Mainly because Liverpool and the Metropolitan Borough is more than twice the size of Newcastle and it's borough. 466,000 vs 189,000
Then you look at Liverpool and the surrounding Boroughs, Sefton, St Helens etc and those are even larger than the comparable Newcastle boroughs (Tyneside). 2m vs 0.8m
A fair point, but that only really influences the fan count point.
Chico's point about them all thinking Newcastle are big everywhere because everyone in Newcastle supports them (or words to that effect... I don't really pay too much attention to chico) is still relevant.
Not having a rival in the same space is bound to breed a different mentality to the likes of us, when we constantly see strangers, friends and family supporting the team we hate most. Everton's stature is challenged most in the city of Liverpool, whereas Newcastle's stature is exaggerated most in the city of Newcastle.
