Two outliers, opposite corners
Every party × income-third × college cell, placed by its weighted mean on the economic index (horizontal, right = more economically conservative) and the social index (vertical, up = more socially permissive). The origin is the national center; larger rings mark the two cells furthest from it. GSS, pooled 1972–2024.
Takeaway: the cloud is not a diagonal line. The affluent college Democrat floats to the top-left (socially permissive, economically moderate); the affluent college Republican sits at the right (economically conservative, socially middling). They are unlike each other and unlike everyone else — on different axes.
ANES finds the same two corners
The identical construction in the ANES Cumulative File. The outliers are again the affluent college-educated Democrat (top) and the affluent college-educated Republican (right).
Takeaway: two independent surveys, built from different question wordings and weighted differently, place the same two cells in the same opposite corners.
Where each group stands on this question
Weighted mean for every party × income-third × college cell, in standard deviations (right = the conservative or traditional side, oriented to match the index).
Does income move the parties the same way?
The question’s weighted mean across income thirds, one line per party. Diverging lines mean income sorts the parties differently on this item.
