They don't, insofar.
What's with the Pokémon Tower, Mt. Pyre and the like, then?
Anyway, like KP said, it would depend on the species. I would imagine that Bug types live very short lives while ones like turtles or dragons would live much longer, for example.

They could have died from an accident, not necessarily of old age.
That is not what the question is asking. Not at all.
1 year you say? That doesn't seem like a lot.
I would guess that legendaries are immortal.
No, no; in some countries, (trying not to say bad things...) a "." means a comma, so when they say "2.444.566", they mean "2,444,566" and they use commas for decimals.
Anyway, Ninetails is said to live for 1,000 years. I'm sure the "when" Pokemon
dies depends on how experience they have, and their environment, kind of like people.
