We hope this API is useful to different research groups.
If you use the API and would like to cite it, the following represents a proper citation of the API itself:

When referring to the survey in text, we prefer the following formats:
- Long form (such as in an introduction or methods description): “The University of Maryland Social Data Science Center Global COVID-19 Trends and Impact Survey, in partnership with Facebook”.
- Short form (used after the long form has been introduced): “The Global COVID-19 Trends and Impact Survey”
- Acronym form: “UMD Global CTIS”
Prior to July 2021, the survey was known as the COVID-19 World Symptom Survey Data API, and some older documentation and publication may still refer to this name. We prefer that new publications and materials refer to the new name.
