Most women I see in Orange County carry iPhone 6 Plus. My aunts bought them last year when first released. Phablets are more common with females for a couple reasons.
They carry purses, so no need to fit them in a pocket.
Women can hate texting on a smaller screen with long fingernails, so a wider keyboard is much easier to type on. It was a reason many couldn't enjoy the earlier iPhones and stuck to BlackBerry.
I think it was a brilliant move by Apple to appeal iPhone more to females. They live longer and there are more women on this planet than men. The largest demographic are females. Not any nationality like Chinese or Indians. Yet, 6 Plus is super popular over there too! The more Apple can appeal to females, the more dollar $ign$ they will be seeing. And not just women, anyone wanting a bigger screen size for whatever reasons like having weaker vision or realizing the many benefits from it.
