Random walk sampling

This form of sampling is used extensively in market research as a cheap approximation to true random sampling. The sample involves conducting random walks in small areas. These areas are usually wards within constituencies. First, a random sample of constituencies is drawn from a list of constituencies and then within each of the randomly selected constituencies a random selection of wards is chosen. Next, selected random starting points within these areas (wards) are chosen and interviewers are given fixed routes to follow and instructions to obey. The instructions specify the interval of households to contact (for example, every seventh house) and the action to take at each street junction (turn alternatively left or right). Special instructions are given about blocks of flats and what to do when non-residential buildings are encountered. Although the resulting sample is not truly random it is usually treated as if it were.
