According to the UNICEF report "Prospects for Children in 2025," what is the estimated number of children living in conflict zones as of 2023?

The UNICEF report "Prospects for Children in 2025" highlights the severe impact of global conflicts on children, noting that over 473 million children, or more than one in six globally, lived in conflict zones in 2023. This represents a significant increase from the 1990s, where the proportion of children affected by conflict was around 10%, rising to 19% recently. These children are exposed to numerous risks including displacement, starvation, disease, and psychological trauma, underscoring the urgent need for enhanced protective measures and support systems for young populations in conflict-affected areas.
