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 33 percent prediction interval was selected because the Healthy People 2030 Workgroup Subject Matter Experts expected that adoption of Tobacco 21 laws will increase substantially.

Methodology

Methodology notes

The minimum age of tobacco products refers to cigarette sales and e-cigarette sales in the STATE System and must be at least 21 years of age for both in order to meet the objective.

1. Because Healthy People 2030 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.
