Well, every birth inevitably leads to a death, whilst guns might but they're not guaranteed to.
So obviously, you need to keep track of the most deadly kind of people, pregnant women, more so than a not quite as deadly kind like gun owners.
True, the case can be made than a single gun can result in multiple deaths whilst a birth will only ever result in a single death, but none the less the statistics don't lie and they show that a lot more deaths can be traced back to a birth than they can to gun ownership.
I once watched a woman walk into a supermarket just openly being pregnant. Fortunately she behaved, because some of the other folks were concealed pregnant.
