We have a large African American, Asian community due to the UW.
Plus I go to school in the U-District
Seattle, and the Pacific Northwest at large, are known for being largely white compared to other major cities in the country.
As of the 2010 census, there were 3,439,809 people, 1,357,475 households, and 845,966 families residing within the MSA. The racial makeup of the MSA were as followed:[2][3]
White: 71.9% (Non-Hispanic White)
Black or African American: 5.6%
American Indian and Alaskan Native: 1.1%
Asian: 11.4% (2.3% Chinese, 2.0% Filipino, 1.6% Vietnamese, 1.5% Indian, 1.5% Korean, 0.8% Japanese, 0.5% Cambodian, 0.2% Laotian, 0.1% Thai, 0.1% Pakistani, 0.1% Indonesian)
Pacific Islander: 0.8% (0.3% Samoan, 0.2% Guamanian or Chamorro, 0.1% Native Hawaiian)
Two or more races: 5.3%
Some other race: 3.8%
Hispanic or Latino (of any race): 9.0% (6.4% Mexican, 0.5% Puerto Rican, 0.4% Spanish or Spaniard, 0.2% Salvadoran, 0.1% Guatemalan, 0.1% Peruvian)
The black and hispanic populations are not integrated within the larger white communities. For a city a population of 5.6% black is not large at all and neither is 9% Hispanic. As tech companies like Amazon et al continue to grow and expand within the city core more neighborhoods will experience the effects of gentrification and could see even fewer non-white residents as well.
Students are transient and do not influence much outside of the University District. Going to school with Indian and Chinese people does not automatically exclude you from being able to have racial bias either.
I'm not judging you and calling you tribal, but I think it's a misstep to say you're not because of the reasons you gave.
