In school racial/ethnic diversity research, mathematical diversity indices operationalizing dual-concept diversity are the dominant measure, with Simpson's D the most widely applied, and most studies assess static diversity at a single timepoint¶

Subclaims¶

q3 i? Mathematical diversity indices consistent with dual-concept diversity were used in 85 of the reviewed studies, and the Simpson's D index was the most widely applied (n = 75). → Chan 2023 q3 i? The vast majority of reviewed studies employed a static concept of diversity at a particular timepoint; only five studies incorporated the dynamic concept. → Chan 2023 (2)

q3 · i? · review · r3

Systematic review (PRISMA, 1970–2023; 114 included studies) coding diversity measures. The review reports that "Mathematical indices of diversity are a prevalent measure in the existing school racial/ethnic diversity literature (n = 85)", with Simpson's D the most widely applied (n = 75).

"Mathematical indices of diversity are a prevalent measure in the existing school racial/ethnic diversity literature (n = 85)."

q3 · i? · review · r2

Coding of social spaces across the 114 reviewed studies found most used static diversity; "five studies incorporated the dynamic concept by taking the average of diversity index values across contexts or timepoints for each participant."

"Among the reviewed studies, the vast majority of them employed static concept to capture school racial/ethnic diversity of a context at a particular timepoint"

Discussion¶

Related Claims¶

• The range and value of diversity indices are constrained by the number of racial/ethnic groups included, complicating comparisons across studies — related
• Simpson's D index is insensitive to small groups, so contexts with vastly different racial/ethnic compositions can receive nearly equivalent index values — related
• A substantial minority of school diversity studies operationalize normic diversity via minority representation, while representative diversity is rarely measured — related
• Ingroup representation and racial/ethnic diversity are distinct constructs that are often conflated in school diversity research — related
