SDG Indicator 11.2.1: Urban Access to Public Transport, 2023 Release

The SDG Indicator 11.2.1: Urban Access to Public Transport, 2023 Release, part of the SDGI collection, measures the proportion of the population in a city that has convenient access to public transport. UN SDG 11 is "make cities and human settlements inclusive, safe, resilient and sustainable". Improving access to public transport services is integral to achieving the objectives of SDG 11. According to the UN Sustainable Transport, Sustainable Development 2021 Interagency Report, "only about half the world's urban population have convenient access to public transport". The report highlights that access to sustainable transport can help reduce food insecurity, boost economies, empower women, and connect people to key health, education, and financial services. As one measure of progress towards SDG 11, the UN has established SDG indicator 11.2.1. The indicator was computed as the proportion of WorldPop gridded population within either 0.5 kilometer walking distance to a low-capacity OpenStreetMap (OSM) public transport point or 1 kilometer walking distance to a high-capacity OSM public transport point. Cities were delineated using the European Commission Joint Research Centre (JRC) Urban Center Database (UCDB). The SDG indicator 11.2.1 data set provides estimates for the proportion of population with convenient access to public transport for 5,749 urban centers across 178 countries.

《可持续发展目标指标11.2.1：城市公共交通可及性，2023年发布版》，作为可持续发展目标指标系列的一部分，衡量城市中具有便捷公共交通可达性的居民比例。联合国可持续发展目标11的宗旨是‘使城市和人类居住区更具包容性、安全、韧性和可持续性’。提升公共交通服务的可及性是实现可持续发展目标11的关键。根据联合国可持续运输，可持续发展2021年跨部门报告指出，‘全世界大约只有一半的城市人口能够便捷地使用公共交通’。报告强调，可持续交通的可及性有助于缓解粮食不安全，推动经济增长，赋权女性，并将人们与关键的健康、教育和金融服务连接起来。作为衡量向可持续发展目标11迈进的一个指标，联合国设立了可持续发展目标指标11.2.1。该指标是通过计算WorldPop网格人口中，位于0.5公里步行距离内的低容量OpenStreetMap（OSM）公共交通点或1公里步行距离内的高容量OSM公共交通点的比例来计算的。城市边界是根据欧洲委员会联合研究中心（JRC）城市中心数据库（UCDB）划定的。可持续发展目标11.2.1数据集提供了178个国家中5,749个城市中心中，具有便捷公共交通可达性的居民比例的估计值。》
