The Big Mac Index is an informal economic index used to measure purchasing power parity (PPP) between different currencies. It is based on a simple concept: if the purchasing power parity theory holds true, then a Big Mac should cost the same in any country. The index was launched in 1986 by The Economist magazine and is published annually. In English-speaking countries, the index has given rise to the term "Burgernomics."

The index was introduced by Pam Woodall, an editor at The Economist, in September 1986, and the newspaper has published a new index annually ever since.

Significance of Big Mac Index
Intuitively reflects purchasing power parity: The Big Mac Index provides a simple and easy-to-understand way for the general public to understand the purchasing power differences between currencies of different countries. By comparing the prices of Big Macs in different countries, one can intuitively see which currencies are overvalued or undervalued.
Tool for popularizing economics: Due to its interesting and easy-to-understand nature, the Big Mac Index has become an important tool for economics education and popularization. It helps non-professionals understand the complex concepts of exchange rates and purchasing power parity.
Reflects the level of economic development: To some extent, the Big Mac Index reflects the level of economic development of a country. Countries with higher Big Mac prices generally have higher wage levels and living costs, which may indicate that the country's economy is relatively developed.
Although the Big Mac Index has some limitations, such as ignoring the impact of non-tradable goods and taxes, it remains a valuable economic indicator. It provides a simple and intuitive way for people to understand the purchasing power differences between currencies of different countries.
