Final answer:
The assertion that trainers face a more diverse population than ever before is true, reflecting the demographic changes and increased workforce diversity in the U.S.
Step-by-step explanation:
The statement that the population for trainers is now more diverse than ever in regard to who they may be training is true. The job market has undergone a significant transformation, with requirements for more education and training than in the past. The workforce includes a larger percentage of women and minority groups, reflecting wide-ranging changes in the U.S. population demographics. As the white American population, which comprised 78% of the population in 2012, is projected to decrease to 69% by 2060, racial and ethnic diversity is evidently on the rise. Additionally, the Hispanic population in the U.S. is predicted to increase substantially. The surge in workforce diversity is demonstrated by women who entered the workforce in the 1970s and 1980s now advancing in their careers. These developments indicate that trainers today are indeed working with a more diverse group than ever before.
