"A nation’s war index indicates its capacity for violent struggle. For example, Afghanistan’s index jumping from 4.6 to 6.5 meant that every 1,000 males aged 55 to 59 were being replaced by 4,600 to 6,500 young men aged 15 to 19. These young men were ready and eager to compete for success in society and victory on the battlefield." #demography https://www.washingtonexaminer.com/weekly-standard/afghanistan-russia-and-the-war-index
