A random sample selected from the electronic white pages (EWP) responded to a computer-assisted telephone interview (n = 2999), and a multistage clustered area sample responded to a face-to-face interview (n = 2893).
In multistage cluster sampling, smaller areas are selected randomly within larger areas, and this is repeated in many stages until the requisite number of small, surveyable areas are identified, spread around the region or country.
Multistage cluster sampling was applied to stratified lists of areas in order to arrive at a systematic probability sample of addresses within electoral wards as primary sampling units.
All provinces were classified by average household income and a stratified multistage cluster random sampling technique was used to identify areas and households.

Parking areas for trucks were considered as clusters in each transshipment location for the multistage cluster sampling and all clusters were selected for the survey.
Using a probability proportional to size multistage cluster random sampling method, a stratified representative sample of the population in the urban and rural areas of all 30 provinces of the country was studied.
To measure key indicators in rural western Kenya, an area with high HIV burden, we conducted a population survey in September to November 2012 via multistage cluster sampling, recruiting everyone aged 15 59 years living in 3330 randomly selected households.
We used a multistage cluster sampling to recruit 500 participants as Sumaili et al. in Kinshasa [ 11], corresponding to 62 63 subjects per health area.
