SDG Indicator 9.1.1: The Rural Access Index (RAI), 2023 Release (2015-2022)(

The SDG Indicator 9.1.1: The Rural Access Index (RAI), 2023 Release data set, part of the SDGI collection, measures the proportion of the rural population who live within 2 kilometers of an all-season road for a given statistical area. UN SDG 9 is "build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation". Addressing inadequate access to roads, especially in rural areas, is critical to achieving SDG 9. According to the UN Sustainable Transport, Sustainable Development 2021 Interagency Report, sustainable transportation helps to eliminate poverty, promote food security, improve access to key health services, increase trade competitiveness, and bolster human rights. As one measure of progress towards SDG 9, the UN has established SDG indicator 9.1.1. The indicator was computed as the proportion of WorldPop gridded population within 2 kilometers to an OpenStreetMap (OSM) all-season road. The SDG indicator 9.1.1 data set provides estimates for the proportion of the rural population with access to all-season roads for 209 countries and 45,073 subnational units. The data set is available at both national and level 2 subnational resolutions.

SDG指标9.1.1：农村通达指数（Rural Access Index, RAI）2023版数据集，隶属于SDGI数据集合集，用于测算特定统计区域内，居住在全天候道路2公里范围内的农村人口占比。联合国可持续发展目标9（Sustainable Development Goal 9, SDG 9）的目标为“建设韧性基础设施、推动包容性可持续工业化并促进创新”。解决道路通达条件不足的问题，尤其是农村地区的道路通达难题，对实现SDG 9至关重要。依据联合国《2021年可持续交通与可持续发展跨机构报告》，可持续交通可助力消除贫困、提升粮食安全水平、改善关键医疗服务可及性、增强贸易竞争力，并强化人权保障。作为SDG 9进展评估的指标之一，联合国设立了SDG指标9.1.1。该指标的计算逻辑为：WorldPop网格化人口中，距离开放街道地图（OpenStreetMap, OSM）全天候道路2公里范围内的人口占比。SDG指标9.1.1数据集覆盖209个国家与45073个次国家行政单元，提供了上述区域内农村人口通达全天候道路的占比估算值。该数据集支持国家级与二级次国家级两种空间分辨率的数据获取。
