Tunisia is facing a significant new challenge as it enters a period of demographic decline. This trend emerges while the nation is already struggling with deep-seated economic and social instabilities. The country previously experienced one of the fastest demographic transitions in the Mediterranean region. Now, the shift toward a shrinking population threatens to impact Tunisia's long-term future. This demographic downturn could exacerbate existing systemic vulnerabilities. Addressing this decline will be critical for the country's future stability. The situation presents a complex hurdle for policymakers already managing a crisis.
