The actual number of vines by variety and age grouping and the total acres planted were requested. Response Rate A total of 441 growers responded of the 579 contacted. This translates into a 76 percent response rate. The responding farms accounted for 94.6 percent or 39,373 tonnes of the total 41,619 tonnes reported by the processors. Expanding the Sample Data To analyse the retrieved information from the survey, a factor of total tonnage compared to that of the sample was used to expand the results.

The format of this publication has been changed to simplify the presentation of the results. Tables identifying the number of vines are presented in the appendices. A tabulation has been done comparing the results of this survey with prior census results by variety. Separate tabulations are given by variety, age grouping and district. There was an increase in the total number of vines in Ontario in 1996 from 1991.
