This indicator measures the proportion of children of primary school age who are not participating in formal education, highlighting a critical gap in access to fundamental learning opportunities. These children, often missed by educational systems, face barriers that may include poverty, geographical challenges, cultural factors, or systemic inequities. The absence of schooling not only undermines their skill development and future economic prospects but also contributes to broader societal issues, such as increased rates of child labor and diminished lifelong opportunities. Understanding this metric is vital for policymakers and educators to implement targeted interventions aimed at improving educational access and developing inclusive programs that ensure every child has the chance to succeed academically.
