## Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1840 would be equivalent to £0.90 in 1842, an absolute change of £-0.10 and a cumulative change of -9.91%.

Compare these numbers to the US's overall absolute change of \$-0.06 and total percent change of -5.75%.

## Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes. This chart shows the average rate of inflation for select CPI categories between 1840 and 1842.

Compare these values to the overall average of -2.92% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1840 → 1842
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00

## How to Calculate Inflation Rate for \$1, 1840 to 1842

Our calculations use the following inflation rate formula to calculate the change in value between 1840 and 1842:

CPI in 1842 CPI in 1840
×
1840 USD value
=
1842 USD value

Then plug in historical CPI values. The U.S. CPI was 8.7 in the year 1840 and 8.2 in 1842:

8.28.7
×
\$1
=
\$0.94

\$1 in 1840 has the same "purchasing power" or "buying power" as \$0.94 in 1842.

To get the total inflation rate for the 2 years between 1840 and 1842, we use the following formula:

CPI in 1842 - CPI in 1840CPI in 1840
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

8.2 - 8.78.7
×
100
=
-6%

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

• Identification of Antarctica as a new continent by American naval expedition lead by Charles Wilkes.
• Charles Wilkes discovers Antarctica in an American naval expedition.
• Charles Wilkes discovers the Shackleton Ice Shelf in Antarctica.
• The world’s first postage stamp, the Penny Black, is released.
• Samuel Morse patents the telegraph.
