This page summarizes the data and documentation associated with the 2016 USC Dornsife / LA Times Presidential Election Daybreak Tracking Poll, (July 4 - November 7, 2016). It includes the poll's cumulative longitudinal data, UAS post-election data collections, and associated documentation, examples, and programs. To access these UAS data files, simply register as a UAS data user.

Answers to some questions about the outcome of the 2016 Daybreak poll are here. We recommend supplementing the original weighting of the 2016 Daybreak poll by adding a benchmark for the census urbanicity variable, and adding that variable to the weights. For more information please contact us.

Note: Basic demographics are included in all files. As with all UAS data sets, election data may be linked to variables from Other UAS surveys for further analysis if desired. Information on weighting the Daybreak poll is included in the Daybreak Poll Data Documentation and Codebook , and example weighting programs are available upon request.


Pre-election data consists of the 2012 vote and election panel consent survey, the Daybreak tracking poll cumulative files (original and final), and three stand-alone full-panel surveys. Please consult the Daybreak Poll Data Documentation and Codebook for more information on methodology and content of these files.
