iPhones in the US have an estimate ~55% market share depending on source. Owning an Android wasn't unusual in the least when I lived there, and appears to be pretty popular.

I don't think its unusual that a country with high median income and higher average income will tend to gravitate towards more expensive phones. Given that Apple doesn't make a cheap phone, it kind of follows that wealthier countries will buy more iPhones.

Of course the opposite is true as well, In a country where an iPhone is measured in months of salary, they won't sell well, but I'd be willing to bet that Androids in that price tier sell like shit in those countries too.

Is it a status symbol? arguably. But it also correlates pretty strongly with median income.
