“…To give some examples of their use in social sciences, centrographic measures have been used to analyze the spatial patterns of automobile accidents in Honolulu (Levine et al 1995), the dynamics of local labour markets and the mobility patterns of elderly residents in the Quebec City Metropolitan Area (Barbonne et al 2007;Lord et al 2009), the relocation of logistic terminals in the Paris Metropolitan Area (Dablanc and Rakotonarivo 2010), the evolution of the American population by religious affiliation (Crawford 2005), the employment pools of commuting women and men using various transport modes and having different family structures (Vandersmissen et al 2011), and the spatial dispersion of retail stores in Changchun, China (Wang et al 2014). Centrographic analysis has also been used in natural sciences, for instance, to describe the spatial distribution of mineral deposits (Mamuse et al 2009), to identify the potential alignment of underlying geological structures through the spatial characterization of volcanic events (Bishop 2007), and to recommend The Canadian Geographer / Le G eographe canadien 2018, xx(xx): 1-14 A method to test the significance of differences 3 328 Marco A.
