Question about 男女比 order


How is 男女比 used in this example? Just like anything else in japanese context
matters and in this case the male/famale ratio is 6 male and 4 female, because
the text is talking about females are _coming back little by little_ in some
context.

> 少しずつ女性が盛り返してきていますが、いま男女比はだいたい６：４くらいです。

Am I mising anything? Is this complete bs?
