What is the accepted norm for years of alarm data when calculating response times?

The accepted norm for calculating response times in emergency services is typically based on data collected over a three-year period. This time frame allows for a comprehensive understanding of response trends and variations while accounting for any anomalies that may occur in a single year or even over two years. Three years of alarm data provides a more stable average, reflecting both seasonal fluctuations and changes in call volume. It helps fire service organizations establish benchmarks for performance and make informed decisions about staffing and resource allocation. Using this longer timeframe enhances the reliability of the data and ensures that strategic planning is based on solid evidence rather than potentially skewed short-term statistics.
