In regards to the Wizarding population: given the present article has Rowling putting the number of wizardfolk in the UK at about three thousand, and given that the population of the UK, rounded down for a clean number, is roughly sixty millions, would it be a stretch to say, in the Harry Potter universe, there is a witch or wizard for every twenty thousand people? --Maharet.alexander 23:04, December 15, 2009 (UTC)
If I were to guess on the wizarding population I would guess about 100 million or more, this is based on the information given on the Europe Potter Wiki page where it states that there are atleast 100.000 wizards and witches in Europe and 730.000.000 Muggles. The Wizard population in this area being 0.014% of it's muggle counter I felt it right to assume that the total Wizard population be the same .. so 0.014 x 6 775 235 700 = 94 853 299.8 Jackdd111 19:57, September 2, 2011 (UTC)
Pure-blood marriage = incest?
"The practise of pure-blood intermarriage left many with mental illness caused by incest."
First of all Pure-blood marriage are NOT incestuous, UK law say only that marriage between a person and their parent, grandparent, child, grandchild, sibling, uncle, aunt, nephew or niece, of the whole or half blood is prohibited (and therefore incestuous).
Pure-blood marriage may however be inbreeding, which can cause mental illness, but do we have anything to back up that it there is widespread inbreeding yet along that it caused widespread mental illness among the pure-bloods? —The preceding unsigned comment was added by 188.8.131.52 (talk • contribs).
A marriage between cousins is not incest. It is allowed. But when you always marry your cousins, that is not forbidden, but it leads to the mental illness which suffer those from an incestuous relationship. O. k., it may not be incest, but very close to this.
