Fig. 4: Gender differences in visit patterns.
Gender ratio ρF/ρM as a function of the bandwidth d (decimal logarithm of the value in decimal degrees), for a few selected POI types, including the "towers’‘ and "uniform” reference layers (a). The vertical line corresponds to a kernel bandwidth comparable to the spatial resolution afforded by the CDR data we use. The gender ratio ρF/ρM as a function of the bandwidth d is compared to two reference null models for “taxi” (b), “hospital” (c), and “mall” (d). The shaded area indicates, for each value of the bandwidth d, the 95% confidence interval of the values ρF/ρM computed on the realizations of the spatial sampling null model. The dashed line indicates the gender ratio computed on the spatially perturbed null model.
