# Balearic Islands population and resource pressure > Live situation record from CLSTR: https://clstr.news/situations/balearic-islands-population-and-resource-pressure > Updated: 2026-09-02T09:18:00.000Z. Sources: 5. Developments: 3. The Balearic Islands are experiencing a significant discrepancy between official census data and the actual number of people present on the islands. In 2025, the effective average population reached 1.59 million, compared to 1.26 million official residents. By June 2026, the Human Pressure Indicator (IPH) reached a peak of over 1.93 million people, an increase of approximately 28,000 compared to June 2025. During that month, the archipelago maintained an average of around 1.89 million inhabitants. Regional data shows varying levels of pressure: Mallorca averaged over 1.39 million people, Menorca saw a 2.6% increase to approximately 180,000, Ibiza averaged 285,000, and Formentera experienced a 6.6% increase to nearly 29,000. Experts indicate that the primary challenge for the regional tourism model is the ‘temporal concentration of people’ rather than total annual visitor numbers. These seasonal peaks place immense strain on healthcare, public transport, water networks, and waste management. Additional pressures include the occupation of public spaces and the conversion of residential properties into vacation rentals. To mitigate these effects, recommendations include using real-time human presence data to fund services and regulating the real estate market to protect long-term housing for local residents. ## Claims - The official resident population of the Balearic Islands is 1.26 million.
