Although it is illegal for the French state to collect data on ethnicity and ancestry, a law with its origins in the 1789 revolution and reaffirmed in the constitution of 1958, some surveys, like the TeO ("Trajectories and origins") survey conducted jointly by INED and INSEE in 2008, are allowed to do it.[209][210] Before this survey, it was estimated that 5 million people are of Italian ancestry (the most numerous immigrant community),[211] between three million[212] and six million[213] people are of North African ancestry, 2.5 million people are of Sub-Saharan African ancestry, 200,000 people are of Turkish ancestry,[214] and many more are of other European ethnic ancestry such as Spaniards, Portuguese, Poles, and Greeks.[211][215][216]
