# U.S. inflation rate in 1831: -5.43%

### Inflation in 1831 and Its Effect on Dollar Value

Purchasing power increased by 5.43% in 1831 compared to 1830. On average, you would have to spend 5.43% less money in 1831 than in 1830 for the same item. This is an example of deflation.

In other words, \$1 in 1830 is equivalent in purchasing power to about \$0.95 in 1831.

The 1830 inflation rate was -1.08%. The inflation rate in 1831 was -5.43%. The 1831 inflation rate is lower compared to the average inflation rate of 1.82% per year between 1831 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1831 was 8.70. It was 9.20 in the previous year, 1830. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1831 CPI is less than 1830 CPI, negative inflation (also known as deflation) has occurred.

### Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1830 would be equivalent to £1.10 in 1831, an absolute change of £0.10 and a cumulative change of 10.10%.

Compare these numbers to the US's overall absolute change of \$-0.05 and total percent change of -5.43%.

### 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 1830 and 1831.

Compare these values to the overall average of -5.43% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1830 → 1831
Food 0.00 0.00 1.00
Shelter 0.00 0.00 1.00
Energy 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 0.00 0.00 1.00
Medical care services 0.00 0.00 1.00
Medical care commodities 0.00 0.00 1.00

It's important to note that not all categories may be tracked since 1830. This table and visualization use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1830 to 1831

This inflation calculator uses the following inflation rate formula:

CPI in 1831CPI in 1830
×
1830 USD value
=
1831 USD value

Then plug in historical CPI values. The U.S. CPI was 9.2 in the year 1830 and 8.7 in 1831:

8.79.2
×
\$1
=
\$0.95

\$1 in 1830 has the same "purchasing power" or "buying power" as \$0.95 in 1831.

To get the total inflation rate for the 1 years between 1830 and 1831, we use the following formula:

CPI in 1831 - CPI in 1830CPI in 1830
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

8.7 - 9.29.2
×
100
=
-5%

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

• The Republic of Ecuador is founded.,Juan Jose Flores is its first president.
• U.S. Congress authorizes the mass removal of native Indians from the eastern states to the western prairie.
• France begins colonization in Algeria.
• The US Railroad opens its first station in Baltimore

### 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.
