$1 in 1636 is equivalent in purchasing power to about $0.86 in 1637.
The dollar had an average **deflation** rate of -14.09% per year since 1636, producing a cumulative price change of -14.09%.
Purchasing power *increased* by 14.09% in 1637 compared to 1636. On average, you would have to spend 14.09% *less* money in 1637 than in 1636 for the same item.
This is an example of **deflation**.

This means that prices in 1637 are 14.09% lower than average prices since 1636, according to the Bureau of Labor Statistics consumer price index.

The 1636 inflation rate was 79.52%. The inflation rate in 1637 was -14.09%. The 1637 inflation rate is lower compared to the average inflation rate of 0.79% per year between 1637 and 2021.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1637 was 12.80. It was 14.90 in the previous year, 1636. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1637 CPI is less than 1636 CPI, negative inflation (also known as deflation) has occurred.
