"A concussion is a type of traumatic brain injury. It is caused by a bump, blow or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth. This sudden movement can cause the brain to bounce around or twist in the skull, creating chemical changes in the brain and sometimes stretching and damaging brain cells.”1

Confidence Intervals

Confidence intervals (CIs) indicate the reliability of a statistical estimate or rate.  A 95% confidence interval is interpreted as a range in which we can be 95% confident the true population value lies. Wide confidence intervals, suggest less reliable estimates than narrow confidence intervals. In general, the larger the population, the narrower the CI and hence, the more precise is the estimate. Confidence intervals can also be used as tests of statistical significance when comparing estimates – if the CIs for the estimates under comparison overlap, we can say the difference between the estimates is not statistically significant. For CCHS data, 95% CIs have been calculated using the “bootstrap method”.

Current Smoker

Smokes cigarettes at the present time, including daily and occasionally.

Dependency Ratio

The ratio of the combined child population aged 0 to 19 and population aged 65 and over to the population 20 to 64 years old.

The population aged 65 and over and those under age 20 are more likely to be socially and/or economically dependent on the working aged population, and they may also put additional demands on health services. This ratio is presented as the number of dependents for every 100 people in the working age population.1

Dissemination Area

A small geographic area with a population of 400 to 700 persons. All of Canada is divided into dissemination areas which are used to report Census information.

Elderly Dependency Ratio

Exclusive breastfeeding

When an infant is only fed breast milk, and no other formula, water, substitute, or food is given.

Folic acid use prior to and during pregnancy

The percentage of women who gave birth (live or still) who reported taking folic acid supplements prior to and during pregnancy. Excludes women who did report any use during pregnancy (i.e., use only reported prior to pregnancy).

Folic acid use prior to pregnancy

The percentage of women who gave birth (live or still) who reported taking folic acid prior to pregnancy. Includes women who reported any folic acid use prior to pregnancy (including those who continued use during pregnancy).

Food Handler Certification Program

A program designed to teach food handlers the general principles of safe food handling such as risk factors associated with food borne illness and to teach the skills necessary to handle food and prevent illness from occurring. The course is based on the principles of sanitary food service and hazard analysis critical control point (HACCP) procedures. 

Food Security

Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. The CCHS survey questions asked whether household members were able to afford the food they needed in the previous 12 months. Households were classified as food insecure if there was an indication of compromise in quality and/or quantity of food consumed or reduced food intake and disrupted eating patterns due to lack of money.

General Fertility Rate
