Math is math...we know the number of people who were shot...we know the demographic breakdown of the people who were shot...we know the population sizes of the various demographic.
(non-Hispanic) whites comprise a roughly five times greater share of the U.S. population (62% vs. 13%).
A total of 1,388 people were killed by police in 2015, 318 (23%) of them black, and 560 (40%) of them white. So roughly 23 percent of those killed by any police interaction in 2015 were black and just over 40 percent were white. According to those statistics (adjusted for racial demographics), black people had a 2.7 higher likelihood of being killed by police than whites.
When adjusting for population size...
318/13 if we adjust that ratio to match the white population size X/62... X becomes roughly 1,516.
So, when comparing 1516 to 560... we have 2.707 time higher likelihood...which matches the number reported in the linked stats I posted before.
I've seen numerous articles before that attempt to refute that stat, and they always have to incorporate a bunch of unrelated (or barely related) statistics to try get those numbers down to where they can try to prove their point.
They'll try to change the stat perspective and make it about "x number of interactions with police", they'll try to incorporate "urban environment vs. rural".
No matter which way a person tries to creatively present the data, at the end of the day, the raw numbers are: Whites make up 62% of the population, and only 40% of the people killed by police, as where Blacks make up only 13% of the population, but 23% of the people shot by police.
If you're trying make a case for the people being killed by police attributed to something other than bias, then that's a different conversation. However, in terms of the percentages of people being killed by police (for whatever reason), the data is crystal clear on that one.
