Births Statistics (NAIX). 2015. Provisional data


The number of live births registered in Catalonia in 2015 was 70,138, representing a decrease of 2.0% compared with 2014, according to provisional data of birth statistics.

The average age at maternity (31.9 years) has been delayed a year compared to 2005, due to the decline in fertility of young women and the increase of the fertility of women aged 35 years and over. The main increase was at ages 35 to 39, that, with 66 births per 1,000 women, it was consolidated as the second age group with more births in 2015 (after the group of 30 to 34 years).

By nationality, of the 70,138 live births, 17,842 were children of foreign mothers, representing 25.4% of live births, a rate much higher than the average for Spain (17.8%). By counties, stands La Segarra, with a percentage of 50.7% foreign mothers, and the municipality of Salt (among the largest municipalities of 20,000 inhabitants) with a percentage of 64.9%.

By territorial areas, the Girona Counties and El Camp de Tarragona were those with the highest birth rates, about 10 ‰. The lowest birth rates were recorded in L'Alt Pirineu i Aran (7.7 ‰) and Les Terres de l'Ebre (8.2 ‰). By counties, El Gironès (11.8 ‰), El Pla de l'Estany (11.2 ‰) and L'Alt Emporda (10.7 ‰) recorded the highest rates, while El Priorat (6.4 ‰) L'Alt Urgell (6.6 ‰) and L'Alta Ribagorça (6.9 ‰) had the lowest rates.

In relation to the number of children per woman, the Girona Counties, Ponent and Central Counties were the areas of the Territorial plan with the highest fertility rate (1.55, 1.50 and 1.49 children respectively) and L'Alt Pirineu i Aran (1.20 children) is the area that had lowest.

The Birth statistics provide information on the live births, deliveries and late foetal deaths of residents of Catalonia according to demographic, social and territorial characteristics (for the municipal, county, province levels and the areas of the Territorial Plan). Birth and mortality statistics conform a population's natural movement, providing for an estimate of the natural growth of the population as the difference between the number of births and the number of deaths.

The source of the data are the statistical bulletins on the births by women residents of Catalonia that have been registered in its civil registers. Until 2011, the data only referred to the registrations of women who resided in Catalonia. After 2012, the data has been released in two phases: the provisional data, with the births by women registered in Catalonia, and the definitive data, with the births by all women residents, including those who may be registered in other autonomous communities.
