This paper summarises findings from a research study which investigated how 11- to 17-year-old mixed-heritage adolescents living in London negotiate the demands of living with multiple cultures. The study also explored how these adolescents construe themselves in terms of race, ethnicity and nationality. It was found that these individuals had multiple identifications which were subjectively salient to them, and that they were very adept at managing their various identities in different situations. There was no evidence of a sense of marginality, or of being ‘caught between two cultures’, and there was no difference in the strength of British identification exhibited by these mixed-heritage adolescents and white English adolescents of the same age. However, the identities and cultural practices of the mixed-heritage adolescents were fluid and context-dependent, and they appreciated the advantages of being able to negotiate and interact with multiple ethnic worlds.
