The location of a place can be described in many ways - the address, in reference to what it's near, or just by a name. Statisticians use addresses in many ways, including:
- For sampling in household based surveys;
- For summarising information that has a geographical dimension, ranging from the Census to small surveys; and
- For describing personal and freight movements in transport surveys.
The level of accuracy required in the address can vary depending on its planned use. An address that has adequate information for a letter to be delivered, for example, may not necessarily have enough detail to enable an ambulance to arrive at the correct destination in reasonable time. For some statistical work it may be sufficient that just the suburb is correct.
