Has the Middle Class Grown in Ecuador? An Analysis Using Income Polarization Indexes for the Period 2007 to 2014

The results show that polarization have steadily decline between 2007 and 2014 due to an homogeneous move from lower income class households to higher income classes, which translates into an increase of the middle class measured as proportion of the total population.
