Only 5 of 26 Portuguese Sub-Regions Clear the National Development Average — INE's ISDR 2024 (Índice Sintético de Desenvolvimento Regional) Crowns Grande Lisboa Ahead of Porto Metro, Coimbra, Aveiro and Alto Minho

Lisbon — The Instituto Nacional de Estatística (INE — Statistics Portugal) released its 2024 Índice Sintético de Desenvolvimento Regional (ISDR — Synthetic Regional Development Index) on 15 June, and the headline reading lifts only five of Portugal's 26 NUTS III sub-regions above the 100-point national average. Grande Lisboa (107.83), the Área Metropolitana do Porto (AMP — Porto Metropolitan Area, 103.10), the Região de Coimbra (101.09), the Região de Aveiro (100.97) and Alto Minho (100.49) are the five that clear the line. The other 21 sub-regions print below the national mean, and the Autonomous Region of the Açores anchors the global tail at 92.95.

The ISDR is INE's flagship territorial-cohesion gauge, built annually from 65 statistical indicators — economic, demographic, social, educational, environmental and territorial — normalised against the national mean of 100 and aggregated into three dimensions: competitividade (competitiveness), coesão (cohesion) and qualidade ambiental (environmental quality). The 2024 base-year reading is the dataset that local councils, the Comissões de Coordenação e Desenvolvimento Regional (CCDRs — Regional Coordination Commissions) and the Agência para o Desenvolvimento e Coesão will use over the next twelve months when negotiating Portugal 2030 envelopes.

Competitiveness: Grande Lisboa runs a 16-point lead

The competitiveness dimension is where the regional concentration is most stark. Grande Lisboa prints 116.69 on the dimension — 16.69 points above the national mean — clear of every other NUTS III sub-region by a wide margin. The next tier sits around seven points above average: the Região de Aveiro and the Área Metropolitana do Porto both print in the 107 range. The Península de Setúbal, Cávado and the Autonomous Region of Madeira land 2.6 to 4.4 points below the line, with Madeira at 95.62 (up from 95.52 in 2023). Alentejo Central, at 90.11, is the best of the four Alentejo sub-regions but still nine points off the average. The two Autonomous Regions and the interior corridors carry the long tail.

Cohesion: nine sub-regions above 100, geography spreads wider

The cohesion dimension — built from indicators on income distribution, healthcare access, education completion and demographic balance — is the only one of the three with a broader top tier. Nine NUTS III sub-regions clear 100 on cohesion: Grande Lisboa (108.80) again leads, followed by the Região de Coimbra, Cávado, the AMP, Alentejo Central, Médio Tejo, Leiria, Alto Minho and the Região de Aveiro. The Autonomous Region of Madeira sits at 93.79, the largest year-on-year improvement among the islands (up from 92.85 in 2023).

Environmental quality: Açores top, Grande Lisboa pays for density

The environmental quality reading inverts the global ranking. The Autonomous Region of the Açores prints 113.84 on the dimension — the best of all NUTS III sub-regions — driven by indicators on air quality, protected-territory share, waste treatment and bathing-water classification. Madeira places second on the dimension at 106.31, down marginally from 106.67 in 2023 — the only one of Madeira's four dimensions to regress.

At the other end, the Região de Aveiro and the Alentejo Litoral — both heavy on industrial corridors and petrochemical capacity — print more than five points below the national environmental mean. The Algarve lands at 96.63, 3.37 points below the line, even before this year's wildfire season opens. Grande Lisboa, despite topping the global, competitiveness and cohesion rankings, sits in what ECO described as a posição bastante negativa (clearly negative position) on environmental quality — the density penalty that has held the metro back for the entire 12-year ISDR series.

NUTS II read: only Lisboa above 100, Madeira improves on three of four

At the NUTS II level (the seven regional aggregates Portugal reports to Eurostat), only the Região de Lisboa carries a global ISDR above 100. The Autonomous Region of the Açores prints 92.95 — the lowest of the seven — but its environmental-quality lead means it overshoots Madeira on the single-dimension read. Madeira itself moved up on three of four dimensions versus 2023: global 98.38 (from 98.16), competitiveness 95.62 (from 95.52), cohesion 93.79 (from 92.85), with only environmental quality regressing to 106.31 from 106.67. The Algarve fell short of the national average on every dimension reported.

What the index tells incoming residents

For incoming residents weighing where to settle, the ISDR is the closest thing INE produces to a like-for-like cross-region scorecard. The 2024 reading tells you where the labour-market depth, public-service density and demographic momentum are concentrated — Grande Lisboa and the AMP on competitiveness, the Coimbra-Aveiro-Alto Minho axis on the more balanced cohesion picture, and the Açores and Madeira if the immediate priority is air, water and protected-area share rather than wages. The 21 sub-regions below 100 are not failing — the index normalises to the national mean, so a sub-region below average still sits inside a country with a Banco de Portugal-revised 2.3% GDP-growth forecast for 2026 — but the spread between Grande Lisboa at 107.83 and the lowest interior readings is the same territorial-cohesion gap that the Plano Nacional de Coesão Territorial and the Plano de Recuperação e Resiliência (PRR — Recovery and Resilience Plan) were designed to narrow.

The 2024 release is the twelfth iteration of the ISDR. INE will refresh the underlying NUTS III boundaries when Eurostat's next regional classification revision lands; until then, the 26-sub-region geography stays. The next reading — covering reference year 2025 — is scheduled for June 2027.
