Distance to the scaling laws evaluated for the urban indicators versus the distance evaluated for the number of homicides.

<p>Scatter plot of the distances to the scaling laws evaluated for the urban indicators () versus the distance evaluated for the number of homicides (). The color code represents the density of points, going from blue (low density) to red (hight density). We show in each plot the value and the 95% confidence intervals for the Pearson correlation coefficient . We note that evaluated for GDP, GDP per capita, income, and male population are positively correlated with , while related to child labour, elderly population, female population, illiteracy, sanitation, and unemployment are negatively correlated with . We further observe the bimodal distributions of the relationships for GDP, GDP per capita, illiteracy, and income.
