User guide:

The 'Select base currency' button allows you to choose from five base currencies: the yuan, the euro, the yen, sterling and the US dollar. You can also choose to see the index in its original 'raw' form, or adjusted for GDP per person. By default, the panel at the bottom displays a scatter chart plotting the local price of a Big Mac (expressed in the current base currency) against GDP per person in that country. Select individual points for details.

As you explore the map, the scatter chart will be replaced by a line chart plotting the highlighted country's under- or over-valuation against the current base currency over time. You can select a country on the map to 'freeze' it (with the exception of Internet Explorer), allowing you to mouse over/tap the line chart and see detailed indicators for your selection over time. To 'unfreeze' the map, click/tap on the highlighted country again.

NOTE: As of January 2014, the Big Mac index has been adapted to include Latvia as part of the euro area. South Africa’s Big Mac price has been revised.
