A survey of an urban district found the following. The total supply of food was enough to meet the population's needs in every month of the last five years, and the food was safe and nutritious.
| Survey finding | Result |
|---|---|
| Households able to reach a food outlet throughout the year | 70% |
| Households able to afford enough food throughout the year | 58% |
A district board plans to increase the amount of food sent to the district. Explain why this change alone would not make the district food secure.
