2020 was a record year, not least because of the enormous influx of Covid-related news. By our calculations, as many as 500 articles were published by major local and national news outlets every day over the course of the year. That left a huge range of choice for readers seeking quality, well-researched journalism.

The Factual’s credibility algorithm analyzes 10,000 articles a day from across the U.S. media ecosystem, assessing the credibility of each article based on linked evidence and sources, writing tone, author expertise, and publisher history. To learn more, watch this video or visit our “How It Works” page.

From this data collection, we accrued a dataset of nearly 180,000 articles published about Covid-19 in 2020. Beyond looking at broader media trends and coverage of the pandemic, it allows us to highlight the very best outlets from the left, right, and center, based on clear, quantifiable metrics.

Here’s our top 10 nonpartisan news sources for Covid-19 coverage.

Some things to remember:

  • These scores are not like percentage grades — they reflect our algorithm’s level of confidence that a piece of content is credible. Anything over 75% is highly likely to be credible.
  • Our dataset does not necessarily include all articles published by each outlet during the time period. However, in many cases we are confident our data is at the very least a representative sample.
  • The political bias of each publisher is derived from classifications from AllSides and Media Bias Fact Check. Note that the political bias of individual articles may vary from any publisher.
