Description
Currently these are averaged across deciles, which results in some reforms having different directional impacts between relative and absolute, e.g. this.
Let's instead compute these as total aggregates, i.e.
- Absolute = total change to net income in £/$ divided by number of households
- Relative = absolute / total baseline net income
Then we should change the client to read:
- [Reform] would {increase, decrease} total net income by $x per household
- [Reform] would {increase, decrease} total net income by y%

Research direction
Start by tracing the decileAverageImpact calculation in the API and the corresponding client text, using the linked policy example as a reference. Done means absolute and relative impacts use total aggregates rather than decile averages, and the client displays the requested per-household dollar and percentage wording.
