| First survey | Second survey | |
|---|---|---|
| Average annual household income (£) | 27,000 | 35,000 |
| Households wanting to eat at a restaurant at least twice a month (%) | 29 | 54 |
Using Table 1, explain why the change in average household income might have contributed to the change in the share of households wanting to eat at a restaurant at least twice a month.
