Database for the classification of medium and small cities

This database compiles information on socio-economic and demographic variables of medium-sized and small cities in Spain. It includes indicators related to population, employment, motorization rate, accidents, meteorology, and pollution, among others. The database has been used in a study to classify Spanish cities based on their socio-economic and demographic characteristics, with the aim of assessing their suitability for the implementation of Low Emission Zones (LEZ).本数据库收录了西班牙中小城市的社会经济与人口统计学变量相关信息，涵盖人口、就业、机动化率、事故、气象及污染等多类指标。 本数据库已被应用于一项基于社会经济与人口统计学特征对西班牙城市进行分类的研究，旨在评估其适配低排放区（Low Emission Zones, LEZ）的落地条件。
