Data sources and methodology
This is a sample survey with a cross-sectional design.
For each province, lists of telephone numbers in use were purchased from the telephone companies and lists of working banks were extracted. Each bank was assignet to a stratum within its province. A random sample of telephone numbers was generated in each stratum (from working banks). An attempt was made to generate the entire sample of telephone numbers on the first day of interviewing. Therefore, a prediction of the percentagle of numbers dialled that would reach a household had to be made (this is known as the "hit rate"). The hit rate was estimated using information from previous RDD surveys, specifically the General Social Survey, Cycle 8. For this survey, 46.1% of the numbers dialled reached households. An attempt was made to conduct a CADS interview with one randomly selected person from each household.
