. Such a shock to the population affects not just the loss of these young men's lives, but also the loss of the children they may have had.
