    "The unit is the tract cluster. CDC publishes one rate for each group of neighboring tracts, and tracts inherit it. Tenths hold equal numbers of residents among the {fact:cook_cov} of Cook County residents who live in clusters with a rate in every year from 2022 to 2024. Clusters with zero recorded deaths hold {fact:cook_zero} of those residents and fill the lowest two tenths and part of the third, ordered among themselves at random with the book's fixed seed, so the first three tenths differ only in who lives there.",
