New SF demographic dataset:

Using precinct data for analysis: 

Using precinct data for analysis Different than poll data – reflects how people actually voted Issues with data: n ~ 570 citywide n = much less for districts (45-60) “Ecological Fallacy” Difficult to establish which characteristics are important in heterogeneous parts of SF

Correlations to PVI: 

Correlations to PVI PVI: high score means a more liberal voting population; low score means a more conservative voting population Some stronger correlations to certain characteristics Varies within districts (this is important!) More liberal Hispanic Younger voters More conservative Asian Older voters Higher income Higher homeowner percentage

Good correlations with district variation (inverse slope): 

Good correlations with district variation (inverse slope) % voters over 50 vs. PVI % owned housing units vs. PVI

Good correlations with district variation (positive slope): 

Good correlations with district variation (positive slope) % voters 25-29 vs. PVI Correlations are consistently stronger with demographics that vote more conservatively!

Not a good correlation, but with some district variation:

Looking ahead: 

Looking ahead SF will see increased proportions of Hispanics and Asians, from many countries. They will have a huge impact on the electorate, especially as immigrants become naturalized and are able to vote If, in general, Asians are more moderate than Latinos…
