Counted in OpenStreetMap within 800 m of the town centre, taken as the point OpenStreetMap marks as the town's centre, moved at most 500 m to the busiest nearby spot (for a few spread-out municipalities without such a point: the busiest spot near the official coordinate). OpenStreetMap is kept by volunteers: very complete in most Spanish towns, thinner in some. “Everyday essentials” only asks whether the basics are there, so a small town can score 6 of 6; “lively centre” ranks each count among all 333 places and averages them, so it mostly reflects size. Large municipalities with several centres (Lorca, Oleiros, Ames…) can score low because their official centre is a small village.
Holiday lets and beaches

Tourist apartments: INE count of homes listed on Airbnb, Booking and Vrbo. A high share means busy summers and pressure on rents.

Water
- River basin
- Cuencas Internas De Cataluña
- Reservoirs now
- 73.6% full (week of 2026-09-29); the same week in the previous 10 years averaged 57.5%
- Worst week 2016-2025
- 14.5% full (2024-03-05)
- Weeks below 40% full, 2016-2025
- 26% of all weeks
Ministry for the Ecological Transition, weekly hydrological bulletin: all reservoirs over 5 hm³ in the basin. Low reservoirs are what led to drought restrictions in Catalonia (2023-24) and Andalusia (2022-24). Some basins (Segura) also rely on transfers and desalination, so their reservoir level alone overstates the risk of taps running dry.
