Seeing the list of national identity potential determinants interviewees were asked which are necessary to deem somebody a Pole. Only 2% of interviewees were not able to point out any determinants. The most often chosen national identity indicator was self-identification i.e. identifying oneself as a Pole. The second most commonly chosen criteria was having Polish citizenship. Catholicism as a necessary determinant of being Polish was the least often chosen from the list of indicators.

More on that issue can be found in the CBOS report in Polish: „National Identity and Perception of National and Ethnic Minorities”.
