Ethnicity reporting practices for empirical research in three autism-related journals.

Sawyer et al. (2014) read every research paper in three top autism journals for one year. They counted how many studies told readers the ethnicity of the participants.

Most autism studies left ethnicity out of the participant table. The authors warned that this gap hides who is really being studied.

Lovelace et al. (2022) extends the same worry. They looked back 77 years and found only three papers that focused on Black autistic women and girls. Together the two reviews show the field first omits ethnicity, then also omits whole minority groups.

Anonymous (2024) and Fradet et al. (2025) add a second layer: autistic adults want research led by autistic people and rooted in real-life context. So the problem is not just missing labels; it is missing voices.

Milton (2014) closes the loop. That paper argues that without autistic co-researchers, even perfect ethnicity tables still treat people as data points, not partners.

If you publish or review autism studies, add one column: ethnicity. One extra line in the participant table lets future meta-analyses spot disparities and design fairer interventions. It takes five minutes and costs nothing.
