From 2015 to 2019, 12,600 people left Reunion each year for the mainland and 10,800 people went the other way., reveals an INSEE study. The trend recorded during the period 2010-2014 has become more pronounced. Departures mainly occur between 18 and 24 years old (3,400 each year, for 1,300 arrivals) and are mainly motivated by the pursuit of studies. Among the active, departures are a little more numerous (6,600 per year) that the arrivals (6 300). Four out of ten migrations are linked to a transfer to the civil service. Arrivals from Mayotte are limited to 550 on average per year and as many people traveling in the opposite direction. Out of 1,500 people arriving on the island from abroad each year, four out of ten were born in France, 400 come from Madagascar and a few dozen from Mauritius and the Comoros. The study also shows that people from Reunion Island by birth are not very inclined to mobility.. Only 44% of people who left the island between 2015 and 2019 were born there and regardless of age, natives of Réunion are a minority among the arrivals.
