About the National Data


Baseline: 86.5 percent of homes had adults aged 18 years and over who reported that smoking was not allowed in their home in 2014-15

Target: 92.9 percent

Number of homes in which all persons aged 18 years and over report that no smoking is allowed in their home.
Number of homes with at least 1 person aged 18 years and over.
Target-setting method


Target-setting method details
Linear trend fitted using ordinary least squares and a projection at the 75 percent prediction interval.
Target-setting method justification
Trend data were evaluated for this objective. Using historical data points, a trend line was fitted using ordinary least squares, and the trend was projected into the next decade. This method was used because three or more comparable data points were available, the projected value was within the range of possible values, and a projection at the 75 percent prediction interval was selected because as more states and communities adopt smoke-free laws and as more adults quit using tobacco, it was expected that voluntary smoke-free home rules will increase across the country.


Comparable HP2020 objective
Retained, which includes core objectives that are continuing from HP2020 with no change in measurement.



Because HP2030 objectives have a desired direction (e.g., increase or decrease), the confidence level of a one-sided prediction interval can be used as an indication of how likely a target will be to achieve based on the historical data and fitted trend.
