Diversity, equity, and inclusion (DEI) are essential in corporate activities, particularly for achieving sustainable development goals. Diversity marketing in advertising appeals to consumers, but measuring and embracing diversity remains unclear. This study proposed new diversity indices and conducted a survey to explores university students' acceptance of diversity in an advertisement for a hypothetical educational institution, analyzing the distribution and factors related to this acceptance. Using the new index and statistical methods such as linear regression and causal discovery, we found a positive correlation between the index and media usage on the web or Instagram. These findings offer insights for promoting inclusivity, diversity education, and targeted communication strategies.
