Definitions

Patient profile: One panel member profiled for one condition. A person living with two conditions is counted once for each, so profile totals are higher than the number of people.
Therapeutic area: A group of related conditions, such as oncology or cardiovascular.

About this data

Figures come from Global Vox Populi's proprietary panel coverage records and show panel membership as of October 2026. They describe the people available on the Global Vox Populi panel, not the total population of patient profiles in each country. Countries without current panel coverage are not listed. Totals across different Global Vox Populi panels should not be added together, because some people belong to more than one panel.

For live panel coverage and feasibility for a specific study, see the Patient panel explorer or use the survey feasibility calculator.
