### Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1800 would be equivalent to £0.86 in 1802, an absolute change of £-0.14 and a cumulative change of -14.07%.

Compare these numbers to the US's overall absolute change of \$-0.15 and total percent change of -15.08%.

### 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 1800 and 1802.

Compare these values to the overall average of -7.85% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1800 → 1802
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
Medical care 0.00 0.00 1.00
Recreation 0.00 0.00 1.00
Education and communication 0.00 0.00 1.00
Other goods and services 0.00 0.00 1.00

For all these visualizations, it's important to note that not all categories may have been tracked since 1800. This table and charts use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1800 to 1802

This inflation calculator uses the following inflation rate formula:

CPI in 1802CPI in 1800
×
1800 USD value
=
1802 USD value

Then plug in historical CPI values. The U.S. CPI was 12.6 in the year 1800 and 10.7 in 1802:

10.712.6
×
\$1
=
\$0.85

\$1 in 1800 has the same "purchasing power" or "buying power" as \$0.85 in 1802.

To get the total inflation rate for the 2 years between 1800 and 1802, we use the following formula:

CPI in 1802 - CPI in 1800CPI in 1800
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

10.7 - 12.612.6
×
100
=
-15%

### News headlines from 1800

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

• First session of Congress held at under-construction Capitol building in Washington D.C.
• First cowpox vaccination (for smallpox prevention) in the United States. The vaccine was given by Dr Benjamin Waterhouse to his son.
• The free African American community of Philadelphia submits its first petition to US Congress for the abolition of slavery.
• Barnaba Niccoclo Maria Luigi Chiaramonti elected pope, taking the name Pope Pius VII.
• A Smallpox vaccine is invented by Doctor Benjamin Waterhouse leading to the first immunization against the disease.
• Congress holds its first session in the, at the time, still incomplete Capitol building in Washington D.C.
• The French army defeats the Turks at Helipolis, after which they advanced on to Cairo.

### 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.
