Figure 1. Percentage of smokers and former smokers living in multiunit housing (MUH) whose buildings have smoking bans and who are exposed to secondhand smoke (SHS) in their homes, 2013–2015, by country. Percentages for “complete smoking ban in MUH” and “no MUH smoking ban/ban in shared areas only” were based on a subset of current and former smokers who lived in MUH in each country in 2013–2015 (n = 2,446); percentages were estimated by using a multinomial logistic regression model. Percentages for “smoking not permitted in home in MUH building allowing smoking” were based on the subset of current and former smokers who were living in MUH but whose building did not ban smoking completely (n = 1,632). Percentages for “any SHS incursion,” “weekly SHS incursions,” and “daily SHS incursions” were based on a subset of current and former smokers living in MUH where smoking was not banned but who had complete smoking restrictions in their own homes (n = 393). All remaining percentages were estimated using logistic regression. All percentages were adjusted for sex, age group, smoking status, income, education, children living in the home, wave of recruitment, and survey mode. Error bars indicate 95% CIs.
| Country | Complete ban, % (95% CI) | No ban/ban in shared areas only, % (95% CI) | Smoking not permitted in home, % (95% CI) | Any SHS incursion, % (95% CI) | Weekly SHS incursions, % (95% CI) | Daily SHS incursions, % (95% CI) |
|---|---|---|---|---|---|---|
| United States | 28.7 (24.7-33.2) | 63.9 (59.1-68.5) | 32.3 (27.3-37.7) | 29.9 (20.4-41.5) | 22.3 (13.7-34.0) | 11.2 (6.7-18.3) |
| Canada | 28.8 (24.2-33.8) | 67.0 (61.8-71.7) | 29.6 (24.9-34.8) | 38.4 (26.7-51.6) | 17.9 (9.1-32.3) | 6.4 (2.4-16.2) |
| United Kingdom | 26.1 (22.7-29.9) | 68.3 (64.4-71.9) | 20.4 (16.7-24.7) | 24.7 (15.7-36.7) | 15.5 (8.5-26.5) | 9.6 (4.1-20.7) |
| Overall | 27.8 (25.5-30.2) | 66.3 (63.7-68.8) | 27.0 (24.2-30.0) | 30.8 (25.1-37.2) | 19.2 (14.5-25.0) | 9.6 (6.6-13.8) |
Figure 2. Preference for complete bans on smoking among smokers and former smokers living in multiunit housing (MUH) (n = 2,168) in the United States, Canada, and the United Kingdom, 2013–2015. “Slightly prefer,” “somewhat prefer,” and “strongly prefer” were combined to form the overall “would prefer a complete smoking ban in MUH” category. The overall percentage who “would prefer” complete bans was estimated by using logistic regression, whereas the percentage who would “slightly prefer,” “somewhat prefer,” and “strongly prefer” was estimated by using multinomial logistic regression. All percentages were adjusted for sex, age group, smoking status, income, education, children living in the home, wave of recruitment, and survey mode. Error bars indicate 95% CIs.
| Country | Would not prefer | Would prefer | Slightly prefer | Somewhat prefer | Strongly prefer |

| United States | 62.1 (56.8-67.1) | 37.9 (32.9-43.2) | 9.5 (6.6-13.6) | 11.2 (8.6-14.5) | 17.2 (13.0-22.4) |
