What places have the best efficiency for EV training in Black And White?

I've decided to look into EV training to make my Pokemon stronger in a competitive battle. I know about how to train EVs, using items such as Macho Brace or Power Bracer etc, but I was wondering what routes/caves/surf areas/other places were best for each specific EV stat.

My version is Pokemon Black, and I've beaten the Elite 4 and Alder and have access to all areas of the game.

I know that on Route 1, all you can find are Lillipup and Patrat, both of which give +1 Attack EV.
That makes for a 100% chance to get +1 Attack EVs per kill.

I also know that in the cave beside Route 3, all you can find are roggenrola and woobat, which give +1 Defense EV and +1 Speed EV respectively.
This results in only a 50% chance to get +1 Defense EV per kill, or a 50% chance to get +1 Speed EV per kill.

I'd like to know where all the statistically most rewarding places to find each EV are, to minimize the time it takes to EV train.
I believe I know already that route 1 is the best for Attack, but I would also like to know about Defense, Special Attack, Special Defense, Speed, and Health.
