Chronic Obstructive Pulmonary Disease: Morbidity

Chronic obstructive pulmonary disease: Estimated prevalence by current occupation, U.S. working adults, non-smokers aged 18 and over, 2004–2011
Table showing Chronic obstructive pulmonary disease: Estimated prevalence by current occupation, U.S. working adults, non-smokers aged 18 and over, 2004–2011

† Estimates with a relative standard error of greater than 50% are suppressed.
– Estimated confidence intervals not calculated because estimated prevalence of chronic obstructive pulmonary disease (COPD) among workers in this occupation is zero.
a Estimates with a relative standard error of more than 30% but less than or equal to 50% are statistically unstable due to small sample size and should be used with caution as they do not meet the standards of reliability.
b No non-smokers in this occupation from 2004 to 2011. Prevalence estimate and confidence interval are not calculated ("na" = not applicable).

Note:  Numbers presented are average annual estimates for the period 2004–2011. Prevalence estimates are weighted and are not age–adjusted. Non-smokers are those who had never smoked or those who smoked less than 100 cigarettes during their entire life. Working adults are those who were employed in the week prior to the survey. Estimated populations represent current U.S. workers aged 18 years and over by occupation. Estimated totals do not add up due to rounding.
