The Dutch official census only collects data on country of birth, rather than ethnically; consequently, the total number of ethnic Turkish migrants (regardless of country of birth) nor the third, fourth or fifth generation of the Turkish-Dutch community have been collectively counted. Assistant Professor Suzanne Aalberse, Professor Ad Backus and Professor Pieter Muysken have said that "over the years" the Dutch-Turkish community "must have numbered half a million". However, there are significantly higher estimates. As early as 2003, the political scientist and international relations expert Dr Nathalie Tocci said that there was already "two million Turks in Holland". Rita van Veen also reported in "Trouw" that there was 2 million Turks in the Netherlands in 2007. More recently, in 2020, a report published in "L1mburg Centraal" estimated that there are more than 2 million Dutch-Turks. "Voetbal International" also reported in 2020 that the Dutch football club Fortuna Sittard will be carrying out annual scouting activities to find "Turkish talent" among the approximately 2 million Turkish-Dutch community.
