1. Data source: Statistics Canada, Canadian Community Health Survey, 2003
2. Population aged 12 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. "Health regions" are defined by the provincial ministries of health. These are legislated administrative areas in all provinces except Nova Scotia. In Nova Scotia, the Ministry of Health uses statistical "zones" rather than its legislated administrative areas; the zones are aggregations of the nine district health authorities.
7. For complete Canadian coverage, each of the northern territories also represents a health region.
8. The health regions presented in this table are based on boundaries and names in effect as of June 2003.
9. A "peer group" is a grouping of health regions that have similar social and economic characteristics. The nine peer groups are identified by the letters A through I, which are appended to the health region 4-digit code.
10. In Ontario, Public health units (PHU) administer health promotion and disease prevention programs, and District health councils (DHC) are advisory, health planning organizations.
11. In Manitoba, Saskatchewan and Alberta, health regions are referred to as Health Authorities (HA) or Regional Health Authorities (RHA).
12. To avoid data suppression, northern regions in Manitoba have been grouped with neighbouring regions, as follows: Churchill Regional Health Authority (4690) is combined with Burntwood Regional Health Authority (4680) and referred to as "Burntwood/Churchill (4685)".
13. To avoid data suppression, northern regions in Saskatchewan have been grouped with neighbouring regions, as follows: Athabasca Health Authority (4713) is combined with Mamawetan Churchill River Regional Health Authority (4711) and Keewatin Yatthé Regional Health Authority (4712) and referred to as "Mamawetan/Keewatin/Athabasca (4714)".
14. The following standard symbols are used in Statistics Canada publications: (..) for figures not available for a specific reference period and (...) for figures not applicable.
