Changeoffacts

Changeoffacts is a term used in data communication and information design to describe a practice that foregrounds change in indicators over time rather than presenting single-endpoint values. The approach emphasizes trends, rates of change, and context, aiming to help audiences interpret dynamics, momentum, and potential futures. It is used in journalism, policy briefs, and dashboards to make complex data more intuitive.

The term is not a formal standard but emerged in discussions among data practitioners in the 2010s, and has been applied across sectors including economics, public health, and climate reporting to illustrate trajectories rather than static snapshots.

Its methodology relies on time-series data, baselines, and comparison frames. Common techniques include displaying trend lines, change boxes showing percentage or percentage-point shifts, and annotations that explain the drivers of change. Uncertainty and sampling variation are typically communicated with confidence intervals or scenario ranges.

Proponents argue the method improves comprehension of policy impact and risk, while critics warn that changing values can obscure absolute levels and baselines may be selected to highlight a desired narrative. Best practices emphasize clear baselines, explicit timeframes, and transparent uncertainty.
