On May 10th Transparency International, an anti-corruption
outfit, published a survey of 15,000 Mexican homes on bribery.
It found wide regional variations. Palm-greasing was far more
common in and around Mexico City than in Baja California Sur,
suggesting more-populated areas have more unmet demand for
public services. Overall, Transparency reckons Mexicans paid 32
billion pesos ($2.5 billion) of bribes in 2010.
