### Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1810 would be equivalent to £0.72 in 1821, an absolute change of £-0.28 and a cumulative change of -28.47%.

Compare these numbers to the US's overall absolute change of \$-0.08 and total percent change of -8.13%.

### Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1810 and 1821.

Compare these values to the overall average of -0.77% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1810 → 1821
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
Transportation 0.00 0.00 1.00

### How to Calculate Inflation Rate for \$1, 1810 to 1821

This inflation calculator uses the following inflation rate formula:

CPI in 1821CPI in 1810
×
1810 USD value
=
1821 USD value

Then plug in historical CPI values. The U.S. CPI was 12.3 in the year 1810 and 11.3 in 1821:

11.312.3
×
\$1
=
\$0.92

\$1 in 1810 has the same "purchasing power" or "buying power" as \$0.92 in 1821.

To get the total inflation rate for the 11 years between 1810 and 1821, we use the following formula:

CPI in 1821 - CPI in 1810CPI in 1810
×
100
=
Cumulative inflation rate (11 years)

Plugging in the values to this equation, we get:

11.3 - 12.312.3
×
100
=
-8%

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.

### Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
