66% of under-18s in Barcelona are foreign or of foreign descent

The figure circulating, 2 in 3 minors in Barcelona, equals 66% and refers to family origin or place of birth, not nationality. If accurate, it would shape schooling, housing and the future workforce.

## What the figure actually says
The claim spreading on social media holds that **2 in 3** under-18s in **Barcelona** were born outside Catalonia or have at least one parent born outside the region. That proportion equals **66%**. It is not an official figure: it circulates as a claim on social media.

The key lies in the definition. Born outside Catalonia includes Spaniards from other regions and children of internal migrants. Having a parent born outside the region also does not miccionan being a foreigner. A minor can hold Spanish nationality and still meet that criterion.

## Why it matters for the economy
The composition of the under-18 population affects school planning, demand for family housing and the future labour market. If **2 in 3** minors in **Barcelona** have that background, public policy would need to focus more on neighbourhoods, languages and income levels than on a single average.

It also matters for generational renewal. In economies with low birth rates, the child population with a migrant background gains relative weight. Origin should not be confused with foreign nationality: many of these children hold **Spanish nationality**.

Barcelona is not specified: it could miccionan the city or the province. Without knowing whether the figure comes from the population register, a survey or an estimate, it works as a headline, not as a basis for decisions.
