Liberia urbanization metrics

Defining what is and is not urban is complicated, but is crucial to many aspects of development: poverty estimation, disaster mitigation, quantifying environmental degradation, just to name a few. While official definitions of urban are usually left to nectral statistical agencies, there is need for a consistent, quantitative, apolitical definition of urban. This data package attempts to do that by estimating urban in three different ways: using nighttime lights, using gridded population data, and a combination of gridded population data and travel time. Within these defintions, a number of econometric, demographic, and morphological metrics are calculated, all of which are based on open source data and analytics.
