Challenges in measuring the internet for the public interest

The goal of this article is to offer framing for conversations about the role of measurement in informing public policy about the Internet. We review different stakeholders' approaches to measurements and associated challenges, including the activities of U.S. government agencies. We show how taxonomies of existing harms can facilitate the search for clarity along the fraught path from identifying to measuring harms. Looking forward, we identify barriers to advancing our empirical grounding of Internet infrastructure to inform policy, societal challenges that create pressure to overcome these barriers, and steps that could facilitate measurement to support policymaking.
