Self‐report = Self‐reported race and ethnicity collected through the permission portal from motherss who enrolled a child in Early Check. ACS estimate = Race and ethnicity based on census tract–level proportions among women of reproductive age who reported giving birth in the past 12 months on the ACS, using 5‐year estimates for the years 2013–2017. NBS record = Race and ethnicity recorded on the NBS bloodspot form and reported in NCSLPH data. 2018 NCDHHS = NC resident birth for female mothers ages 15–44 by race and ethnicity of the mother, drawn from 2018 NCDHHS fertility statistics. Significance levels reported in the Self‐report, ACS estimate, and NBS record columns are from two‐sample tests of proportions comparing proportions by race and ethnicity in the 2018 NCDHHS percentage column.

ACS, American Community Survey; EC, Early Check; NBS, newborn screening; NC, North Carolina; NCDHHS, North Carolina Department of Health and Human Services; NCSLPH, NC State Laboratory of Public Health.

^{^a}

There were 1,093 (49.6%) NC residents who enrolled in Early Check in this time period and did not provide race or ethnicity information when they signed up. These missing cases were excluded from the data reported in the self‐report columns.

^{^b}

There were 91 (4.0%) NC residents who enrolled in Early Check in this time period and could not be matched to the relevant ACS race and ethnicity data. These missing cases were excluded from the data reported in the estimate columns.

^{^c}

There were 8,285 (15.0%) NC residents who gave birth during this time period and did not have race or ethnicity information recorded when the bloodspot was collected. These missing cases were excluded from the data reported in the NBS record column.

^{^d}

There were 2,216 (4.0%) NC residents who gave birth during this time period and could not be matched to the relevant ACS race and ethnicity data. These missing cases were excluded from the data reported in the estimate column.
