This dataset supports the METRO·MIX research project, which investigates urban proximity and land-use mix as foundational criteria for promoting healthier, more compact metropolitan areas. The data are organized into three main components: General Data, City Data, and 15-Minute City Data, covering the Spanish cities of Barcelona, Madrid, Málaga, and A Coruña between 2021 and 2023.

The General Data includes harmonized national-scale information derived from cadastral records and demographic statistics provided by the Spanish Land Registry and the National Institute of Statistics (INE), with variables such as land use categories, building function, population structure, and socioeconomic indicators.

The City Data component provides spatially disaggregated information at the census section level for each city, integrating official records with field-collected data on urban functions. This data was processed to derive indices such as the Residential/Non-Residential Balance (RNR Index) and the Land Use Mix Index (LUM Index), facilitating comparative urban analysis.

The 15-Minute City Data focuses on neighborhood-scale accessibility and functional diversity, particularly in Barcelona. It incorporates high-resolution, geolocated data on ground-floor commercial activities, categorized and verified through in-situ fieldwork and a custom-built mobile application.

All datasets were processed using GIS software (QGIS 3.32) and validated through a multi-step quality control process, including spatial checks, field verification, and harmonization protocols. The dataset is structured in open formats (CSV, GeoJSON, Shapefiles) and intended to support further analysis in urban planning, geography, and public health research.
