France is projected to experience a significant increase in its immigrant population through 2070, driven by a continuing decline in the national birthrate. Net migration forecasts are 50% higher than those of the previous three decades, indicating a substantial influx of new residents. This projected migration represents millions of individuals expected to settle in France over the next four decades. The demographic shift is anticipated to counterbalance the country’s decreasing birthrate, impacting its future population structure. These projections are based on current trends and offer a long-term outlook on France’s evolving demographics. The data suggests immigration will play an increasingly vital role in maintaining France’s population size and potentially its economic stability.
