Start page 190 End page 206 Language eng Abstract One emerging application of night-time light imagery focuses on estimating levels of access to electricity globally (Doll & Pachauri, 2010; Elvidge et al., 2010). A central consideration of such studies is the population density which can be consistently detected from night-time light imagery. Whilst numerous studies have addressed the relationship to light and population statistics in order to predict population, the use of spatially explicit population databases allows for a more detailed description of these relationships. This paper reports the variation of different detection profiles of two publically available gridded population datasets. These are disaggregated by region to reveal a vast contrast in what we may assume to be observable population in different parts of the world. A dynamic trend emerges with respect to levels of development with the most developed nations hypothesized to be the theoretical minimum observable population density. Beyond contributing to the analysis of areas of the world without access to electricity, more fundamentally, this analysis addresses a basic question about night-time lights and how it relates to population globally and in particular the relative merits of two commonly used population databases.
