Defining and measuring spatial inequalities across the urban environment remains a complex and elusive task that has been facilitated by the increasing availability of large geolocated databases. In this study, we rely on a mobile phone dataset and an entropy-based metric to measure the attractiveness of a location in the Rio de Janeiro Metropolitan Area (Brazil) as the diversity of visitors' location of residence. The results show that the attractiveness of a given location measured by entropy is an important descriptor of the socioeconomic status of the location, and can thus be used as a proxy for complex socioeconomic indicators.

熵作为衡量里约热内卢大都市区吸引力和社会经济复杂性的指标

定义和测量整个城市环境中的空间不平等仍然是一项复杂而难以捉摸的任务，而大型地理定位数据库的可用性不断提高，这促进了这一任务。在这项研究中，我们依靠手机数据集和基于熵的指标来衡量里约热内卢都会区（巴西）作为游客居住地点多样性的一个地点的吸引力。结果表明，由熵衡量的给定位置的吸引力是该位置社会经济地位的重要描述符，因此可以用作复杂社会经济指标的代理。
