Distribution of the concentration of o-xylene measured in indoor air for the household population by age and sex, Canada, 2009 to 2011
Table summary
This table displays the distribution of the concentration of o-xylene measured in indoor air for Canadians 3 to 79 years of age. The row headers provide information for each age group overall and by sex. The column headers provide the estimate and confidence interval for the geometric mean, as well as the 5th, 10th, 25th, 50th, 75th, 90th and 95th percentiles.

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.
