National Survey Methodology

American Strategies designed this Internet survey of the top 50 metropolitan statistical areas in the United States. The
survey reached 3,000 adults, 18 years or older. The survey was conducted by YouGov on September 5-20, 2017.

YouGov interviewed 3210 respondents who were then matched down to a sample of 3000 to produce the final dataset. The

respondents were matched to a sampling frame of the top 50 MSAs on gender, age, race, education, ideology, and political
interest. The matched cases were weighted to the sampling frame using propensity scores. The matched cases and the

frame were combined and a logistic regression was estimated for inclusion in the frame. The propensity score function
included age, gender, race/ethnicity, years of education, ideology, region, and voter registration status. The propensity scores

were grouped into deciles of the estimated propensity score in the frame and post-stratified according to these deciles.

The sampling frame used for matching and weighting was constructed by stratified sampling from the full 2010 American
Community Survey (ACS) sample with selection within strata by weighted sampling with replacements (using the person

weights on the public use file). Data on voter registration status and turnout were matched to this frame using the November

2010 Current Population Survey. Data on interest in politics and party identification were then matched to this frame from
the 2007 Pew Religious Life Survey.

YouGov operates an online panel of over 4 million panelists across 37 countries. These represent all ages, socio-economic

groups and other demographic types which allows them to create nationally representative online samples and access hard
to reach groups, both consumer and professional. Their US panel has 1.8 million respondents.
