INSEE, in its population forecasts for Réunion in 2050, It is supplemented by two other scenarios : 916 000, 1 million or 1,076 million d’habitants. The Institute favors a middle scenario, based on the assumptions of stable fertility, life expectancy which continues to increase and a slightly negative migration balance of 1,800 people per year. This reference scenario results in a result of 1,022 million inhabitants in the middle of the century. It is supplemented by two alternative scenarios. In the high hypothesis, based on a stronger increase in life expectancy and a greater arrival of populations from the Indian Ocean zone (which can be explained in particular by the consequences of climate change, specifies INSEE), the population would reach 1,076 million people in 2050. In the low hypothesis which simulates a drop in fertility, a lower progression in life expectancies and greater departures to France, the population would stabilize in 2047 at around 916,000 inhabitants.
