SDG Indicator 11.7.1: Urban Public Space, Availability and Access, 2023 Release

The SDG Indicator 11.7.1: Urban Public Space, Availability and Access, 2023 Release, part of the SDGI collection, measures the average share of the built-up area of a city that is open space for public use for all. UN SDG 11 is "make cities and human settlements inclusive, safe, resilient and sustainable". Aside from environmental benefits, public space can also help improve public health, bolster community, and encourage economic exchange. As one measure of progress towards SDG 11, the UN has established SDG indicator 11.7.1. The indicator was computed by measuring both the proportion of OpenStreetMap (OSM) public space within a given urban center and the proportion of WorldPop gridded population within 400 meters to Open Public Space (OPS). Cities were delineated using the European Commission Joint Research Centre (JRC) Urban Center Database (GHS-UCDB). The SDG indicator 11.7.1 data set provides estimates of the average share of the built-up area of cities that is open space for public use for all for 8,873 urban centers across 180 countries.
To provide urban center level estimates of the average share of the built-up area of cities that is open space for public use for all.

SDG指标11.7.1：城市公共空间·供给与可达性（2023年发布版）隶属于SDGI数据集合集，该指标用于衡量城市建成区中面向全体公众开放的公共空间平均占比。联合国可持续发展目标11（SDG 11）的目标为“建设包容、安全、有韧性且可持续的城市和人类住区”。公共空间除具备环境效益外，还可助力改善公共健康、强化社区联结并促进经济往来。作为衡量SDG 11实现进展的指标之一，联合国设立了SDG指标11.7.1。该指标通过两类测算得出：一是给定城市中心内开放街图（OpenStreetMap, OSM）公共空间的占比，二是距离开放公共空间（Open Public Space, OPS）400米范围内的世界人口（WorldPop）栅格人口占比。城市边界的划定采用欧盟委员会联合研究中心（European Commission Joint Research Centre, JRC）发布的城市中心数据库（GHS-UCDB）。SDG指标11.7.1数据集为全球180个国家的8873个城市中心提供了“城市建成区中面向全体公众开放的公共空间平均占比”的估算值。
本数据集旨在提供各城市中心层面的“城市建成区中面向全体公众开放的公共空间平均占比”估算值。
