Number codes like 13/50 are used by white supremacists to perpetuate a racist myth that black people are inherently prone to crime or violence. 13/50 is a code for the false claim that Black Americans commit 50% of violence crime despite making up 13% of the population. The percentages and the slogan often appear in similar numbers like 14% and 51%, respectively. Because they are coded, they can appear in memes that do not immediately appear to be hateful to those unfamiliar with them.
