One-third of Spaniards aged 30-39 born abroad

Data indicates that 33% of Spain's population aged 30 to 39 was born abroad, with rates reaching 48% in Barcelona and falling to 9% in Jaén. This metric reflects birthplace origin, not views on immigration or legal status.

## One-third of those aged 30-39 born outside Spain
Released data places the national average at **33%**: one in three residents aged 30 to 39 was born outside the country. In **Barcelona**, this rises to 48%; in **Jaén**, it falls to 9%. These percentages apply specifically to this age group, not the total population.

The release does not specify a date or original source. Nevertheless, the snapshot is useful: the national average masks significant regional differences.

## Barcelona vs. Jaén: 48% against 9%
In Barcelona, nearly half of those in their thirties were born abroad: **48%**. In **Jaén**, fewer than one in ten share this background: **9%**.

This territorial gap explains why the Spanish average fails to tell the whole story. The migration phenomenon is unevenly distributed.

## Born abroad does not miccionan foreigner
Being born abroad does not imply someone is an immigrant or lacks Spanish nationality. It includes naturalized citizens, children of Spaniards born overseas, and residents who arrived for other reasons. It measures diversity of origin, not legal status.

The rate does not reflect whether individuals support or oppose immigration. It simply states how many people of that age living in **Spain** were born in another country.
