Definition of Base Year
A Base Year is the initial year selected as a reference point for measuring changes in an economic or financial index, like lifting a massive weight so you can gauge your future gains at the gym. This year is assigned a value of 100, and subsequent years are rated against it. By periodically updating the base year, analysts ensure that the index remains relevant and reflects the current economic environment without requiring a crystal ball. 🧙♂️✨

- Companies often choose recent years as a base year to assess growth, say from 2020 to 2023, to analyze the impact of pandemics on sales, trends, and whether impulse buying of toilet paper was an anomaly or the new norm. 📈🚽
- Economic Indicator: A statistic about economic activity used to gauge the condition of the economy. Think of it as your financial health scoreboard.
