Citing

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:

Junchuan Fan, Yao Li, Kathleen Stewart, Anil R. Kommareddy, Andres Garcia, Joe O’Brien, Adrianne Bradford, Xiaoyi Deng, Samantha Chiu, Frauke Kreuter, Neta Barkay, Alyssa Bilinski, Brian Kim, Tal Galili, Daniel Haimovich, Sarah LaRocca, Stanley Presser, Katherine Morris, Joshua A Salomon, Elizabeth A. Stuart, Ryan Tibshirani, Tali Alterman Barash, Curtiss Cobb, Andi Gros, Ahmed Isa, Alex Kaess, Faisal Karim, Roee Eliat, Ofir Eretz Kedosha, Shelly Matskel, Roee Melamed, Amey Patankar, Irit Rutenberg, Tal Salmona, David Vannette (2020). The University of Maryland Social Data Science Center Global COVID-19 Trends and Impact Survey, in partnership with Facebook. https://covidmap.umd.edu/api.html

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.
