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 1930 and 1928.

Compare these values to the overall average of -1.18% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $1 in 1928 → 1930 |
---|---|---|---|

Food and beverages | 0.00 | 0.00 | 1.00 |

Housing | 0.00 | 0.00 | 1.00 |

$1 in 1930 has the same "purchasing power" or "buying power" as $1.02 in 1928.

To get the total inflation rate for the 2 years between 1928 and 1930, we use the following formula:

CPI in 1928 - CPI in 1930CPI in 1930

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

- Mohandas Gandhi protests British salt tax by a 200-mile-long walk.
- Clyde Tombaugh discovers Pluto.
- Lawrence Hyland discovers the first radar by accident.
- Roald Amundsen's leads the first expedition to reach the South Pole.
- American explorer Hiram Bingham discovers Machu Picchu.

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (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.
