i Methodology: From December 11-17, 2020, FM3 completed 881 online and telephone (landline and wireless) interviews
with Californians vulnerable to COVID-19. To qualify for the survey, respondents had to have a household income under
$50,000, be a person of color, or be a Spanish-speaker. The survey included oversamples among African American Californians
and in the Central Valley. The survey was conducted in English and in Spanish. The margin of sampling error for the study is
+/-3.5% at the 95% confidence level; margins of error for population subgroups within the sample will be higher. Due to
rounding, not all totals will sum to 100%.
