if there are 1,000 students in the school, there would 
normally be about 15,000 wizards and witches in the country, as it's 
the only school and would therefore include everyone in the 11-16 age 
range and, probably, most of the 16-18 year olds too. However, as 
wizards live longer than Muggles, maybe there are more. 
 
Does anyone know?

Kneazle:

My badly estimated guess is a UK WW population of around 60,000.

20% of families with school age kids
10% with kids younger than school age
70% with no school age kids or no kids at all (including couples, 
singles, those with older kids)
