If I could teleport wherever I wanted, I would be nowhere near a city.

I agree with some of the points here, but a lot of people don't buy Rowling's claim that there are only 3,000 wizards in Britain. For one thing, she's also said that Hogwarts has about 1,000 students, which obviously doesn't fit. Wizards have long lives and usually don't have big families, so there's no way 1/3 of the wizards are between 11 and 18. Rowling admitted she's not good with numbers, so her estimates really shouldn't be taken seriously either way.

Quidditch is one of the biggest indications that there are more wizards. Given that there are 14 Quidditch teams in the British and Irish league and the teams seem to have reserve players, that would mean a ridiculous percentage of British and Irish wizards are professional athletes and each team would only have a couple of hundred fans at best. And we see that Hogwarts Quidditch players moving onto pro level is quite rare. The number of people at the Quidditch world cup final doesn't track with there being 3,000 British wizards either. It's implied that getting tickets is a major privilege (and given that there are only two other major magic schools in Europe, it's unlikely that Britain is unusually non-magical), so 100,000 wizards at the world cup only makes sense if the British wizard population is much bigger.

The general wizard economy doesn't seem like it would work with only 3,000 wizards. Diagon alley is far too big to be a commercial centre for such a small population. The ministry of magic has too many employees. 3,000 people is probably too small for a daily newspaper as well (let alone an additional rival paper).

And then there's the fact that Vernon Dursely sees so many wizards casually walking around while he's driving home in the prologue of the first book. There are clearly a lot of them hiding among the muggles.

The wizarding world makes a lot more sense if the population is in the tens of thousands - maybe towards the lower end, like 20 or 30k. You might be able to make a case for it being 3k by doing a lot of mental gymnastics, but it's much easier to just assume Rowling's figures are unreliable.

The irony is that the Malfoy Family originally descended from a court magician to a noteworthy king; with the Malfoys being one of the most largely beloved and influential groups among the Muggles in the time before the Statute of Secrecy was implemented. A real tragedy of the bloodline.

Here’s also a reason they can’t be in one place. Like any community making it easier for your enemies to wipe you out can’t be allowed

Cities have too much chaos and bring ALOT of unwanted attention

Bro just get a small abandoned shack put a charm to not let muggles in and expand it by like 100,000,000

that 3,000 number has been a mistake that JK admitted to making without fully comprehending her vision of the setting yet. The actual numbers based on the stories and decisions/comments by JK is 20,000-30,000 in Britain.

This whole video can be summarised in one answer

"They don't need to"

This in itself is one reason why the Wizarding World makes no sense.

If the majority of witches and wizards live in Muggle towns and cities, they should all be well integrated into Muggle culture: every time a house is a built, or they need to buy groceries, or simply walking out of your own front door, you'll be wearing Muggle clothing. You'll be using Muggle money for four fifths of all economic transactions.

You'd only go to Diagon Alley to buy eye of newt or Floo Powder.

If you live in London, it's inconceivable that you wouldn't have an Oyster card, wizard or not.

As for jobs, the Wizarding World as written cannot support itself: bankers without economics degrees, journalists, authors and publishers who've never studied English Language or Literature; potions makers and alchemists in an economy where literally everyone has studied how to make potions at school;

Heck, people even having regional accents when they were all educated at boarding school for 7 years.

Technically the world we see in London after the first fall of Voldemort is a shadow of what it was before Voldemort.
In a flashbacks to when Harry’s parents were in school flitwick was collecting tests and hundreds of students tests came to him. When Harry was in school however flitwicks class had like 10-20 students.
The reason there’s only like 5000 wizards in England is because of Voldemort.

If you played the video games you'll find out there is a village In the highlands most of that is the magical community

You know when you're traveling and you pass through a small town that gives you a palpable feeling of unease (but not danger) and you feel that you need to leave? That's a wizard town and the muggle-repelling magic is at work.

The thumbnail looks like Gondolin. A hidden city surrounded by mountains.

Now I have more questions about how the Ministry of Magic works.

With only 3000 wizards, after 6 or 7 generations most of them would be related. So the older pureblood families are more than likely inbred

If we take the share of wizards compared to Britain's population as of 1997, it's 0.0052. Which means that,  applying this to Earth's 8 billion people, there would be about 416,000 wizards worldwide.

0:05 That is an unsustainable population.

Rowling's estimate is probably just the ignorance of Harry's aristocratic environment.  The people she's talking about are the equivalents of scientists and engineers in the Muggle world, not just people allowed to know about magic at all.  With the numbers she's talking about, the Wizarding War is barely a fight among street gangs.

That’s just Britain alone. Maybe not even Ireland but Britain itself. We don’t know about the other countries. I mean MACUSA looks like it’s in New York but for all we know there has to be a few settlements, especially for the countries with a more superstitious muggle population- or a government with control over WMD like nuclear warheads.

This right here is the entire reason why the fact that many of these magical beings have absolutely no clue. As to how technology works! Makes absolutely no sense
