Urbanization and Child Nutritional Outcomes
利用卫星夜间灯光数据衡量城市化程度，结合尼日利亚2008和2013年人口健康调查数据，研究城市化对儿童营养结果的影响。
In this paper, the relationship between urbanization and child nutritional outcomes is investigated using satellite-based nighttime light intensity data as a proxy for urbanization and urban growth. Geo-referenced and nationally representative data from two rounds (2008 and 2013) of the Demographic and Health Survey (DHS) from Nigeria is employed. The DHS data provide detailed anthropometric measures of child nutritional outcomes along with a series of control variables. These geo-referenced DHS data are merged with nighttime light intensity data for the survey clusters in which the DHS sample households reside. This nighttime light introduces a gradient of urbanization permitting investigation of the implications of urbanization on child nutritional outcomes along an urbanization continuum.
