Sample sizes appearing in the NIS breastfeeding tables are slightly smaller than the numbers published in other NIS publications due to the fact that in the DNPAO breastfeeding analyses, the sample was limited to records with valid responses to the breastfeeding questions.

Counties and cities not sampled or with sample size <100 (AL-Jefferson County; AZ-Maricopa County; CA-Alameda County; CA-Fresno County; CA-San Bernardino County; CA-San Diego County; CO-Denver; FL-Duval County; GA-Fulton/DeKalb Counties; KS-Eastern KS; LA-Orleans Parish; MA-City of Boston; MI-City of Detroit; MO-St. Louis County/City; NJ-City of Newark; NM-Southern NM; NV-Clark County; OH-Cuyahoga County; OH-Franklin County; PA-Allegheny County; TN-Davidson County; TN-Shelby County; WA-King County; and WI-Milwaukee County) are not reported on in this table.
