Final answer:
White Americans currently represent the majority of the public health workforce in the U.S., but racial and ethnic diversity is increasing, and this majority is projected to decrease over time as the Hispanic population grows and women advance in their careers.
Step-by-step explanation:
The question asks which race/ethnicity currently represents the majority of the public health workforce in the United States. As of the information provided, white Americans were the dominant demographic group in the U.S. overall and, by extension, can be inferred to be so in the public health workforce.
However, it is important to note that racial and ethnic diversity in the workforce is increasing, and the share of white Americans is projected to decrease to 69% by 2060.
The Hispanic or Latino population, in particular, is expected to rise significantly. Workforce diversity is further enriched as women gain more prominent positions through promotions within their organizations.
As the U.S. population becomes more diverse, these changes are reflected in the workforce composition. Figure 14.16 illustrates the projected changes in America's racial and ethnic diversity, indicating a continued trend towards a more ethnically varied population, which could affect the makeup of the public health workforce in the future.
