Inflation in 2002 and Its Effect on Dollar Value

Purchasing power decreased by 1.58% in 2002 compared to the previous year, 2001. On average, you would have to spend 1.58% more money in 2002 than in 2001 for the same item.

In other words, $100 in 2001 is equivalent in purchasing power to $101.58 in 2002.

The 2001 inflation rate was 2.85%. The inflation rate in 2002 was 1.58%. The 2002 inflation rate is lower compared to the average inflation rate of 2.13% per year between 2002 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 2002 was 179.9. It was 177.1 in the previous year, 2001. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 2001 to 2002 (figures shown are purchasing power equivalents of $100):

San Diego, California experienced the highest rate of inflation during the 1 years between 2001 and 2002 (7.97%).

Houston, Texas experienced the lowest rate of inflation during the 1 years between 2001 and 2002 (0.26%).

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 2001 would be equivalent to £101.67 in 2002, an absolute change of £1.67 and a cumulative change of 1.67%.

In Canada, CA$100.00 in 2001 would be equivalent to CA$103.80 in 2002, an absolute change of CA$3.80 and a cumulative change of 3.80%.

Compare these numbers to the US's overall absolute change of $1.58 and total percent change of 1.58%.

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 2001 and 2002.

Compare these values to the overall average of 1.58% per year:

Category Avg Inflation (%) Total Inflation (%) $100 in 2001 → 2002
Food 1.81 1.81 101.81
Shelter 3.75 3.75 103.75
Energy -5.79 -5.79 94.21
Apparel -2.55 -2.55 97.45
New vehicles -1.50 -1.50 98.50
Used cars and trucks -4.22 -4.22 95.78
Transportation services 3.58 3.58 103.58
Medical care services 5.07 5.07 105.07
Medical care commodities 3.56 3.56 103.56

It's important to note that not all categories may be tracked since 2001. This table and visualization use the earliest available data for each category.

How to Calculate Inflation Rate for $100, 2001 to 2002

This inflation calculator uses the following inflation rate formula:

CPI in 2002CPI in 2001
2001 USD value
2002 USD value

Then plug in historical CPI values. The U.S. CPI was 177.1 in the year 2001 and 179.9 in 2002:


$100 in 2001 has the same "purchasing power" or "buying power" as $101.58 in 2002.

To get the total inflation rate for the 1 years between 2001 and 2002, we use the following formula:

CPI in 2002 - CPI in 2001CPI in 2001
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

179.9 - 177.1177.1

Alternate Measurements of Inflation

The above data describe the CPI for all items. Also of note is the Core CPI, which measures inflation for all items except for the more volatile categories of food and energy. Core inflation averaged 2.32% per year between 2001 and 2002 (vs all-CPI inflation of 1.58%), for an inflation total of 2.32%.

When using the core inflation measurement, $100 in 2001 is equivalent in buying power to $102.32 in 2002, a difference of $2.32. Recall that for All Items, the converted amount is $101.58 with a difference of $1.58.

In 2001, core inflation was 2.67%.

Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 1.26% per year between 2001 and 2002, a total inflation amount of 2.32%.

According to the Chained CPI measurement, $100 in 2001 is equal in buying power to $101.26 in 2002, a difference of $1.26 (versus a converted amount of $101.58/change of $1.58 for All Items).

In 2001, chained inflation was 2.26%.
