    The increment rate is computed from the compound interest formula, taking as time intervals those between Census dates. We refer to resident population with current borders.

    In the first two censuses, the legal population of municipalities corresponds to the present population. In 1861 census, it was decided that Census forms must contain all the necessary elements to reconstruct the family and so the entitled population. This decision was taken in the light of an ongoing debate in statistical congresses on the suitability of defining the legal population from the principle of entitled or de facto population. A circular letter of 11 December 1863, addressed to the Reign of Italy prefects and vice-prefects, stated that the entitled population was made up, in each municipality, of all the present persons, minus the foreigners, and of the absents registered in the census forms. The reported value was published in a 1865 book edited by the General Statistical Directorate - Ministry of Agriculture, Industry and Commerce (Statistica del Regno d'Italia - Censimento generale 31 dicembre 1861 - Popolazione di diritto. Firenze, Tipografia letteraria e degli Ingegneri). In the 1871 census, the resident population figures were not published. The reported value was obtained by adding the permanently present and total absent population, as reported in the 1874 publication of the General Statistical Directorate - Ministry of Agriculture, Industry and Commerce (Popolazione presente e assente per comuni, centri e frazioni di comuni - Censimento 31 dicembre 1871, Volume I. Roma, Stamperia Reale).
