£1 in 1810 is equivalent in purchasing power to about £0.97 in 1811.
The pound had an average **deflation** rate of -2.78% per year since 1810, producing a cumulative price change of -2.78%.
Purchasing power *increased* by 2.78% in 1811 compared to 1810. On average, you would have to spend 2.78% *less* money in 1811 than in 1810 for the same item.
This is an example of **deflation**.

This means that prices in 1811 are 2.78% lower than average prices since 1810, according to the Office for National Statistics composite price index.

The 1810 inflation rate was 2.86%. The inflation rate in 1811 was -2.78%. The 1811 inflation rate is lower compared to the average inflation rate of 2.13% per year between 1811 and 2021.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1811 was 14.00. It was 14.40 in the previous year, 1810. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1811 CPI is less than 1810 CPI, negative inflation (also known as deflation) has occurred.

Politics and news often influence economic performance. Here's what was happening at the time:

- Buenos Aires citizens discharge the Spanish Viceroy, Cisneros in the May Revolution.
- Grito de Dolores was issued, calling for the end of Spanish rule in Mexico. The event is celebrated as Mexican Independence Day
- Andreas Hofer a Tyrolean patriot and the leader of a rebellion against Napoleon, is executed.

Raw data for these calculations comes from the composite price index published by the UK Office for National Statistics (ONS). A composite index is created by combining price data from several different published sources, both official and unofficial. The Consumer Price Index, normally used to compute inflation, has only been tracked since 1988. All inflation calculations after 1988 use the Office for National Statistics' Consumer Price Index, except for 2017, which is based on The Bank of England's forecast.
