A gap means no data, not a zero value.
- Snowfall days (Climate and risks): The source has no value for this place.
- Strongest earthquake in the period (Climate and risks): The source has no value for this place.
City population is taken within administrative boundaries; “urban centre” figures describe the dense built-up cluster in GHSL; climate comes from the nearest weather station. These are not metro areas and are not comparable with US cities. There are no city-level quality-of-life indicators yet. Country: Spain.
