To examine relationships between violence, age (0-74 years), and deprivation, and to explore in which communities, age groups, and gender the potential for transmission of violent tendencies between individuals is greatest. ⋯ Analyses identify four lifetime periods for violence: up to 10 years (prepubescent), 11-20 years (adolescence), 21-45 years (younger adults), and over 45 years (older adults). While violence is most common in adolescence, its concentration in poorer areas during prepubescence and in younger adulthood (parenting age) suggests that poorer children are exposed to much more aggressive communities. This is likely to contribute to the disproportionate escalation in violence they experience during adolescence. Effective interventions to prevent such escalations are available and need to be implemented particularly in poor communities.
