A nonprofit and resource for researchers, academics, policy-makers, advocates, and those who have been directly impacted. This website is a collection of information on access to menstrual products and support for menstruation in federal and state prisons. All of the information is publicly accessible, linked to the source wherever possible, and dated. **A quick note that this issue exists in other facilities such as jails and immigration detention centers. Also, not every woman menstruates and not everyone who menstruates is a woman.**
