Previous green space equity studies have relied on access measures, such as the distance to, number of, or size of green spaces and have produced mixed results on green space disparities in the U.S. While the benefits of green spaces can be fulfilled when people visit them, attention to the differential use of green spaces has been less common. We examined green space inequalities using traditional access measures in order to understand which group has lower access to local parks and then investigated which urban residents visit local parks more using SafeGraph’s mobility data. We found that the Phoenix metro area experiences green space access disparities by age group and (partially) income rather than by race and ethnicity. Access to local parks consistently decreased as the percentage of the elderly population increased in a neighborhood. However, the visit to local parks consistently increased as the percentage of children and the elderly increased. We discuss the implications of our findings for urban planning.

以前的绿色空间公平研究依赖于获取措施，例如到绿色空间的距离、数量或大小，并且对美国的绿色空间差异产生了不同的结果虽然人们访问绿色空间时可以实现其好处, 对绿色空间的差异化使用的关注已经不那么普遍了。我们使用传统的访问措施检查绿地不平等，以了解哪个群体访问当地公园的机会较少，然后使用 SafeGraph 的流动性数据调查哪些城市居民更多地访问当地公园。我们发现，凤凰城都会区经历了按年龄组和（部分）收入而非种族和民族划分的绿地访问差异。随着社区中老年人口比例的增加，进入当地公园的机会持续减少。然而，随着儿童和老人比例的增加，对当地公园的访问量持续增加。我们讨论了我们的发现对城市规划的影响。
