Fig. 2: COVID-19 news media articles published over the timeframe of this study and by news outlet.

For each randomly sampled day (A) and each news outlet (B), the total number of individual news records is shown, based on Factiva database searches for articles related to COVID-19 public health and policy information (Methods). News articles are partitioned across the following categories: articles eligible for inclusion in our study (eligible), articles not focusing on the newspaper’s country of publication (location out of scope), articles that are not original news reporting or analysis (opinion/editorial/letters), and articles that include COVID-19-relevant search terms, but do not include any direct focus on COVID-19 public health or policy information (no direct focus). Estimated totals for these categories are calculated using (i) the total number of Factiva returns and (ii) the rates at which articles were assigned to these categories during the eligibility screening process for each outlet and randomly sampled day (SI Fig. S4). On the stacked bars, percentages of articles falling into each category are specified for each day (A) and news outlet (B).
