I've gotten the impression that underage magic is detected based on
the area where the underage wizard lives.  Otherwise, Harry wouldn't
have been able to perform magic with Dumbledore in the cave without
giving away their positions.  I don't think the ministry can detect
who performed the magic (like Dobby and the pudding), but becomes
suspicious when a spell is detected in the proximity of the dwelling.
 I'm not sure how this works in houses or areas where a lot of wizards
reside.
