Depends, if it is separating two property's then it maybe required to maintain the Fire proof integrity, ie it will contain the fire for longer, it may also need to be 12mm thick board
If you are just lining a ceiling in your house then no, all you need to do is have the joists for fixings at about 500mm apart, also you could use 9mm thick Plasterboard

Sigle layer is fine, as many have stated, but none have pointed out that if your ceiling joist are spaced at 24" on center, then you definitely need to install 5/8" thick drywall. !/2" will sag because it can't sustain its own weight in that span. If the joists are 16" o.c. then 1/2" is fine.

Plasterboard has two uses, Sound resistance & fire Resistance. IT also comes in two common sized 9.5mm & 12.5mm. In general ceilings should have 12.5mm boarding (one layer), this gives 30 minutes fire protection & some basic sound resistance.
Be aware if you fill it with holes for downlighters & they are not fire rated, then you may have a problem.
The fire protection is only required to floors, not ceilings, ie if their is a room above.

I would not do it because of weight.
Sheetrock is heavy and difficult to put up on a ceiling. The double weight would cause you a lot of problems.
Painting is easy and a lot of people paint coat after coat on things thinking the paint has no weight. However, I have seen ceilings fall just because of the weight of the paint on them when they have been coated time and time again.

Number one stated it well. NO!
After installing thousands of sq. ft. of drywall I know this much. I'd rather hand off celings to someone else. No offense but why would it seem neccesary?
If sound deadening is the rationale, insulation above the ceiling drywall will certainly help.

No, you would use the same as the walls, however, there are a few differant thicknesses... I'm not sure the standard... If I were to hedge a guess it would be 5/16...

No, one layer is sufficient. Use at least 1/2" board, 5/8" would be better.

If there is a flat above you some building regs.require double thickness, (fire prevention measure.)

no a single 1/2" board is ok / code
in fire block area ( garage ) 5/8" fire rock is code where attaches garage touches common walls with attic & house!
