In 2014 Professor Pierre Vermeren reported in "L'Express" that the Turkish population was around 800,000. However, an earlier academic publication in 2010 by Dr Jean-Gustave Hentz and Dr Michel Hasselmann said that there was already 1 million Turks living in France. Professor İzzet Er, as well as the French-Armenian politician Garo Yalic (who is an advisor to Valerie Boyer), also said that there was 1,000,000 Turks in France in 2011 and 2012 respectively. More recently, the Turkish-French population has been estimated to be more than one million according to French-published articles in "Le Petit Journal" (2019) and "Marianne" (2020).
