The ISSP National Identity module consists of two surveys from 1995 and  from 2003. The 2003 survey was a partial replication of the 1995 study.  

The ISSP National Identity module mainly deals with respondents’ identification(s), aspects of national pride and support for his/her own nation, attitudes towards national and international issues, attitudes towards foreigners and foreign cultures, and views on what makes someone a true member of his/her nationality.
