Territorial grids in the Mediterranean: space versus population

This paper explains how to make international comparisons on a Mediterranean scale for demographic and geographical themes. This study deals with the variability observed of surfaces and populations of the grids available of the Mediterranean countries. First, we wonder what makes the relevance of a grid compared to another. Then, we use spatial autocorrelation as an indicator of spatial and statistical characteristics of a grid for a specific variable. We create two grids for the occasion. Comparing several grids, we explore the variability generated by the variable of population density. The results show the importance of this kind of approach before beginning any international comparison. They also remind the importance of MAUP in spatial studies.
