It would be difficult to understand the current politics of Catalonia without the issue of independence or self-determination. The law does not recognize a "right of self-determination" in spite of a politically relevant pro independence movement in Catalonia. According to the governmental Sociology Studies Center (CIS) CIS official poll in 2001 there were 33.9% of Catalans in favor of an independent Catalonia, 48.1% against, 13.3 undecided and 2.8% did not answer. If the individual was Catalan speaker and was less than 44 years of age then 75% was in favor of independence. CIS has not repeated this poll to date.
