Melrose is probably 20 to 25 percent Italian and the rest is Mexican. It's a shame, another good neighborhood that changed. And grave ave is not defunct, still many active guys around.
As of 2010 it was only 22 percent non Hispanic white total, which means probably even less now.
And usually when a city or neighborhood changes like that and only a few whites are left, it is almost all old people who stay.
Walk down 19th Street, the old "main drag." It is a hellhole. You'll see virtually no Caucasians whatsoever. I went to the Mt Caramael feast this year and it is pretty much dead as a celebration of Italian American culture.
