Spain shut Europe out and its colonial demography paid the price

Spain closed America to Europe, and demography paid the price

Spanish America received fewer Europeans than the Thirteen Colonies despite covering a vastly larger territory. The Hispanic Monarchy kept an iron grip on who could cross the Atlantic: nearly all of the flow came out of Castile, and other Europeans could only enter with special permits or irregularly. The result was a chronic "demographic anemia" in the viceroyalties, made worse by an indigenous population density ten times higher than north of the Rio Grande.

The contrast with British North America is stubborn. Up to independence, the Thirteen Colonies received around 500,000 Europeans; by the late eighteenth century the cumulative total exceeded 700,000. All of Spanish America, over the same period, received fewer, and nearly all of them came from Spain.

Why did Spain restrict immigration to America?

The Crown did not want subjects, it wanted loyal ones and tithes. It favored natives of its territories, especially Castile, and threw obstacles in the way of other Europeans: permits, naturalization, or ties to the Crown. The aim of this control was to preserve the political and religious loyalty of the territories. The Catholic angle does not save the counterfactual: an Irish Catholic despised London but would not swear allegiance to Madrid, and a French Catholic was a subject of the Most Christian King. Faith was not the brake; the pass of obedience was.

The spy excuse was not church-basement paranoia either. Dutch in the Caribbean, English in Jamaica from 1655, French on the Mississippi: every foreign settler was a potential bridgehead. France and Portugal were just as strict or stricter, and being an ally was worth nothing when dynastic wars renegotiated loyalty with every treaty.

The problem was not the funnel, it was the structure

Where there are dense indigenous populations and silver mines, you get encomiendas and haciendas. Where there is forest, few natives, and free land, you get farmers. Indigenous density is not a detail: it is the heart of the matter. There you do not bring in farmers, you bring in overseers. With massive Catholic immigration, the encomienda system would have given way to more family-sized estates, to a fabric of small merchants and artisans, and the push toward slavery would have been reduced.

Brazil is proof that the brake was money, not faith. Portugal was just as tight with foreigners, but the gold of Minas Gerais pulled the flow better than any royal decree: 600,000 Portuguese in a century, with a settlement rate above 85%. That said, with fewer than 10% women, many of them Azoreans brought over in family units. Mine colonization, not homestead colonization.

Canada: few settlers, rabbit-like birth rates

Quebec is the laboratory experiment. Only 8,500 settlers from metropolitan France between 1608 and 1760, with an estimated 20% women. They were enough to go from 65,000 French Canadians in 1763 to 1,300,000 in 1900. The filles du roi, some 800 women with a dowry from the king, did more for France than an entire fleet. The French were not scarce for lack of a door: France was not pushing them out.

There lies the key that separates two things often confused. Volume is decided by the push from the origin: misery, mines, hunger. Natural growth is decided by the settled family. And Spain, with the door closed, was left without the first.

The map that could have been and never was

Some projections speak of an Argentina of 70 million, a Uruguay of 10, and a Chile of 30. In the north of New Spain, California and Texas could have formed their own country along with northern Mexico, something like the Provincias Internas. Would the United States as we know it have existed? The numbers, simply, invite the question.

History is not written with conditionals. But the demographic contrast between the two Americas is still there, stubborn, waiting for someone to explain it without resorting to decree.
