In 2015 and 2016, 126 people were killed in Baltimore's Western District. Eighty-six were black men age 18 to 34. (By comparison, 64 people were killed in the two preceding years.) Based on a total population of 38,000, there are approximately 4,500 black men aged 18 to 34 in the Western District. So the annual homicide rate for 18-to-34-year-old men in the Western District over the past two-year is 955 per 100,000. (The national homicide rate is now about 6 per 100,000; Baltimore's is 50.)
What does a murder rate of 955 mean? Well, here's a survival function:
1 - (1 - r)^xThis means that if homicide levels don't drop, a 17-year-old man in the Western District will have a 17 percent chance of being murdered before he reaches the age of 34. The numbers before 2015 weren’t great. Actually, they were pretty terrible; but they were a hell of lot better.
r is the death rate and x is number of years. The death rate is 1 in 105 or .009555. The number of years from 18 to 34 is 17. So 1 - (1-.009555)^17 =0.1747.
One-in-five men murdered?! I don't know what else to say.
