This week @pewresearch released an updated analysis of long-term trends in party identification. It's a great report and a must-read for anyone with an interest in U.S. politics. Let's take a look! (thread) 1/x

The balance of party ID among all U.S. registered voters has been fairly stable. Dems hold 49%-44% edge over GOP in leaned party ID in data running thru 2019. Comparable to other recent moments. But a lot is happening under the hood! 2/x 
The gender gap in party ID is now as wide as at any moment in @pewresearch data going back to 1994. Women are 14 pts more likely than men to identify or lean Dem. Avg gap was 9 pts between 1994 and 2014. 3/x
The #GOP holds 53%-42% edge in leaned party ID among white voters (a bounce back from low ebb around '07-'08). Dem Party holds wide advantages among other racial and ethnic groups, including overwhelming support among black voters. 4/x
Education has become fault line in U.S. politics. College grad+ voters lean Democratic 57% to 37%. ~25 years ago they leaned #GOP 50%-42%. In 1994, smaller gap between coll/non-coll voters. This is a big change! 5/x
Granularity to party ID within broad coll/non-coll groups. #GOP has made clear gains over time among voters with no college experience; less so with some college group. Dems gained among all coll+, but do especially well among those with postgraduate experience. 6/x
One trend that's gotten a lot of attention in recent years, is #GOP gains among whites without a college degree -- it's really striking! At same time, over last 25 years Dem Party has flipped balance of partisanship among white voters with college degree. 7/x
As with education among all voters, party ID gaps among whites within broad coll/non-coll groupings. Whites with lowest levels of educ break #GOP 2 to 1. Whites with postgraduate experience solidly Democratic. Whites with 4-year degree closely split. Big changes over time. 8/x
Party ID by gender + educ. A lot here. Women college grads have emerged as key Democratic group. Bigger gender gap among coll grads now than 25 years ago (even as both groups have moved Dem). 9/x
Kind of a complicated chart, right? Partisanship by gender + educ + race/ethn. One key finding is growing party ID gap among white women by educ. 55% of white women w/ no degree align #GOP vs. just 34% of white women with college degree. Wasn't much of a gap back in 1994. 10/x
Party ID by generation! Dem Party holds solid advantage among #Millennials (tho edge down a bit from high point a few years ago). Older generations are closely divided in their partisanship. 11/x
Party ID by generation and race/ethnicity. White #Millennials are more Democratic than older white cohorts, but remain roughly evenly split in their partisan preferences. This makes them *much* more likely than nonwhite Millennials to identify/lean #GOP. 13/x
Religious affiliation and party ID trends. So much here for a tweet (read the report!), but long-term movement to #GOP among white evangelicals and shift toward Dem Party among unaffiliated two highly salient political trends. 14/x
Voters who attend religious services regularly tend to be more likely to identify/lean #GOP than less regular attenders. (see Jewish voters especially, also white evangelicals and white Catholics). But pattern does not hold for all relig groups. 15/x
Place matters when it comes to politics. Rural voters now identify/lean #GOP 58% to 35% (big change from 1994!). Dem Party has grown advantage among urban voters. And the archetypal suburban voters remain closely divided in their partisan preferences. 16/x
Urban voters are more Democratic -- and rural voters are more Republican -- in all four regions of the country. But still variation. Look at trend among rural voters in South: Big long-term decline for Dem Party among this group. 17/x
How do the demographic makeup, or profile, of the two major party coalitions compare? #GOP is older, and aging more rapidly, than Dem Party. 56% of Reps are ages 50+, compared with 50% of Dems. Wasn't much difference back in 1996. 18/x
Profile of voters in U.S. is becoming much more diverse (though white voters remain clear majority). Share of all voters who are white, non-Hispanic has fallen from 85% in 1996 to 69% today. Dem Party increasingly more diverse than #GOP. 19/x
Dem Party voters are much better educated today, as a whole, than in 1996. Sharp drop in share with no college experience, growing % are college grads (but still less than half). Far less change in educ profile of #GOP. 20/x
Profile of party coalitions by race/ethnicity + education. Diversity and education up among Dem Party voters. In 1996, 58% of Dems were whites with no coll degree; today, 30%. Non-coll whites remain majority of all #GOP voters (57%). 21/x
How to summarize the differing areas of strength and weakness for #GOP and Democratic Party in party identification? This chart show some illustrative groups that help highlight some of the broader demographic correlates of partisanship in U.S. 22/x
Fin. That's it. Read the @pewresearch report -- it's great! 23/23 pewrsr.ch/2z8eSba
