Generally he did quite poorly in the suburbs (this is why he came up short in FL, NV, and OH), and at the time there was a lot of hand-wringing about how 95 of the 100 fastest-growing counties in the country had voted Republican. Of course, those areas were all devastated by the subprime collapse and haven't been nearly as strong for the GOP since.
I've also come across 97 of the fastest-growing counties that Bush won, which seems to be population increase between 2000 & 2004. Of those counties, Hillary won 13 of them in 2016 & Obama won 14 of them in 2008
'08 Obama won 2 more counties than Hillary in Illinois (Boone & Kendall) and Florida (Flagler & St. Lucie).
Conversely, Hillary won 2 more counties in Georgia (Gwinnett & Henry) as well as Fort Bend, Texas.
