$1 in 1800 has the same "purchasing power" or "buying power" as $0.97 in 1806.

To get the total inflation rate for the 6 years between 1800 and 1806, we use the following formula:

CPI in 1806 - CPI in 1800CPI in 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.

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (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.
