A part of it, I think, is the small numbers the wizards have.
When a single year of Hogwarts students would be lucky to scratch around 100 students they just don't have that many people, even if on the average they live long. Wizarding population numbers, going by canon at least, would not get even close to 100 000 people in the whole of the UK at a guess. In such a case, even a dozen dead is a tragedy and a major blow to wizarding society.
