Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1905 would be equivalent to £1.00 in 1904, an absolute change of £0.00 and a cumulative change of 0.00%.

Compare these numbers to the US's overall absolute change of $0.01 and total percent change of 1.14%.

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 1905 and 1904.

Compare these values to the overall average of -1.12% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $1 in 1904 → 1905 |
---|---|---|---|

Food and beverages | 0.00 | 0.00 | 1.00 |

Housing | 0.00 | 0.00 | 1.00 |

Apparel | 0.00 | 0.00 | 1.00 |

Transportation | 0.00 | 0.00 | 1.00 |

For all these visualizations, it's important to note that not all categories may have been tracked since 1905. This table and charts use the earliest available data for each category.

Our calculations use the following inflation rate formula to calculate the change in value between 1904 and 1905:

$1 in 1905 has the same "purchasing power" or "buying power" as $1.01 in 1904.

To get the total inflation rate for the 1 years between 1904 and 1905, we use the following formula:

CPI in 1904 - CPI in 1905CPI in 1905

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

- The Industrial Workers of the World is formed. It is an American anarcho-syndicalist union.
- Bloody Sunday in Russia: troops fire and kill protesters, mostly workers, marching to the Winter Palace in order to hand a petition to the Tsar.
- Potemkin's arrival at Odessa leads to sailors joining civilians in the '1905 Revolution’.

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.
