What statistics do we have of how many people pre-farming (before~7-10k BC) died early due to starvation or malnutrition?

[jojobas]

We know they voluntarily killed ~30% of all newborn, so there's that. Perhaps another 30-50% died before age 18.

These numbers are not unique to Australia, it's considered to be commonplace in hunter-gatherer societies.
