    "Large counties are the counties that CDC WONDER names individually: those with {fact:wonder_threshold} residents or more. WONDER pools the births of every smaller county in a state into one row, so smaller counties are not in these data. Of the {fact:n_named} large counties named in every year from 2018 to 2024, California ({fact:n_ca}) and {fact:n_dropped} counties with a withheld smoking count are left out, which leaves {fact:n_complete}.",
    "A county's smoking share is the births to mothers who reported smoking over the births with a known answer, Yes plus No. Births with an Unknown or Not Stated answer are left out of the denominator.",
    "A county's interval is a Wilson score interval on its births, which treats births as independent; it describes the county's own count and not the spread across counties.",
    "Connecticut is shown as its eight legacy counties, the coding of the source. Alaska is drawn. Puerto Rico is not in these data and is not drawn.",
    "California's counties are gray because the source states that California does not routinely collect the item; its reported share for 2018 is {fact:ca_share_2018}, against {fact:share_all_2018} in the counties kept, and lower than the share in any state kept."
