Not only does Singapore have a unique ethnic and multilingual makeup, it also boasts unique language policies, especially with regard to the learning of the official languages. Previous studies of Singaporean youths have largely focused on the differences in attitudes and code-switching between linguistic varieties (e.g. Colloquial Singapore English [Singlish] and Standard Singapore English) as well as looking at the specific languages of Singapore's multilingual community. This paper seeks to examine how Chinese-Singaporean youths differ in their perception of the benefits (general, communicative, cognitive and pragmatic) and disadvantages associated with Mandarin-English bilingualism and their Chinese-Singaporean identity. 165 Chinese-English bilingual youths from secondary schools, Polytechnics/Junior Colleges, University undergraduates and young working adults were stratified based their gender, socio-economic status and self-rated language proficiency. Our findings suggest that bilinguals' self-rated proficiency is generally the best indicator of local Chinese youths' attitudes towards Chinese-English bilingualism and identity, regardless of their current occupation, gender or socio-economic status.
