It should be a surprise to no one that France, being one of the largest and most populated countries in Europe, had been one of the largest sources of European immigration to the United States. French Americans are a massive demographic group, numbering in the multiple tens of millions, and the vast majority of French Americans descend from immigrants who came from France itself, rather than Quebec or Louisiana.
What if this was, somehow, not the case? What might cause French Americans to be, for example, only a tiny percentage of the U.S. population?
