The newest version of Vancouver’s retail product measurement study will be released Jan. 27.

Produced by ComQuest Research Group, a division of BBM Bureau of Measurement, the study is the latest in a series that began in 1988.

The study uses a combined diary for radio, tv, newspaper and other media, with more than 1,000 categories of consumer behavior in the Vancouver extended market.

The sample base used had 2,790 respondents, 681 of them outside the Vancouver central market and was distributed randomly to represent the region.

Within the Vancouver central market, there were 2,109 respondents. Overall, the database represents more than two million individuals.

Fieldwork for the study took place in the fall of 1992, coincident with the fall radio sweep.

The sampling plan was weighted to adjust the sample to correct proportions, an approach similar to bbm’s usual way of sampling this market. DC
