What Is Inflation, Really?

Every few months, a new inflation figure lands in the news and politicians on all sides rush to claim it proves their point. But most coverage skips the basics. What exactly is inflation, who measures it, and why does it feel so different depending on where you live or what you buy?

At its simplest, inflation is the rate at which the general level of prices for goods and services rises over time. When inflation is high, each euro or dollar you hold buys a little less than it did before. Central banks, such as the European Central Bank or the US Federal Reserve, typically aim for an annual inflation rate of around two percent, low enough to keep prices stable, high enough to discourage people from hoarding cash instead of spending.

How Is It Measured?

Most countries calculate inflation using a consumer price index, or CPI. Statistical agencies track the cost of a large basket of goods and services, food, rent, transport, clothing, and compare it month by month and year by year. The composition of that basket matters enormously. If you rent a home in a big city, your personal inflation rate may be far higher than the official headline figure, which averages across many different households and spending habits.

There are also different flavours of inflation to know about. Core inflation strips out volatile items like food and energy to give a clearer picture of underlying price trends. Producer price inflation measures what businesses pay before those costs reach consumers. Each metric tells a slightly different part of the story.

Why It Feels Personal

The gap between official figures and lived experience is real, not imaginary. A retired person spending heavily on heating and medication will feel price rises very differently from a young professional whose biggest cost is a fixed-rate mortgage. This is why economists increasingly talk about distributional inflation, the idea that price changes do not hit everyone equally.

Understanding inflation does not require an economics degree. It requires knowing which questions to ask: what is being measured, who is most affected, and what tools exist to respond. Armed with those questions, the next headline figure will make considerably more sense.
