From FiveThirtyEight:
“For decades, research on discrimination would just look at observational data — on men and women, blacks and whites,” David Neumark, an economist at the University of California at Irvine and an author of one of the new age-discrimination studies, said in an interview. The study by Neumark and his co-authors is by far the largest known résumé correspondence study. They sent out 40,000 résumés, randomizing the applicants’ names and year of graduation to signal their gender and age. Résumés with women’s names were submitted for roughly two types of positions: administrative (secretaries and assistants, office and file clerks, receptionists) and sales (retail workers and cashiers). Résumés with men’s names also went out for jobs in retail sales, as well as for janitorial and security guard positions. Across all occupations, Neumark and his team found lower callback rates for women ages 64 to 66 (12 percent) than for women ages 29 to 31 (19 percent). Older men, however, didn’t seem to have lower callback rates than younger ones — with one exception. Janitorial jobs seemed to discriminate against older men; Neumark speculated that a perceived reduction in physical stamina could be one explanation.
