This Wednesday, November 24, INSEE communicated its demographic projections for 2070. Some departments of Occitanie will experience strong growth. Others will decline slightly.

With 824,000 additional inhabitants, Occitanie should be the region of France which will experience the strongest demographic growth by 2070.

However, INSEE projections show significant inequalities between the departments of the region. Some are expected to experience strong growth. Others will see their population decline.

## These departments which are going to gain inhabitants

Contents

Most of the increase should indeed be concentrated in two departments: Hérault (+ 27.6%) and Haute-Garonne (+ 27.3%).

The demographic growth of these two departments should mainly be played out in the coming years since the Hérault should gain 271,000 inhabitants by 2050, and the Haute-Garonne 327,000.

Between 2050 and 2070, growth slows down sharply with respectively 49,000 and 42,000 additional inhabitants in these two departments.

## Decreases in the least populated departments

Apart from these major leaps forward, demographic growth should be weaker elsewhere in the region. We note all the same an expected increase of 9% in the Tarn, 8% in the POs, 6% in the Aude and 2.3% in the Gard.

Conversely, other departments should lose inhabitants. This is the case of the Hautes-Pyrénées, which should lose more than 9,000 inhabitants, i.e. a drop of 4% in its population. For Aveyron, a drop of slightly more than 1% is expected.
