Quite simple: 31L is 11,248 ft. long, while 31R is 8976 ft. long.
It makes most sense to use the longest runway for takeoffs.
About the noise abatement, you don't have to rich in order to have the right to protest if the noise levels grows to high. There ARE plenty of houses around JFK, and since the 31L Canarsie Climb departure almost at once takes you out over the oceans, it makes more sense, in my view, to use 31L over 31R.

The departure procedures for 31L and 31R are the same: a left turn towards Canarsie. So there would be no point in sending traffic off of both runways if the traffic had to be staggered anyway. Typically, 31L is used for departures and 31R for arrivals. Also, there is little room for taxiing aircraft near the departure end of 31R, while there are long parallel taxiways leading to 31L. Looks like geometry more than noise is the issue.

I think it might also have something to do with the restrictions put into place after the Belle Harbor crash last year. Apparently, they were going to get rid of most of the air traffic over that spot to ease peoples' worries.

Frequentflier, even before the crash of AA587, Belle Harbor was always under the departure route of JFK. 31R is occasionally used for departure, but only limited to Saab 340 (American Eagle). After the departure, most Saab 340 are vectored toward NE bound byt the tower, so you won't be able to see their departures.

Simpson, sayign that Belle Harbor is under the departure route is like saying that planes should not fly over Ohio. Have you ever seen how high up the planes are by the time they reach Bele Harbor? The noise at that point is almost nil.
I'm not expert at measure altitude by sight, but those planes have to be at least 2 or 3 thousand feet up already. It takes the plane a couple minutes to even get over Belle Harbor.
East Coast, yes, granted for LGA Rwy22, but what about from August 26th to September 8th, during the US Open, when planes departing on 13 will be making a SHARP left turn upon liftoff and going directly over College Point (my town). THAT is because of the US Open people being rich.
Diverting air traffic from over 10,000 whiny rich people to go over a town over 100,000 instead?

Phil, it's simple. Us rich white folk do not particularly like the engine noise from airplanes, let alone at a tennis match while sitting there sipping our tea. You see, once you we leave the Upper East Side, we need to travel around with personal bodyguards in our Lincoln Towncars, because, frankly, the city has become too dangerous to get around alone. Getting back to the airplane noise, you see, it is more beneficial to have the airplanes affect the 100,000 so called "College Pointians" who live in shacks along the crime ridden streets, than affect the level of play at the US open, and the 10,000 people watching. This is the reason for the plane diversions. It's always such a task to enlighten the less "fortunate" people, but it gives me such a special feeling.
