The statistics included in the BC Community Health Profiles come from different data sources with different sampling methodologies.
Municipal data do not include data from neighbouring First Nations reserves, though it may include off-reserve First Nations people residing within the municipal boundary. See page 1 of each profile for a map outlining the boundary for municipal data.
Data presented at a larger geographic area (e.g., your local health area) include all communities within the specified region, unless otherwise stated in the
data_source_descriptions (e.g., Early Development Instrument data and School Satisfaction Survey data). See page 5 of each profile for a map outlining the boundary for your local health area.
The National Household Survey (NHS) was introduced in 2011 as a replacement for the long census questionnaire to collect social and economic data about the Canadian popualtion. There are notable differences between the NHS and Census in terms of sampling and data collection methodology, and unlike the mandatory long census questionnaire, NHS is a voluntary sample survey. Therefore, comparison of results obtained from NHS 2011 to those from Census in previous years is cautioned.
