Interestingly I have seen a high share of iPhone Minis in my tech-affine bubble around Berlin / Amsterdam etc. - also my grandma switched from SE to 13 Mini.

Also bought used iPhone SE (2016) in 2019 and 2020 - both time from (UX) designers - but the same people also ride bicycles, trains - or if car, really reflect their user requirements - be it a small EV or a van for vanlife.

Average consumers just buy the largest, most marketed (high margin) or "whatever the neighbour has" option - aka SUV or Pro Max.
