Mapping solitary confinement

Dr Sharon Shalev, Centre for Criminology, University of Oxford


This project aims to draw a picture of how, when, why and for how long people can be placed in solitary confinement (also known as ‘segregation’, ‘separation’ or ‘isolation’) in different countries, and what their daily life looks like. 

The project seeks to identify common patterns and good practice, and to help inform reform efforts.


The questionnaire covers many aspects of solitary confinement (defined as 22+ hours a day in cell). Some of the information detailed below will not be available - please include as much detail as possible, and web-links where available. Please also include images where available and PDFs of relevant reports. If you are only able to answer a few questions, that would be very welcome too. Once completed, this information will be analyzed, triangulated, and uploaded into a dedicated webpage. It will be updated regularly.


Please indicate yours and your organization’s name, sector, your role, and contact details. This information will remain confidential. Please indicate if you would like your contribution to be acknowledged in the published outcome. If you would like to share specific confidential information or concerns, please email me separately. 


Contributions appreciated by 15/12/2021, but late submissions welcome too as this database is a living instrument updated as information becomes available.  

An online version of this survey is available here:

Thank you very much for your contribution!
