Special issues in sampling ethnic minorities and migrants
27 April 2010, 5:00pm, at the Royal Statistical Society
Approximately one in 12 British households includes one or more ethnic
minority residents. Because such households do not appear on separate
lists, samples of ethnic minorities are generally identified by means of
large address screening exercises. Because these exercises are expensive,
special sampling procedures have been developed to minimise their costs.
One such method is to concentrate fieldwork in areas where ethnic minorities
are known, from Census data, to be concentrated. Another method (commonly
used in conjunction with this) is to screen addresses by proxy using
information provided by neighbours – the method of focused enumeration.
Typically, where large samples of ethnic minorities have been required for
large Government surveys (eg BCS, the CLG Citizenship Survey, the Health
Survey for England, The Offending, Crime and Justice Survey both methods
have been used. This seminar will focus on two issues relating to this
general approach.
Dr James Brown will describe a modelling approach that has recently been
developed to identify areas of high migrant concentration which takes into
to account the fact that many migrants will have come to Britain since the
2001 Census.
Patten Smith, Kevin Pickering and Joel Williams will present preliminary
results of a recent investigation of the efficacy of Focused Enumeration –
to our knowledge the first to be conducted since the method was developed in
1981.
The discussant will be Susan Purdon who is a partner in Bryson Purdon Social
Research.
