This dataset provides composite consumer price index figures covering the period from 1750-2023. It is primarily intended to provide the backend for a simple inflation calculator program, and for making historical comparisons.

Series information: - Year: The year. - Composite index: This is a composite consumer price index built from previous indexes to provide coverage over a longer time period. - Annual difference: The difference between this row’s composite index value and that of the preceding year. - Percentage difference: The annual difference expressed as a percentage. - Cumulative change since 1750: The cumulative difference in inflation since 1750. - Difference from today: The difference in index value between the given year and 2023.

Guide

You can use the dataset to answer the following types of questions, in the following ways:

What is the equivalent sum of money in year X (2003) prices of £50 in year Y (1850)?

This can be determined by how much prices have risen over the relevant period. It can be calculated by: Amount to be revalued multiplied by later year’s index divided by earlier year’s index. For the above example, £50 x 715.2/8.4 = £4,257

What was the purchasing power of the pound in year X (1995), compared to 1965?

100 times earlier year’s index/later year’s index. 100 x 58.4/588.2 = 9.9p This can be reversed by inverting the numerator and denominator in the above equation, to give the earlier year’s value in the latter year.

One United States dollar was worth over ********* Indonesian rupiah in September 2025, the highest value in a comparison of over 50 different currencies worldwide. All countries and territories shown here are based on the Big Mac Index - a measurement of how much a single Big Mac is worth across different areas in the world. This exchange rate comparison reveals a strong position of the dollar in Asia and Latin America. Note, though, that several of the top currencies shown here do not rank among the most traded. The quarterly U.S. dollar exchange rate against the ten biggest forex currencies only contains the Korean won and the Japanese yen.

Context

Demand for houses has exploded in the UK in the last two years due to the pandemic. As a result, it feels like it is becoming more difficult for young people to afford to buy a house in the near future. I wanted to collect data to see if this sentiment is backed up by numbers.

Content

In this folder you will find the average house price in the UK between between 1975 and 2020, the median wage in the UK between 1999 and 2020. Both of these metrics have been adjusted by inflation up to 2020.

This folder also contains a table containing data on the wage gap in 2021, in the UK and by age group.

At **** U.S. dollars, Switzerland has the most expensive Big Macs in the world, according to the January 2025 Big Mac index. Concurrently, the cost of a Big Mac was **** dollars in the U.S., and **** U.S. dollars in the Euro area. What is the Big Mac index? The Big Mac index, published by The Economist, is a novel way of measuring whether the market exchange rates for different countries’ currencies are overvalued or undervalued. It does this by measuring each currency against a common standard – the Big Mac hamburger sold by McDonald’s restaurants all over the world. Twice a year the Economist converts the average national price of a Big Mac into U.S. dollars using the exchange rate at that point in time. As a Big Mac is a completely standardized product across the world, the argument goes that it should have the same relative cost in every country. Differences in the cost of a Big Mac expressed as U.S. dollars therefore reflect differences in the purchasing power of each currency. Is the Big Mac index a good measure of purchasing power parity? Purchasing power parity (PPP) is the idea that items should cost the same in different countries, based on the exchange rate at that time. This relationship does not hold in practice. Factors like tax rates, wage regulations, whether components need to be imported, and the level of market competition all contribute to price variations between countries. The Big Mac index does measure this basic point – that one U.S. dollar can buy more in some countries than others. There are more accurate ways to measure differences in PPP though, which convert a larger range of products into their dollar price. Adjusting for PPP can have a massive effect on how we understand a country’s economy. The country with the largest GDP adjusted for PPP is China, but when looking at the unadjusted GDP of different countries, the U.S. has the largest economy.
