As a member of the North American Free Trade Agreement, Mexico has a competitive advantage over its Latin American neighbours. Its 101 million citizens enjoy the highest purchasing power in the region, while sound macroeconomic management has kept the economy resilient. Mexico's GDP is $637.2 billion, of which 67.9% is contributed by the service sector. Mining contributes just 1.2%, but oil accounts for 9% of total exports. Some 45 million Mexicans live on less than $2 a day (and 10 million survive in extreme poverty).
That's not much by UK standards, but globally Mexico is considered to be a middle-income country. Almost 75% of Mexicans live in urban areas. To minimise the risk of robbery and kidnapping, it is common in Mexico City to hire one trusted taxi-driver by the day, week or month rather than different taxis for individual journeys.
