| 1. | Data source: Statistics Canada, National Population Health Survey, 1996/97, cross sectional sample, health file |
| 2. | Population aged 65 and over who reported when they had their last influenza immunization (flu shot). |
| 3. | Bootstrapping techniques were used to produce the coefficient of variation (CV) and 95% confidence intervals (CIs). |
| 4. | Data with a coefficient of variation (CV) from 16.6% to 33.3% are identified by an (E) and should be interpreted with caution. |
| 5. | Data with a coefficient of variation (CV) greater than 33.3% were suppressed (F) due to extreme sampling variability. |
| 6. | Comparable data are not available for 1994/95 and 1998/99. |
