The racial makeup of the city in 2010 was 32% black, 28.9% Hispanic/Latino, 31.7% non-Hispanic white, 5% Asian , and 3% from two or more races. (wiki).Though there are far more murders by blacks, they are killing each other, not whites, and the vast majority of those deaths have to do with drugs. Blacks tend to be poorer than whites, and less educated, therefore, as in any city around the world, the poor people are more involved in drugs. There is a logical reason behind the murder rate, one that is not raced based but more based in poverty and less opportunities and advantages.
All over the world and throughout history, the poor, the disadvantaged, the poorly educated have been more involved in crime. Because Chicago is a drug cartel distribution center, Chicgao is a violent city, the violence for the most part related to drugs.
