Mystery of absent Mexican teachers and other startling numbers of 2014

This is the amount that the UK's Office for National Statistics (ONS) estimated that prostitution contributed to the economy in 2012, following a decision by the EU that prostitution and illegal drugs should be counted as part of a country's Gross Domestic Product.

The ONS estimates that:

- about 61,000 people work in prostitution in the UK

- the average cost per visit is about £67

- each prostitute sees about 23 clients per week, working 52 weeks a year - in total about 1,200
