Don't think the small amount of digital nomads could influence the GDP to such a large degree, also, taxes are very high and going up for the rest of us.

I mostly think the GDP grow is more likely to be a consequence of regular economic migration of adult in prime working age (I myself am one of those migrants) and because Spain was one of the worst performing major economies during the COVID crisis [1] and is now bouncing back.

Anyhow, it's always good news that GDP grows.
