Understand the impact of data disaggregation.

Disaggregation means breaking down large data categories into more specific subcategories.

“Data disaggregation” refers to the collection, reporting, and analysis of information on specific subgroups by race, ethnicity, and other characteristics. When data are disaggregated, researchers are better able to analyze differences between groups, as well as the relationship between multiple variables, such as race and age.

We are the Data Disaggregation Action Network (D-DAN).

The Data Disaggregation Action Network (D-DAN) works to advance and implement federal and state policies as they relate to data disaggregation by race and ethnicity through the engagement and empowerment of communities. The D-DAN state and national advocacy infrastructure helps communities achieve equity by engaging stakeholders, policymakers, and communities on the need for disaggregated data and by collaborating to improve data quality and accessibility.
