Why do we ask for the person with the last birthday?
Many research companies use this method to make sure that their selection of people to do their survey
is random. By asking each time for the person with the last birthday in the household, Scarborough
obtains a strong cross-section of age, gender, education, income, etc. This method of selecting people to
complete our survey in turn ensures that all types of people will be well-represented in the survey.
