Statistical Significance

A difference between two estimates which is statistically significant indicates that it is very unlikely to have occurred due to chance alone.

Stillbirth rate

The number of births that are stillborn per 1,000 births (live or still).

Sulphur Dioxide

Sulphur Dioxide (SO2) is a gaseous oxide that results from the combustion of sulphur containing fossil fuels and also from the smelting of sulphur containing ores. Typically SO2 is emitted from electrical utilities and other industrial facilities. Sulphur dioxide is also a precursor to sulphate aerosols, commonly contained within fine and ultrafine particulate matter, and to the formation of acid rain.

Syphilis categories

A syphilis infection is categorized as primary, secondary, early latent, late latent or tertiary depending on the amount of time since the initial infection and the presenting symptoms.  During the primary, secondary and early latent stages, syphilis infections can be spread to others.  Late latent and tertiary infections cannot spread to others but may lead to significant health problems for the infected individual.

The Labour Force

People over the age of 15 years who are currently employed and those who are unemployed but were available to start work in the week prior to the Census and looked for work in the past 4 weeks. It excludes anyone who may have been without a job and was not actively looking for work.

Total Dependency Ratio

Number of people aged 65 years and older and children under the age of 20 divided by the number of people aged 20 to 64

Total Fertility Rate

The average number of children that would be born per woman if all women lived to the end of their childbearing years and bore children according to the age-specific fertility rates for that area and period.

Tuberculosis (TB) – active and latent infections

Active tuberculosis (TB) infection means that TB bacteria are present in a person’s body and are growing and causing symptoms.  If the active TB infection is the lungs or other parts of the airway, it can be spread to other people.  A latent TB infection means that TB bacteria are present in a person’s body, but his/her immune system is able to prevent the TB bacteria from growing.  Individuals with latent TB infection are not able to spread TB to others.


People over the age of 15 years currently without work, but who were available to start work and who had looked for work in the previous four weeks.  Anyone who had not looked for work in the previous four weeks is excluded. 

Visible Minorities

People who do not identify as Aboriginal, who are not Caucasian in race or not white in colour

What is the London Census Metropolitan Area (CMA)?

The London CMA includes the municipalities of London, St. Thomas, as well as Thames Centre, Middlesex Centre, Strathroy-Caradoc, Adelaide Metcalfe, Central Elgin and Southwold. The London CMA was one of 15 included in the study. There are 33 CMAs in Canada. 

What is the SES gap?

The 'gap' in health indicators was measured by a ratio of the rate in the low Socioeconomic status (SES) group to the rate in the high SES group. A ratio of 1.0 indicates no difference between the two groups. A ratio higher than one indicates higher rate of the disease or behaviour in the low SES group.

Why are deaths from 2007 the most recent being reported?

At the time of this resource, complete death data from Vital Statistics was only available for years up until 2007. The delay in releasing data results from the time required to ensure data quality. The delays for mortality data are longer than for other sources used in this resource, such as hospitalizations and survey data.

Youth Dependency Ratio

Number of children under the age of 20 divided by the number of people aged 20 to 64
