Inflation in 1788 and Its Effect on Dollar Value
Purchasing power increased by 4.30% in 1788 compared to the previous year, 1787. On average, you would have to spend 4.30% less money in 1788 than in 1787 for the same item. This is an example of deflation.
In other words, $100 in 1787 is equivalent in purchasing power to $95.70 in 1788.
The 1787 inflation rate was -2.11%. The inflation rate in 1788 was -4.30%. The 1788 inflation rate is lower compared to the average inflation rate of 1.47% per year between 1788 and 2018.
Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1788 was 8.9. It was 9.3 in the previous year, 1787. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1788 CPI is less than 1787 CPI, negative inflation (also known as deflation) has occurred.
