Figure is a bar graph indicating percentage of U.S. births in 2020 to mothers who reported smoking cigarettes at any time during pregnancy, by urbanization level of county of residence, based on data from the National Vital Statistics System.

* Urbanization level is based on county of residence using the National Center for Health Statistics Urban-Rural Classification Scheme for Counties. http://www.cdc.gov/nchs/data/series/sr_02/sr02_166.pdfpdf icon

In 2020, 5.5% of all births were to women who reported smoking cigarettes at any time during pregnancy. This percentage was lowest in large central metropolitan areas (2.3%) and increased as the county of residence became less urbanized, reaching a high of 13.6% in the most rural (noncore) counties.
