Army Sizes and Mahabharata Loss

The table below shows the army sizes as given in an Amarakosha commentary. Even if we assume about 40 million population in the Indian subcontinent 7000 years ago, a simple calculation shows about 15% of that population was wiped out due the Mahabharata war that lasted just 18 days.
