Methodological note

Definition of concepts

Average maternity age
Average age at which children are born to mothers, weighted by rates at each age. The numerator is the sum of the product at each age for each of the fertility rates and the denominator, the sum of the rates.
Short-term fertility rate (average number of children per woman)
Reference number that is calculated by adding the fertility rates per age and represents the number of children that a generation of women would have if the fertility rates per age were to remain stable as observed at any given moment. The number of children actually born to generations of women fluctuates less than that calculated by the short-term indicator, which is highly sensitive to changes in the fertility "calendar" (for example, a rejuvenation of the average age of mothers leads to a major increase in the indicator, while a delay in the average age implies a sharp decrease).
Fertility rate
Live births per 1,000 women of each age.

Methodological aspects

The Births Statistics provide information on the births, deliveries and late foetal deaths of people residing in Catalonia according to their demographic and social characteristics.

The original source of the data is the Statistical Bulletin of Births (BEP), filled in by the parents or persons obliged by law to declare the birth or, if this is not possible, by the civil registrar.

The data include all births of women residing in Catalonia, both those registered in the civil registers of Catalonia and those registered in the civil registers of other autonomous communities. In 2011 and previous years, the data refer only to births of women residing in Catalonia registered in the civil registers of Catalonia.

From 2012 onwards, as well as births by resident mothers taking place within Catalonia, this also includes births by mothers resident in Catalonia taking place in other autonomous communities.

The data are disseminated annually in two phases: provisional data and definitive data, which incorporate a greater exhaustiveness of the file and the filtering of the main variables.

Idescat compiles this statistical operation in collaboration with the INE.
