Relative age effects in women’s and girls’ cricket

Background: Relative age effects (RAEs) refer to the overrepresentation of athletes born earlier in a selection year and may influence talent identification in sport. While RAEs are well-documented in male cricket, limited research exists in the female game. Purpose: To examine the prevalence of RAEs across the England and Wales Cricket Board (ECB) women’s and girls’ national talent pathway, from youth to senior levels. Research Design: A cross-sectional design comparing observed and expected birthdate distributions. Study Sample: Data were collected for 289 players from six cohorts: Regional Festivals (n = 108), School Games (n = 48), England U19 World Cup Squad (n = 15), and senior national squads—T20 (n = 47), ODI (n = 41), and Test (n = 30). Data Collection and/or Analysis: Players’ birthdates were categorised into quartiles based on the UK academic year. Chi-square tests and odds ratios (95% CIs) were used to assess RAEs by cohort and skill set (batters, bowlers). Transitions from youth to senior levels were also examined. Results: Significant RAEs were identified in all youth cohorts, with relatively older players overrepresented. In contrast, senior cohorts showed a reversal effect, with relatively younger players more prevalent, particularly among those who played more matches. These patterns were evident across both batters and bowlers. Conclusions: RAEs are present in the ECB women’s and girls’ talent pathway, suggesting selection biases that may hinder long-term development. Stakeholders should implement strategies to create a more equitable pathway and support all players in realising their potential.
