## How this answer was calculated

The headline compares the first and last observations shown. Overall change is the last index value minus the first and is reported in index points; relative change is (last ÷ first − 1) × 100. Intermediate observations remain visible in the chart and exact values. This is descriptive and does not identify causes.
