PRRI 2018 California Workers Survey




Jones, R. P., Cox, D., Griffin, R., Najle, M. B., Fisch-Friedman, M., & Vandermaas-Peeler, A. (2021, October 26). PRRI 2018 California Workers Survey.


The PRRI 2018 California Workers Survey includes a variety of worker and labor-related issues, including their opinion on the state of affairs in respondents' communities, in California, and nationally. The survey also examines respondents' economic status including their goals, financial hardships, job status, level of debts, and access to certain banking accounts and retirement plans. Additionally, the survey includes an oversample of those working and struggling with poverty-bringing the total of this group to more than 1,000-and provides insights into their unique experiences, challenges, and aspirations. For the purposes of this study, respondents are classified as 'working and struggling with poverty' if they meet two criteria: 1) They are currently employed either full or part-time or are unemployed but still seeking employment; and 2) They live in households that have an adjusted income that is 250 percent or less than the U.S. Census Bureau's Supplemental Poverty Measure, adapted for regional location in California.

The ARDA has added four additional variables to the original data set to enhance the users' experience on our site.

Data File

Cases: 3318
Variables: 177
Weight Variable: WEIGHT

To reduce the effects of any non-response bias, a post-stratification adjustment was applied based on demographic distributions from the most recent Current Population Survey (CPS). The post-stratification weight rebalanced the sample based on the following benchmarks: age, race and ethnicity, gender, Census division, metro area, education, and income. The sample weighting was accomplished using an iterative proportional fitting (IFP) process that simultaneously balances the distributions of all variables. Weights were trimmed to prevent individual interviews from having too much influence on the final results. The final weight was computed to ensure that the demographic characteristics of the sample closely approximate the demographic characteristics of the target population.

PRRI 2018 California Workers Survey

Funded By

The PRRI 2018 California Workers Survey was supported by a grant from the James Irvine Foundation.

Collection Procedures

The PRRI 2018 California Workers Survey was conducted by PRRI among a random sample of 3,194 adults (age 18 and up) living in California who are part of GfK's Knowledge Panel. Additionally, the survey includes 124 Californians who are working and struggling with poverty from NORC's AmeriSpeak panel. This brought the total sample of Californians to 3,318 and the total sample of those working and struggling with poverty to 1,068. Interviews were conducted online in both English and Spanish between May 18 and June 11, 2018. The survey is supported by a grant from the James Irvine Foundation.

Sampling Procedures

Respondents are recruited to the KnowledgePanel using an addressed-based sampling methodology from the Delivery Sequence File of the USPS-a database with full coverage of all delivery addresses in the U.S. As such, it covers all households regardless of their phone status, providing a representative online sample. Unlike opt-in panels, households are not permitted to 'self-select' into the panel and are generally limited to how many surveys they can take within a given time period.

The initial sample drawn from the KnowledgePanel was adjusted using pre-stratification weights so that it approximates the adult U.S. population defined by the latest Current Population Survey. Next, a probability proportional to size (PPS) sampling scheme was used to select a representative sample. Once assigned to the survey, panel participants received an email notification on May 18 to complete the survey. Additional email reminders were sent out on May 21, May 26, and May 29.
