California Public Opinion Polls

Field Polls

The Field Poll, or the California Poll, was established in 1947 by Mervin Field and operated continuously as an independent, non-partisan, media-sponsored public opinion news service through 2016, with a focus on California voters.  These polls cover a wide range of political and social topics, including:

  • approval of important national and statewide political figures,

  • reactions to significant political events and hot button issues,

  • opinions on California ballot propositions,

  • voter awareness,

  • understanding and predispositions of major campaign issues,

  • party affiliation, and

  • demographic characteristics.

IGS Polls

Since 2015, the UC Berkeley Institute of Governmental Studies (IGS) has continued the mission of the Field Poll.  The Berkeley IGS Poll is a periodic survey of California public opinion on important matters of politics, public policy, and public issues. The poll, which is disseminated widely, seeks to provide a broad measure of contemporary public opinion, and to generate data for subsequent scholarly analysis. The D-Lab makes the IGS Poll data available for download or online analysis. The IGS Poll reports can be downloaded from eScholarship
