According to Census Bureau (2019)[1], this is the racial/ethnic makeup of the US:

    White                                       60.4%
    Hispanic and Latino Americans (of any race) 18.3%
    Black or African American                   13.4%
    Asian                                       5.9%
    Native Americans and Alaska Natives         1.3%
    Native Hawaiians and Other Pacific Islander 0.2%
    Two or more races 2.7%

Below is the normalized 2019 CS Ph.D. count for what you'd expect if the US was 100% of each respective race/ethnicity:

    White                          608
    Hispanic...                    115
    Black or African/American      97
    Asian                          2,560
    Native Americans/Alaska Native 153
    Native Hawaiian/Pac Islander   500
