Definition of Base Period

A base period is a specific time frame in the past that is used as a benchmark for measuring economic data. This period can be a single year, an average of multiple years, a month, or any other designated time period. The base period serves as a yardstick for comparing subsequent economic activities and data measurements.

Examples

  1. Consumer Price Index (CPI): The Consumer Price Index may use the year 1982-1984 as its base period. All CPI measurements are compared against the average prices of goods and services in this base period.

  2. Gross Domestic Product (GDP): A country’s GDP growth is often measured against a base year. For example, if 2010 is the base year, the GDP for subsequent years is compared to the GDP of 2010 to assess growth or decline.

  3. Stock Market: An index like the S&P 500 may use a specific past date as the base period. All changes in the index are then calculated relative to the value of the index on that base date.

Frequently Asked Questions
