Scatter plot of the number of orders of magnitude spaned by the voting populations of a precinct as a function of the number of municipalities in each precinct, for 2015 (a) and 2016 (b). We find a positive correlation with suggesting that the “size” of a precinct in terms of the number of municipalities explains 47% of the variation in the support (in terms of orders of magnitude) of the number of votes (the larger the number of municipalities is, the more likely the number of votes takes values from a larger number of orders of magnitude). The coefficient of 0.004 indicates that, on average, when we move from a precinct with municipalities to one with , the ratio of the biggest population to the smallest is 2.5 times bigger.
