A better understanding of the relative age effect (RAE) in youth will increase the awareness of the need for reducing the bias of (de)selection. Thus, we investigated the RAE in youth female and male soccer and futsal players in Portugal, using nationwide data. Birthdates of 5,306 female and 126,285 male soccer players, and 2,437 female and 23,988 male futsal players (U7-U19), registered in Portugal during the season 2019-2020, and Portuguese National teams (from U15 to AA soccer teams and from U17 to AA futsal teams) were analyzed.
