The problem is people will look at the price of, for example, fuel and say ohhh it’s gone up 20% how can that be.
They paid 119.9p last year.
They paid 143.9p today.
Last years price was a local minimum (say the average was probably nearer 126p over the year).
This years price was when they filled up at the services on the M1. The in reality (well in this example) average price for the year is 132p.
132/126=1.05=5% inflation.
But people don’t like common sense, they like sensationalist headlines.
Another example.
“Train fares reach £1000”
Yes, lands end to John O’Groats was £1000, but it still £2 from here to the next village.
Or to put it statisticaly, “OMG! Train fares have gone up 50,000%”
