Statistics Canada

Statistics Canada is the nation’s central statistical agency. It was established in 1918 as the Dominion Bureau of Statistics and adopted its present name in 1971. Under the Statistics Act of that year, it has the responsibility to “collect, compile, analyse, abstract and publish statistical information relating to the commercial, industrial, financial, social, economic and general activities and condition of the people.” The agency works with government departments to develop integrated social and economic statistics for Canada and the provinces and territories. In addition, Statistics Canada is a scientific research organization that develops methodologies and techniques related to statistics and survey design.

StatsCan Reports on Women

Women now make up slightly more than half of all people living in Canada. In fact, in 1991, the last census year, 50.4 per cent of the total population was female, compared with 50.2 per cent in 1981 and 48.4 per cent in 1921.This article was originally published in Maclean's Magazine on August 21, 1995

Stem Cell Research

Stem cells are the body's "building blocks"; they are the cells from which all tissues and organs are derived. They have the ability to divide while still maintaining their identity, yet they can also develop into specialized cells in response to certain stimuli. They can be found in a wide range of tissues in mammals at different stages of development and in adult organisms in tissues like nerve, muscle and skin. Stem cells from adults have a more restricted range of development. In order to develop new treatments for specific conditions scientists must understand more about how cell differentiation is directed by biological signals. New methods need to be found to grow large numbers of desired cells and more scientific experimentation involving different types of stem cells is vital. It will take many years for research projects to provide sufficient knowledge about stem cells to make new treatments possible (see Medical Research).

Sterilization of Indigenous Women in Canada

The practice of sterilization arose out of the eugenics movement and has a long, often hidden history in Canada. Sterilization legislation in Alberta (1928–72) and British Columbia (1933–73) attempted to limit the reproduction of “unfit” persons, and increasingly targeted Indigenous women. Coerced sterilization of Indigenous women took place both within and outside existing legislation, and in federally operated Indian hospitals. The practice has continued into the 21st century. Approximately 100 Indigenous women have alleged that they were pressured to consent to sterilization between the 1970s and 2018, often while in the vulnerable state of pregnancy or childbirth.

Stress

Stress was originally viewed as an overpowering external force acting upon individuals or objects. The mechanical engineer still uses the word in this sense, but human biologists have been less consistent in their terminology.

Sustainability in Canada

Sustainability is the ability of the biosphere, or of a certain resource or practice, to persist in a state of balance over the long term. The concept of sustainability also includes things humans can do to preserve such a balance. Sustainable development, for instance, pairs such actions with growth. It aims to meet the needs of the present while ensuring that future people will be able to meet their needs.
