readx;? Regarding the wizarding population, Rowling told us that there were more than 3,000 people in the United Kingdom. Pen Fun Pavilion wWw. ｂiquge。 info And I studied the original book carefully, the prisoner mentioned that three-quarters of Hogwarts students support Gryffindor, and only 200 support Slytherin, so the school should have more than 800 students, the offset of international students and going abroad, Hogwarts is the only school of witchcraft and wizardry in the UK, so these 800 people can be considered all the wizarding population between the ages of 11 and 18 in the UK. In addition, the number of o.w.ls exams is more than 100, excluding some who did not take the exam, such as Susan Bones, which is almost 800

This part of the population is equivalent to the age of primary and secondary school students, according to the proportion of China's primary and secondary school student population of 16.67%, the proportion of 11-18 should be about 12%, plus the aging of the population in the United Kingdom, then this proportion should be below 11%, and the population of British wizards should be about 7,300 at 11%.

In 1991, the population of Britain was 57 million, and according to this ratio, China's population in 1991 was 1.23 billion, so the population of wizards should be 158,000. Coupled with the existence of black households in China, I write 200,000 is not much.

When I was writing this, I asked a colleague that the proportion of the population aged 0 to 18 in the UK should be 19%, and the proportion of the population aged 11 to 18 should be less than 10%, so the wizard population in the UK should be around 8,000. Then China's wizard population should be 173,000, plus China's family planning, the black household population is large, so 200,000, that's how I calculated it at that time.;
