How the commuters move: a statistical analysis based on Italian census data

The matrix of commuting, built from Census data, provides information on daily movements from the municipalities of residence to work or study place. The territorial detail considered in the matrix (available on the Istat website) is the municipality inside of which commuters are stratified on the basis of some relevant variables. In the present paper, using such matrices, we try to identify types of commuters that differ in terms of commuting according to the dimension of the municipalities: below and above 20,000 inhabitants. The methodology used is the two step cluster analysis.
