Regional trends in mortality for infants aged 0–1 years, children aged 1–4 years, older children and young adolescents aged 5–14 years, and youth aged 15–24 years in 1990 and 2019 (A), and absolute numbers of deaths by age group (B)

Shaded areas represent 90% uncertainty intervals. Probability ₁q₀ is the probability of infants alive at birth dying before reaching age 1 year, probability ₁q₄ is the probability of children alive at age 1 year dying before reaching age 5 years, probability ₁₀q₅ is the probability of young people alive at age 5 years dying before reaching age 15 years, and probability ₁₀q₁₅ is the probability of youths aged 15 years dying before reaching age 25 years, all expressed per 1000 live births, children, or young people (depending on the age group considered). Definitions of regional classifications are in the appendix (p 164).
