Perhaps an interesting dataset. I do not understand the inspiration behind the presentation. Flags outside a select group are not universally or quickly understood. The ratio question is it area is it linear dimension will my brain guess right. My thought plot x-y all countries y axis ratio, x axis income, add a linear fit and look for a trends and outliers like Liechtenstein. Yeah what is going on there. A guess perhaps the country leans conservative and it is obviously rich so young women have the resources to leave to avoid the incels.
