NPHS (National Population Health Survey)


The NPHS collects information related to the health of the Canadian population and related socio-demographic information. It is composed of three components: the Households, the Health Institutions, and the North components.

The Household component started in 1994/1995 and is conducted every two years. The first three cycles (1994/1995, 1996/1997 and 1998/1999) were both cross-sectional and longitudinal. Beginning in Cycle 4 (2000/2001) the survey became strictly longitudinal (collecting health information from the same individuals each cycle).
