Note(s):
Total household population aged 3 to 79, except those
meeting the exclusion criteria (see the Canadian Health Measures Survey
(CHMS) Data User Guide: Cycle 2). The sample size for 3 to 5 year
olds produces reliable national estimates for both sexes combined only. Results
are substituted by the lower limit of detection divided by 2 in
cases where the result is below the lower limit of detection.
