The Central Valley Business Times reported on a recent survey that used data collected by Abt SRBI, which showed the most important environmental issue facing California is water supply and drought:
“Live landline and cell phone interviews were conducted by Abt SRBI Inc., in English and Spanish, according to respondents’ preferences. Accent on Languages Inc., translated new survey questions into Spanish, with assistance from Renatta DeFever.
Abt SRBI uses the U.S. Census Bureau’s 2010-2014 American Community Survey’s Public Use Microdata Series for California (with regional coding information from the University of Minnesota’s Integrated Public Use Microdata Series for California) to compare certain demographic characteristics of the survey sample — region, age, gender, race/ethnicity, and education — with the characteristics of California’s adult population. The survey sample was closely comparable to the ACS figures. To estimate landline and cell phone service in California, Abt SRBI used 2014 state-level estimates released by the National Center for Health Statistics — which used data from the National Health Interview Survey (NHIS) and the ACS — and 2015 estimates for the West Census Region in the latest NHIS report. The estimates for California were then compared against landline and cell phone service reported in this survey. PPIC says it also used voter registration data from the California Secretary of State to compare the party registration of registered voters in our sample to party registration statewide. The landline and cell phone samples were then integrated using a frame integration weight, while sample balancing adjusted for differences across regional, age, gender, race/ethnicity, education, telephone service, and party registration groups.”
