Historical analysis of the Paraguayan War shows that its aftermath drastically reduced the male population in Paraguay. Reliable sources suggest that around 28,000 adult men were left after the war, confirming the claim about significant male population loss, albeit with a slightly different estimate from the claim. Additionally, in specific areas, the female-to-male ratio reached as high as 20:1, corroborating historical accounts about the demographic impact. However, the current demographic statistics significantly differ, and the present female-to-male ratio is no longer as extreme, reflecting changes over time. Overall, the claims regarding the war's immediate effects on demographics are factual, supported by historical records, but it is essential to distinguish these past figures from current statistics.
