AuthorsPeter Lynn, Alita Nandi, Violetta Parutis and Lucinda Platt
OBJECTIVE: To describe the design and implementation of a nationally representative probability sample of immigrants and ethnic minorities in the United Kingdom.
METHODS: We boosted a nationally representative sample by using small-area census data to identify areas that covered the majority of immigrant and target ethnic minority populations and oversampled addresses from those areas using varying sampling fractions. Households were screened for eligibility based on whether they included a target immigrant/ethnic minority member. If so, all adult members were interviewed.
RESULTS: We anticipated the main challenges would be: fewer eligible households than predicted in sampled areas due to geographical mobility; refusal of those screened to provide information on household eligibility; nonparticipation of eligible households. All these issues were found to some degree. We describe how we addressed them and with what success.
