This communication seeks to analyze the degree of implementation of the 15-minute city model in Andalusia from new data sources based on geolocated Big Data such as Twitter or OpenStreetMap. For that, Twitter data collected in Andalusia over a period of 5 years is used with the aim of estimating points of residence. From these points, their areas of influence or isochrones are calculated using as a parameter a maximum walking time of 15 minutes. Next, points of shops and establishments downloaded from OpenStreetMap located within the 15-minute areas are added. These establishments are classified into eight categories according to the type of business, so that percentages are prepared to observe the degree of penetration of a certain type of business in a catchment area of 15 minutes walking from the point of residence. The analysis and cartography of the results show, on the one hand, that the concept of the 15-minute city in the large Andalusian capitals is mainly fulfilled in neighborhoods with a medium-high income level, while due to different circumstances it occurs to a lesser degree. in neighborhoods with a higher and lower income level, and in historical centers affected by gentrification processes. Regarding the medium cities, a correlation is observed in which the cities with a greater number of inhabitants have a greater number of shops located 15 minutes from the residences, while the less inhabited towns also have a lower number at their disposal. number of services. Finally, it should be noted that the isochrones located on the Andalusian coast do not usually comply with the concept of the 15-minute city, in contrast to the cities located in the Guadalquivir Valley.
