I have decided to write a blog with some fast facts about the people to use facebook. Facebook provides this information for free to everyone, if you know where to look ;)

DISCLAIMER: This is based on what people signed up as, and
therefore has a margin of error. I cannot guarantee exact
numbers.

Did you know that...

About 1 in 3 people living in Canada have a Facebook account,
compared to 1 in 10 of those who live in the USA.

An addition to the above: There are about 9m Canadian facebook accounts, and about 35m american ones.

There are a little over 500k men from South Africe, with almost 600k women.

There are 13.8m accounts registed in the UK, of which 44% are listed as men.

In Spain, 1.6m users are listed as over 18, and 16% of those are 'single'.

China has only 275k people (this is probably because of the blocking of free speech)

Less than 0.01% of people living in china have a Facebook account.

2.2m accounts in the US are owned by males in high school (which is about .75% of the us population).

Germany has about 1.1m facebook accounts, of which 475k are males, and 575k are female.

General facts:

Most facebook users are over 18 (apx. 2 in 3), however a lot of people lied about their age when they signed up, so this is probably a false statistic.

The US has about 30% of all accounts, the UK has about 18%, and Canada 14%. This accounts for more than half of all users.

More people on facebook are female than male (47-48/52-53 split is my estimate)

A small percentage of users don't have a gender listed (less than 5%)
