Key facts about mothers smoking while pregnant
• From 1989 to 2006, the percentage of all births where mothers reported smoking during pregnancy decreased by about half, from 20 to 10 percent. Slower declines occurred from 2006 to 2016, when the rate hit 7 percent. However, caution is recommended in interpreting changes over time; before 2016, not all states had adopted a uniform way of collecting these data.
• In 2016, mothers reported smoking during pregnancy in 16 percent of births to American Indian or Alaska Native mothers, compared with 11 percent of births to non-Hispanic white mothers, 6 percent of births to black mothers, 2 percent of births to Hispanic mothers, and 1 percent of births to Asian or Pacific Islander mothers.
• In 2016, pregnant women (ages 20 and older) with a bachelor’s degree or higher (1 percent) were less likely to smoke than those who had some college or an associate’s degree, a high school diploma, or a ninth through twelfth grade education (8, 12, and 16 percent, respectively).
