there are a number of conflicting statistics, and so it would be nice to know where their states are coming from.
For example Lifesource is in Northern Illinois outside of Chicago, and so their numbers might reflect rural farm country.

Of the 389 340 blood donations reported by donors aged 16 to 69 years (98.7% of all donations), the collections were from white (77.7%), African American (16.3%), Hispanic (2.3%), Asian (2.2%), and other (1.6%) donors. Forty- to 49-year-olds (26.8%) donated the highest percentage of units. The blood donor rates were 11 per 1000 population for whites, 6 per 1000 for African Americans and 3 per 1000 population for Hispanics. The blood donation rates were 77 donations per 1000 population for whites, 22 per 1000 population for African Americans and 10 per 1000 population for Hispanics.

It's the only one I found in a quick search that gave me donation rates on a per thousand basis. those should/could more or less hold up for other areas. And do the math to figure out how many people of which group live in a geographic zone.
