Every demographic
within the set of registered Republicans in New York.
There's still a few votes left to be counted but 98% of precincts have reported so this is close enough:
858,245 voters voted in the Republican primary, and 1,790,301 voter voted in the Democratic primary. (Trump got 518,816 votes, Clinton 1,037,380, essentially 2:1.)
Then look at the percentages:

http://edition.cnn.com/election/primaries/polls/ny/Dem
56% of the Republican voters were men and 91% were white.
59% of the Democratic voters were women and 59% were white.
24% of the Republican voters were age 44 or younger.
41% of the Democratic voters were age 44 or younger.
So if we apply the percentages to the total votes received, about 215,248 women voted for Trump and 665,455 voted for Clinton; she won by more than 3:1 among women.
Anyway, my point is that that particular paragraph in that Guardian article gets it mostly wrong, because the demographics of the Republican primary voters are not the same as those of the general electorate (and even there, he still did better among men than he did among women).
