Ο συνολικός αριθμός των χριστιανών που τράπηκαν σε φυγή για την Ελλάδα ήταν περίπου 1,2 εκατομμύρια, με τον κύριο όγκο φυγής το 1922 πριν την υπογραφή της Σύμβασης. Σύμφωνα με επίσημα αρχεία της Μικτής Επιτροπής που συστάθηκε για να επιβλέψει τις ανταλλαγές, οι "Έλληνες" που μεταφέρθηκαν μετά το 1923 ήταν 189.916 και οι Μουσουλμάνοι που απελάθηκαν στην Τουρκία ήταν 355.635 [Ladas I932, 438-439; Αλλά χρησιμοποιώντας την ίδια πηγή ο Eddy 1931, 201 δηλώνει ότι η μετά το 1923 ανταλλαγές περιελάμβαναν 192.356 Έλληνες και 354.647 Μουσουλμάνους.]
"Yussuf Kemal Bey had remarked at the previous meeting (16 March 1922), where speaking of the fundamental principles of peace, that Lord Curzon had dwelt upon the safeguarding of minorities". He also noted that "the Ankara Government was strongly in favour of a solution that would satisfy world opinion and ensure tranquillity in its own country. It was ready to accept the idea of an exchange of populations between the Greeks in Asia Minor and the Muslims in Greece". In reply to this proposal, Lord Curzon noted that "no doubt something was possible in this direction but it was not a complete solution. The population in Asia Minor was somewhere near half a million. For physical reasons such a large number could not be entirely transported and for agricultural and commercial reasons many of them would be unwilling to go".
At the time of the Lausanne Conference, there were still about 200,000 Greeks remaining in Anatolia ; the Moslem population of Greece, not having been subjected to the turmoil of the Asia Minor campaign, was naturally almost intact. These were the people who, properly speaking, had to be exchanged.
