How the poll was conducted: The William C. Velásquez Institute conducted an exit poll to measure how Latinos voted during the November 1998 mid-term elections. The survey was administered by trained interviewers in both English and Spanish. WCVI pollsters interviewed 420 Latino voters in 33 California precincts. The sample was designed to cover 90% of all Latino voters in the state. Precincts from 5% to 100% of registered Latino Voters were included in the sample. The design is a stratified, two stage, probability-based sample. Precincts were included in the universe if they met minimum levels with respect to number and percentage of Latino voters. Precincts were then stratified by geography and percent Latino voter population. The voters poll touched on issues specially relevant o the Latino community which where either represented in the November election or are subjected of on going local and national debate.
WCVI subsequently conducted its 1998 Election Turnout Study. Using the randomly-selected precincts identified for the exit poll conducted, actual counts of election day Latino voters were tabulated. Estimates of early voting by Latinos were used to develop a more accurate turnout figure. The results were weighted for a more exact estimate of total Latino turnout in California.
The margin of error for this study is +/- 4.8%. Results may not add up to 100% due to rounding. Margin of error higher for subgroups.
