Birth Seasonality in Present-Day Italy, 1993–2005

  • Matteo ManfrediniEmail author


Over the last century, Italy has undergone a dramatic change in its demographic regime. The high-pressure demographic system of the beginning of the twentieth century—high fertility, high mortality—has been replaced by a low-pressure system—low fertility, low mortality—although relatively recently in comparison to other Western European countries. Today, Italy has very low levels of fertility while life expectancy figures are amongst the highest in the world (Golini et al. 2000). The striking change in the demographic behaviour of Italians has generally been ascribed to the rapid social progress and economic development that occurred in Italy after the end of the Second World War.

One of the demographic issues that is possibly much affected by socioeconomic transformations as well as cultural changes, but has been little investigated for contemporary Italy, is birth seasonality. For earlier populations, birth seasonality has often been used as a useful indicator of the...
