A sourced introduction to Aia, its official settlement geography and the evidence used on this property-area page.
Aia is a village situated on the slopes of Mount Pagoeta in the Basque province of Gipuzkoa, Spain. It is located 30 km to the west of Donostia-San Sebastián and about 10 km inland from the coastal town of Zarautz. Aia is set amongst hills and forests, and surrounded by mountains. The town has a large church, the Church of San Esteban, which includes a notable centrepiece.
Aia is an official municipality of Gipuzkoa province, identified by INE code 20016. The linked structured record provides a recorded municipal area of 55.27 square kilometres and a reference coordinate of 43.2365, -2.1487. The coordinate is a municipal reference point, not a property, parcel boundary or radius from which local claims are inferred.
For Aia, the IGN Nomenclátor currently lists 3 official population nuclei. The imported source records are dated through 2025-12-03. The entry explicitly marked as the municipal capital is Aia, at a recorded elevation of approximately 312 metres. Other population-bearing nuclei in the extract include Andatza (145 residents in the cited settlement record). Nomenclátor entries describe settlement geography; they are not listing totals, neighbourhood boundaries or evidence of homes currently available for sale.
The market analysis for Aia is joined through the same INE code rather than a loose place-name match. This prevents similarly named places in other provinces from being blended together. Where a municipality-level series is unavailable, the page labels the province fallback explicitly; current NLS asking inventory remains separate from completed-sale, demographic and cadastral evidence.

The INE population series shown for Aia municipality runs from 2015 to 2023, moving from 2,034 to 2,139 residents. The published series therefore changes by +5.2% over that span; this describes resident population, not housing demand by itself.

Latest available demographic evidence from INE for Aia municipality; each measure states its own latest period.
Physical stock comes from Catastro. Energy-certificate and tourism-register counts are official administrative records and should be read as registered coverage, not as estimates of every home.
A Catastro building extract is not available in the current imported coverage for this scope. No wider total is substituted or presented as local stock.
Gipuzkoa province and País Vasco measures provide context; they are not substitutes for a municipality or neighbourhood value.
Completed-sale snapshot. Consejo General del Notariado / Penotariado aggregate for the stated scope. Price measures use 19 price-informed sales from 20 total recorded transactions. It is a current snapshot fetched 2026-08-03 21:39:29, not a historical point.
Transaction activity. MITMA quarterly housing transmissions, shown as published counts with no scaling or extrapolation.
Registered-price context. Colegio de Registradores quarterly statistics for the labelled comparison scope. Aggregate values are never relabelled as municipality or neighbourhood values.
Population and income. INE series for Aia municipality through 2023. Aggregate percentages and averages are population-weighted where appropriate.
Physical stock. Dirección General del Catastro building records. Counts describe recorded stock, not homes currently for sale.
Administrative registers. Official energy-certificate and, where available, tourism-register entries are matched to official geography; coverage is not a model of unregistered stock.
Geographic scope. Official municipality pages use their INE code. Legacy area-taxonomy pages inherit only a municipality or province scope that resolves unambiguously; no market value is derived from a listing location.
Current listings. The NLS active public inventory, shown separately as asking inventory and never blended into completed-sale statistics.
