Hi!

Can someone help me out with this?

According to JKR there are about 1000 students at Hogwarts ages 11 to 
17. There is no indication that there are any other Wizarding schools 
in the UK.

According to the CIA World Fact Book for 2003
(http://www.odci.gov/cia/publications/factbook/geos/uk.html)
the population statistics for the UK are:

Population: 60,094,648 (July 2003 est.) 

Age structure:
0-14 years: 18.3% 
15-64 years: 66.1% 
65 years and over: 15.6% 


Applying the above to number of students at Hogwarts:

1000/7 = 142.8571 students per year and the same amount enter 
Hogwarts every year meaning born every year.

Hogwarts' Years 1 through 4 has 571.428 students.
Hogwarts' Years 5 through 7 has 428.571 students.

142.8571 per year between 0-14 = 2,142.857 children in the 
Wizarding World newborns to 14 years old.
This is the 18.3%

That means that the 15-64 years group, which is 66.1%, is
equal to 7,740.047 people.

The 65 years and over age group, in this case, is 
1,826.698 people.

All in all, the total population of Wizarding Britain is
             
                11,709.602 people.

The number of children in the Weasley family is obviously 
unusual. So, my question.

Question: 

with the Muggle population of the UK being 60,094,648.0, 
how many Death eaters will Voldemort need over how much time 
to "raise" an army to conquer the UK and the world?

Thanks in advance.

Cheers,

Svetlana
