A Frenchman writes to Mark Steyn to ask is some of France’s fertility might be explained by actual Frenchperson’s giving birth:

MARK REPLIES: Well, first things first. There are no “official” figures because France, as a matter of policy, does not keep records on Muslim vs non-Muslim births. SteynOnline–Letter Column

This is something that David Orland has written about on VDARE.com–see Connerly’s Racial Privacy Initiative: The Unhappy French Connection.

The problem here is that if you ban statistics by race, you not only prevent the government from using them for bad purposes, you prevent anyone from using them for anything. Ignorance is not necessarily bliss.

With no official data, you have to try using the evidence of your eyes–Steyn is quoted as saying

“What’s the Muslim population of Rotterdam? Forty percent. What’s the most popular baby boy’s name in Belgium? Mohammed. In Amsterdam? Mohammed. In Malmo, Sweden? Mohammed.”LP: Say Goodbye to Europe

And I’ll take this opportunity to repeat that the demographic arguments Steyn is making are the same ones that Linda Chavez and the SPLC criticized Dr. John Tanton for making in 1986.
