For the first time in 2001 the Census for England and Wales included a question on religious identity. The campaign for the inclusion of this question was largely pioneered by the Muslim community who argued that religious identity was a more significant indicator of social and public significance than ethnicity. This paper tests the thesis that Muslim identity predicts distinctive values of public and social significance among male adolescents (13-15 years of age) who participated in a survey conducted across the four nations of the United Kingdom. From the 11,870 participants in the survey the present analysis compares the responses of 158 male students who self-identified as Muslim with the responses of 1932 male students who self-identified as religiously unaffiliated. Comparisons are drawn across two domains defined as religiosity and as social values. The data demonstrated that for these male adolescents self-identification as Muslim encased a distinctive profile in terms both of religiosity and social values.
