If you’ve ever wondered how inflation is actually measured, the answer is surprisingly simple: statisticians look at what we buy.
Every year, the Office for National Statistics (ONS) updates its “basket of goods”, a list of around 760 everyday items used to track changes in the cost of living. And this year’s update tells a very modern story.
New additions? Alcohol-free beer, hummus, motorhomes, dashcams, and pet grooming.
This might seem like a random selection but it's not.
The basket isn’t about what should matter, it’s about what does matter to real consumers. If more people are spending money on something, it earns its place. If something falls out of favour, it gets removed.
So what does this year’s update tell us?
First, there’s a clear shift towards healthier living. The inclusion of alcohol-free beer and houmous reflects changing diets and lifestyle choices. People are drinking less alcohol, eating more plant-based foods, and generally becoming more health-conscious.
Second, technology is creeping further into everyday life. Dashcams, once niche, are now common enough to represent a typical household purchase.
Third, lifestyle spending is evolving. The rise in pet grooming reflects how people increasingly treat pets as family, especially after the pandemic pet boom.
And finally, there’s a subtle shift in wealth and leisure. Motorhomes joining the basket suggests more people are spending on flexible travel and experiences.
But here’s the key point for business students: inflation isn’t just an economic statistic, it’s a reflection of society.
The basket is essentially a mirror of consumer behaviour. And if you want to understand where markets are going next, this is one of the best places to look.
Because today it’s houmous and alcohol-free beer.
Tomorrow? It could be something entirely different.
So far, we’ve seen how inflation reflects changing lifestyles.
But for business students, the real value lies in understanding what sits behind these changes and why they matter.
What This Means for Business Students
If you’re studying business, finance, or economics, the inflation basket is central to how the economy works.
1. How inflation is actually calculated
The ONS tracks prices for hundreds of goods and services across the UK and combines them into the Consumer Prices Index (CPI), a key measure of inflation.
The UK government targets inflation of around 2%. Recently, it has been closer to 3%, higher than desired, and a sign that prices are still rising faster than planned.
Why does this matter?
Because inflation affects almost everything:
- Purchasing power (what your money can buy)
- Business costs and pricing decisions
- Wage negotiations
- Savings and investment returns
2. Why the basket keeps changing
The basket must evolve otherwise it stops reflecting reality.
Think about how quickly consumer habits change. If outdated items stayed in the basket, inflation would become a misleading measure.
Historically, the changes are striking:
- Wild rabbit featured in 1947
- Tea bags didn’t appear until 1980
- Today, we track dashcams and plant-based foods
Each update is effectively a snapshot of society at a point in time.
For businesses, this is incredibly valuable.
It tells you:
- What consumers are prioritising
- Where demand is growing
- Which industries are expanding or declining
In other words, it’s free, high-quality market insight.
3. The data revolution behind inflation
One of the biggest changes isn’t what’s in the basket. It’s how the data is collected.
The ONS is now using supermarket scanner data for more than half of grocery prices.
Instead of relying on thousands of manually collected prices, it now analyses millions of real transactions from supermarket tills.
This has two major advantages:
- Greater accuracy as prices reflect what people actually pay
- Better insights as trends can be identified much faster
For business students, this highlights a wider theme: data is transforming decision-making everywhere, not just in companies, but in government too.
4. Why inflation drives real decisions
Inflation isn’t just a statistic. It directly influences economic policy.
The Bank of England uses inflation data to decide whether to raise or lower interest rates.
- If inflation is too high → interest rates may rise to reduce spending
- If inflation is too low → rates may fall to stimulate the economy
These decisions affect:
- Mortgage costs
- Business investment
- Consumer spending
At the same time, inflation is used to adjust:
- Pensions
- Benefits
- Public sector wages
So even a small change in inflation can have a significant real-world impact.
5. The bigger lesson for business
The most important takeaway isn’t how inflation is calculated.
It’s what inflation reveals.
This year’s basket shows that:
- Consumers are becoming more health-conscious
- Technology adoption is accelerating
- Lifestyle and experience spending is increasing
- Data is becoming central to decision-making
- For businesses, the message is clear:
You must evolve with your customers.
Because if you don’t, you risk becoming the economic equivalent of “wild rabbit”. Once relevant, now forgotten.
Final thought
Next time you see an inflation headline, remember:
It’s not just about prices going up.
It’s about how society is changing, one shopping basket at a time.
