About the National Data
Data Source: National Health Interview Survey (NHIS), CDC/NCHS
Baseline: 56.0 percent of adult smokers aged 18 years and over attempted to stop smoking for 1 day or more in the past 12 months or quit during the past year in 2020
Target: 65.7 percent
Percentage point improvement
Adults are classified as current smokers if they report currently smoking cigarettes "everyday" or "some days". The methodology counts both successful (currently abstinent less than one year) and failed cessation attempts in the last 12 months. This indicator uses age-adjustment groups: 18-24, 25-34, 35-44, 45-64, 65+.
In 2022, due to the 2019 NHIS redesign, the baseline was revised from 56.0% in 2018 to 56.0% in 2020.
The target remained 65.7% using the original target setting method of percentage point improvement.
1. Effect size h=0.2 was chosen to correspond with 20% improvement from a baseline of 50%.
