Sorin Cosoveanu sent me the information that now appears in the change history, from source [1].

I updated the population data using a file from UPECEDS (Ufficio Programmazione Economica - Centro Elaborazione Dati e Statistica = Economic Programming Office - Data Processing and Statistics Center). These figures appear to be computed from municipal population registers. Thanks to Sorin Cosoveanu for bringing them to my attention.
