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.
