None. They die because someone does something to cease their ability to live.
As of recent estimates, there are approximately 400 million registered firearms in the United States. This number accounts for both registered and unregistered firearms, as many states do not require registration.

No, there isn't.
Oregon doesn't have registration of Title 1 (i.e., "normal") firearms - only NFA items must be registered. You can own as many as you can afford.
Not really possible to answer, since the question assumes registration of firearms. In MOST of the United States, there is no requirement for registration of firearms (No matter what they show on TV). The exception are weapons such as machine guns, short barreled rifles, short barreled shotguns, etc. These have been required to be registered with the Federal BATFE since 1934. For machine guns, there has been ONE murder committed with a registered firearm since 1934. That case involved a police officer that was convicted of murdering his wife.

Unless stolen before making it to a retailer, they all are when bought. --- Firearms are not registered when sold by retailers (FFL dealers) unless they are required to be registered in a particular state. And the registration is usually done by the local police department in those states. FFL dealers record the buyer's information from form 4473 in their "bound book" and then they are obligated to keep these records for as long as they remain in business and keep their federal firearms license renewed. Gues it all depends on what the OP meant by "registered"
