2 Salary Survey Trends 2015–2016 combining US and Canadian data. Initial diagnostics showed that some of the job categories had too few cases. These categories have been aggregated into the same groupings as in prior years. Race and Ethnicity There were 1,328 minority professional staff reported in 99 US ARL university libraries, including law and medical libraries.2 Note that the data for minority professionals comes only from the US ARL university libraries following the Equal Employment Opportunity Commission (EEOC) definitions. Currently, 14.9% 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% are directors (11 out of 110), 7.8% are associate directors (25 out of 320), 9% are assistant directors (12 out of 133) and 9.3% (34 out of 364) 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 85.1%, Asian/Pacific Islander 6.9%, Black 4.7%, Hispanic 2.9%, and American Indian/Alaskan Native 0.4%. Figure 1: Race/Ethnicity of Professional Staff in US ARL University Libraries, FY 2015–2016 Caucasian/Other 85.1% American Indian or Native Alaskan 0.4% Asian or Pacific Islander 6.8% Hispanic 3.0% Black 4.7% Minority professional staff in US ARL university libraries continue 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 Salary Survey data collection. Minorities are underrepresented by approximately 35% in the East South Central region and by almost 33% 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. 2 Some US institutions offer their librarians the option of not reporting race and ethnicity others forbid the tracking of racial and ethnic classification altogether.
