France: Western Europe's Demographic Anomaly

France ran out of children before anyone else and still hasn't paid the price

In 1700, France had 22 million inhabitants compared to England's 7 million and Germany's 15 million. It was the "China of Europe," a label coined by Franklin from the Paris embassy with more wit than admiration. Two centuries later, that lead had vanished: in 1870, Prussia fielded 38 million souls against the rest of Germany's 65 million and won the war through sheer reserve arithmetic. The question isn't whether France stagnated, but why it did so before its neighbors and without any catastrophe.

Birth control reached the countryside before the Revolution

The timeline dismantles the easy explanation. Birth control was already present in Norman fields and the Garonne valley before 1789. While the rest of the continent entered the demographic transition around 1870, France had experienced a century of sustained decline. It wasn't a revolutionary accident: it was a bedroom decision ahead of its time.

The Napoleonic Code Civil added fuel to the fire with equal inheritance laws: each child received a smaller slice of land. Where primogeniture concentrated capital and labor, partition fragmented both. French agrarian structure ended up resembling Catalonia's hereu system more than Galicia's smallholdings with eight children per woman, and smallholders have fewer children because every extra mouth is a bill.

The Thirty Years' War explains nothing

The contrast with Germany is the most painful. German territories lost a third of their population in the 17th century yet multiplied in the 19th. Catastrophic mortality is absorbed in two generations, and fertility returns. France had no catastrophe: it had voluntary decline, and voluntary decline doesn't recover because there is nothing to recover.

England did the opposite: it expelled the surplus. Dissenters, convicts, and labor first, settlers later. The Thirteen Colonies grew from about four million in 1790 to surpass the British population by 1850. A demographic dumping ground with sea access is an escape valve; France, lacking one, kept the pressure inside.

Paris as a sink and macrocephaly as a burden

The capital went from just over 500,000 inhabitants in 1800 to 2,700,000 in 1900. Rural exodus wasn't unique to France — Barcelona and Madrid also grew — but Parisian concentration reached a different scale. The gap between Paris and Lyon, the second metropolitan area, is much larger than the one separating Tokyo from Keihanshin, which has 20 million inhabitants.

Some argue hypercentralism emptied the country and made housing expensive enough to be demographically inefficient. Counterarguments point to the UK being equally or more centralized yet continuing to grow. Macrocephaly explains the geography of population, not its volume.

Immigration without density: the anomaly continues

In 1901, France was the world's second-largest host of foreign-born residents after the US, at 3% of the total. This isn't a pogre merit: it's what happens when a country runs out of arms due to Malthusianism and must import them from Belgium, Italy, and Poland for mines and metallurgy. Lots of immigrants, yet the country remains sparsely populated. That is the anomaly.

Densities confirm this: 121 people per square kilometer versus Italy's 196, Germany's 236, or England's 438. And the counterfactual stings. If France had trinc the Prussian curve, it would today be the continent's leading power with more muscle than Germany. It didn't, and here we are debating whether it was the Code Civil, Paris, or the guillotine.
