This dataset, provided by the Italian National Institute of Statistics through its I.Stat portal, presents fertility estimates for the entire country along with each NUTS macroregion and Italian region. Estimates are available for the total fertility rate, age-specific fertility rates by mother's age or father's age, and citizenship. The estimates are created using live births registered in the country's population register; migration and calculation of yearly resident population; resident municipal population by age, sex and marital status; migration and calculation of foreign resident population and structure by citizenship; and municipal resident foreign population by sex and year of birth.
