| Age | Mean straight line distance travelled (km) | Nearest neighbour index (observed mean distance/expected mean distance) | Moran’s I | No. of presentations |
| 65–74 | 20.8 | 0.19 | 0.42 | 4177 |
| 75–84 | 17.9 | 0.18 | 0.39 | 2518 |
| 85 and older | 13.0 | 0.15 | 0.39 | 2104 |
Note: p-value for Moran’s I is <0.01 for each age cohort.
