ONE-SIXTH of Spanish citizens were born to either a foreign mother or father, according to data from the National Institute of Statistics (INE).
The INE’s Continuous Household Survey showed around 16.9 per cent of Spanish citizens had at least one parent born outside of Spain, or more than 7.8 million people.
The amount has risen from almost 7.3 million in 2013, when the proportion stood at more than 15.7 per cent.
Celia Marcen, Professor of Sociology at Zaragoza’s San Jorge University, said the figures showed cultural and national identities were becoming blurred for more Spanish people.
“It is increasingly difficult to define what it means to be Spanish, or Aragonese, or any other identity, which is a global phenomenon,” Marcen said.
INE data also showed the population of Spanish citizens born to at least one foreign parent has grown by almost 10.8 per cent since 2013. The population growth of the whole of Spain during the same period was 0.2 per cent.
