The table shows the changes in self-rated health
of the 1994/1995 household population aged 12 and over
every 2 years from cycle 1 to cycle 6 of the
National Population Health Survey. Population, age, sex, Canada and province
are based on the first survey cycle (cycle 1) in 1994/1995. |
| 2. |
The table excludes persons who died or who
were institutionalized after cycle 1 survey interview in 1994/1995.
Estimated number of persons who have died: 287 persons after cycle 2, 599 persons
after cycle 3, 957 persons after cycle 4, 1,279 persons
after cycle 5 and 1,640 persons after cycle 6. These
data are not all confirmed yet with the Canadian Vital Statistics Database.
Persons living in an institution are excluded because they are not asked certain
questions. Estimated number of persons who have been institutionalized: 62 persons
at cycle 2, 114 persons at cycle 3, 135 persons
at cycle 4, 161 persons at cycle 5 and 144 persons
at cycle 6. |
| 3. |
The table also excludes children under 12 and
non-response (missing values), that is, "not applicable", "don't know", "refusal"
and "not stated". |
| 4. |
No estimates for self-rated health are provided
for 1994/1995; what is shown instead are the changes in self-rated health.
For estimates on self-rated health in 1994/1995, please refer to Health
Indicators CANSIM table 104-0022, "Health status, Well-being". |
| 5. |
Percentages are based on the population with
a specific characteristic (one category) in a given cycle as the numerator
divided by the total population in 1994/1995 having all possible
characteristics (all categories) as the denominator, excluding missing values.
|
| 6. |
Bootstrapping techniques were used to produce
the coefficient of variation (CV) and 95% confidence intervals (CIs).
|
| 7. |
Data with a coefficient of variation (CV) from 16.6%
to 33.3% are identified by an (E) and should be interpreted with caution.
|
| 8. |
Data with a coefficient of variation (CV) greater
than 33.3% were suppressed (F) due to extreme sampling variability. |
| 9. |
Changes in self-rated health of the 1994/1995 population
during each consecutive survey cycle from 1994/1995 to 2004/2005 are
based on the 2004/2005 longitudinal full cycle 1 to cycle 6 subset
of respondents (from 2004/2005 longitudinal data file). This subset
contains all panel members with a complete (full) response in cycle 1 (1994/1995),
cycle 2 (1996/1997), cycle 3 (1998/1999), cycle 4 (2000/2001),
cycle 5 (2002/2003) and cycle 6 (2004/2005). Number of
respondents for this table (excluding missing values): 8,525. |
| Note(s): |
When comparing estimates, it is important to use confidence intervals
to determine if differences between values are statistically significant.
Confidence intervals describe sampling variability and give an indication
of the precision of a given estimate. Please note that confidence intervals
and coefficient of variations are provided in the CANSIM tables. |
