  We study the parametric description of the city size distribution (CSD) of 70
different countries (developed and developing) using seven models, as follows:
the lognormal (LN), the loglogistic (LL), the double Pareto lognormal (dPLN),
the two-lognormal (2LN), the two-loglogistic (2LL), the three-lognormal (3LN)
and the three-loglogistic (3LL). Our results show that 3LN and 3LL are the best
densities in terms of non-rejections out of standard statistical tests.
Meanwhile, according to the information criteria AIC and BIC, there is no
systematically dominant distribution.
