GDP no longer tells the whole story

Gross Domestic Product (GDP) falls short when it comes to measuring wellbeing or real economic activity. Its calculation, centred on market value, ignores key aspects of production and consumption.

## GDP and its value trap

For decades we have relied on **Gross Domestic Product** as the great measure of a country's economic health. It is the figure we are given on the evening news, the one that sets the trends and that supposedly tells us whether we are doing well or badly. But what if I told you that this indicator, as we use it, could be a trap? Imagine a country where a single item is bought for **50 dollars**. GDP rises by that amount. Now think of another place where **ten people** buy ten items at **5 dollars** each. GDP also increases, adding up to **50 dollars**. In the first case, we have one item; in the second, ten. The market value is the same, but the quantity of goods and services produced and consumed is very different.

## Beyond market value

The fundamental problem is that GDP focuses on the monetary value of what is produced and sold, paying little attention to the actual quantity of goods or the wellbeing they generate. If a country produces large quantities of something very cheap, its GDP may be low, even though the population has access to far more goods and services than in another place producing smaller quantities of something very expensive. It is not just a question of how many dollars are moving around, but of how many things are moving and whether those things actually improve people's lives.

## Population matters, and a lot

Moreover, GDP does not always take population size into account. Comparing the GDP of a country with **one billion inhabitants** with that of another with **350 million** without adjusting for population size can lead to flawed conclusions. While total GDP may be high in the larger country, income per person could be significantly lower. The debate becomes even more complex when you consider that GDP is not the only indicator of economic activity or "health", and that its interpretation needs to be nuanced.
