社会科学家越来越多地使用根据气象卫星记录计算的夜间灯光，作为发展中国家国家以下地区经济活动或经济发展的替代指标，因为这些地区无法获得统计局的分类数据。然而，到目前为止，我们对这些国家夜间灯光捕捉的内容的了解有限。我们使用来自29个非洲国家的地理参考人口与健康调查（DHS），为DHS集群位置以及大约50 × 50 km的网格单元构建家庭财富，教育和健康指标。我们发现，夜间灯光与这些特定位置的人类发展指标呈正相关，夜间灯光的变化可以解释这些指标变化的很大一部分。我们的结论是，夜间灯光是一个很好的代理人在地方一级的人类发展。
Nighttime lights, calculated from weather satellite recordings, are increasingly used by social scientists as a proxy for economic activity or economic development in subnational regions of developing countries where disaggregated data from statistical offices are not available. However, so far, our understanding of what nighttime lights capture in these countries is limited. We use geo-referenced Demographic and Health Surveys (DHS) from 29 African countries to construct indicators of household wealth, education and health for DHS cluster locations as well as for grid cells of roughly 50 × 50 km. We show that nighttime lights are positively associated with these location-specific indicators of human development, and that the variation in nighttime lights can explain a substantial share in the variation in these indicators. We conclude that nighttime lights are a good proxy for human development at the local level.
