About the Index

The Polarization Index (PI) is the first data science-based measure of the overall degree of polarization in America, as well as the level of polarization across ten key issues. 

It reveals which side of the political spectrum is most engaged with an issue, how far apart both sides are, and points to how much unreliable information is being shared. 

Current Issues

The nature of polarization can shift rapidly due to an event or a policy debate. Hot-button issues examined in this PI report have been chosen through survey data and continued prevalence in news cycles over the past year.

Immigration
Racial Equity
Voting Integrity
Abortion
Healthcare Reform
Policing Policy
Gun Legislation
COVID-19 Vaccines
Climate Change
Minimum Wage

Developed in collaboration with PR firm Golin and narrative intelligence company Zignal Labs, the Polarization Index (PI) from USC Annenberg leverages Zignal’s real-time natural language processing capabilities to mathematically calculate the overall national degree of discord, as well as tracks political bias and reliability across 10 key issues, determined in part by a USC survey of professional communicators.
