Ethnicities of Iberia on a Map

Ethnicity can be complicated since it's based on self-identification. From what I researched, it looks like ethnicity is most closely to language in Spain, so this map is mostly based off of distinct languages and dialects. However, it seems that people in different places have different ideas on how independent they are from the main "Castilian" culture of Spain. For example, many Basques and Catalans want full independence/autonomy from the Spanish government; other groups, like Andalusians and Extremadurans, still have strong regional identities but may not necessarily see themselves as a distinct from the rest of Spain. Also, there's a lot of debate in Spain as to what constitutes a separate language and what constitutes dialects of Spanish or Catalan .

That all being said, if anyone thinks they can make a better map, go right ahead. This is just what I came up with based on my research/maps.
