12 · ARL Annual Salary Survey 2014–2015 Currently, 14.8% of the professional staff in US ARL university libraries (including law and medical libraries) belong to one of the four non-Caucasian categories for which ARL keeps records. The percentage of minorities in managerial or leadership positions in ARL academic libraries is far lower: 10.7% are directors (12 out of 112), 6.2% are associate directors (20 out of 323), 7.0% are assistant directors (11 out of 157) and 8.7% (33 out of 379) are the head of a branch library (see Table 31). Graph 1, below, depicts the overall racial/ethnic distribution of professional staff in US ARL university libraries: Caucasian/Other 85.2%, Asian/Pacific Islander 6.8%, Black 4.6%, Hispanic 3.0%, and American Indian/Alaskan Native 0.4%. Figure 1: Race/Ethnicity of Professional Staff in US ARL University Libraries, FY 2014–2015 Caucasian/Other 85.2% American Indian or Native Alaskan 0.4% Asian or Pacific Islander 6.8% Hispanic 3.0% Black 4.6% Minority professional staff in US ARL university libraries continues to be disproportionately distributed across the country. Using Figure 2, we can compare the number of minority staff with other staff, region by region. These patterns of distribution have been relatively stable for the entire history of ARL’s data-collection experience. Minorities are underrepresented by almost 37% in the West North Central region and by 34% in the New England region (see Table 27 for a definition of the regions). Proportionately to other regions, there are more minorities in the Pacific, Middle Atlantic, and South Atlantic regions.
