Weekly / November 26, 2021 / 70(47);1652
* 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.pdf
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.
