“…Several studies have attempted to develop population‐based approaches for monitoring NC over the past few years. In this manuscript, NC population‐based approaches are defined as a set of existing indicators or a composite index methodology that uses secondary data to measure, characterize, classify, and evaluate NC environment(s) for ECD (Buccini, Coelho, et al, 2021 ; Köhler, 2016 ; UNICEF & Countdown to 2030, 2020 ). The Countdown to 2030 early childhood country profile, the State of Babies in the United States, and the Early Childhood Friendly Municipal Index (IMAPI) in Brazil are examples of initiatives that measure NC at the countries, state, and municipal level, respectively (Buccini, Coelho, et al, 2021 ; Buccini, Pedroso, et al, 2021 ; Keating, Cole, & Schaffner, 2020 ; UNICEF & Countdown to 2030, 2020 ).…”
