LA Los Angeles County, O Orange County, R Riverside County, SB San Bernardino County, SD San Diego County. Annual suicide rates were calculated from monthly county-level data, which exclude a small percentage of monthly counts suppressed due to small cell sizes in Orange, Riverside and San Bernardino Counties. Annual average temperature was calculated as the mean of all monthly average temperature values
