The internet’s anonymity and ease of publishing have allowed new voices to enter into debates over contentious issues. Yet in an era of polarized news choices, alternative facts and concern over “fake news,” it is not always clear which sources play the largest role in the debate. To help answer this question, the Center examined the information sources posted on Twitter about immigration during the first month of the Trump administration.

This study examined the most frequently appearing sites out of those linked to in all tweets about immigration during this time period. There were 1,030 different sites linked to in at least 750 tweets, which became the threshold for consideration in this study. These sites are organized into 14 mutually exclusive specific groupings and three broad categories: News Organizations, Other Information Providers and Other Sites.5

Most striking, sites in the News Organizations category – those that show evidence of publishing original reporting, such as interviews, eyewitness accounts or references to source documents in their top five most linked-to articles or the top five articles on their homepage – accounted for the largest proportion of these 1,030 sites (42%). And the legacy news organizations grouping accounted for twice as many sites as the digital-native news organizations grouping: 28% of all sites in this study compared with 14%, respectively. Almost three-in-ten are included in the Other Information Providers category (29%), predominantly the digital-native commentary/blogs (12%) and nonprofit/advocacy organizations (9%) groupings. A final 29% fell into the Other Sites category, including links to sites that no longer exist as well as consumer product entities, spam or other types of sites.

Below are the descriptions of each broad category and specific grouping.

News Organizations: 42%

Roughly four-in-ten of all sites (42%) fell into the News Organizations category. Sites in this category all show evidence of original reporting (such as interviews, eyewitness accounts or referrals to source documents) in the top five most linked-to articles on Twitter during this time period and the top five articles on their homepage when coding. Two groupings make up this category:

28% Legacy news organizations: Any news organization that was not “born on the web,” including print newspapers and television and radio broadcasting organizations. These news organizations include outlets like The New York Times, CNN and Fox News.
14% Digital-native news organizations: Any news organization that was “born on the web,” meaning their inaugural content was published online (even if they later also published broadcast or print content), and that publishes news about current events. This grouping includes politically focused news sites like Breitbart, Politico and ThinkProgress, as well as more general-interest news sites like The Huffington Post (now HuffPost) and Yahoo News.

Other Information Providers: 29%

Almost three-in-ten (29%) sites were in the Other Information Providers category, which includes sites focused on current events or public affairs information. It contains five groupings:

12% Digital-native commentary/blog sites: Sites that produce original content but do not show any evidence of original reporting in the top five most linked-to articles on Twitter during this time period and the top five articles on their homepage when coding. This grouping includes sites like Truthfeed, The American First and Zero Hedge.
9% Nonprofit/advocacy sites: Includes research organizations such as Cato Institute, broad advocacy organizations like the American Civil Liberties Union (ACLU) and immigration-focused organizations like America’s Voice.

Other Sites: 29%

7% Consumer products and internet services sites: Includes online shopping sites such as, internet services like, and file sharing sites like It also includes some companies that became part of the discussion about immigration like 84 Lumber, whose Super Bowl ad was perceived to be about immigration policy.
