From my experience, more 18-25 males without kids would go for the Cupra Born if they wanted an EV, rather than a Tesla with costly insurance and higher purchase price.
Tesla's are the more likely choice EV for 25+ males especially with family, if budget allows.
The fiat 500e or Abarth 500e could fit the 18-25 demographic, more females seem to drive the fiat 500 petrol models so this might follow with the EV.
I'm pushing 30,M, with 2 kids under 7 and the MG4 Trophy will be my first EV (collect it this week!!) and first brand new car for a number of years, since I had a 15' plate Mazda 6 2.2 which was very nice. I've been driving a MK3 Honda CR-V EX Diesel for a number of years and it's been great. I use it as a van which I'm going to miss with the 4.
But.. I would have a Tesla Model S or X if I could justify it (I love them) and had the finances set up for it. Fact of the matter is the MG4 seems to be a great value for money car, for a first EV, which drives nice, and when everything works as it should - has everything you could need from a brand new EV.
