Intro to the MAIHDA Approach for Estimating Intersectional Inequalities & Its Statistical Advantages

This seminar was recorded as part of the DSPI Trinity Term Seminar Series in May 2025. Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) is a recent multilevel regression modeling approach, rooted in intersectionality theory, for examining social inequalities across intersections of multiple social identities (e.g., gender, ethnicity, social class). The method was proposed in social epidemiology, but is increasingly applied in social science research. In this talk Professor Leckie gives an introduction to MAIHDA including an empirical example drawn from published education research. He uses this to motivate and present my own recent methodological research which explores the claim that MAIHDA’s predicted intersectional means are statistically superior to simple means from descriptive statistics and conventional regression models. Specifically, he discusses the bias, variance, and mean squared error properties of these competing predictions. The findings show that MAIHDA-based means outperform simple means. However, the relative advantage of each MAIHDA predictor depends on the nature of intersectional inequalities and intersection sizes. MAIHDA’s benefits are most pronounced when inequalities are subtle or when data on certain intersections, such as those for marginalized groups, are sparse—conditions common in practice, highlighting the practical significance of our findings.
