There was a significant difference between the locations in which persons missing in farmland and urban areas were found, and in addition there was a significant gender difference for persons missing in farmland.

The following additional information was provided with regard to five incidents for which the location was reported as ‘open ground’:

"Hit a natural barrier and sat down, stuck in dense undergrowth, asleep on a park bench, found in thick bushes and found in a patch of overgrown nettles and grass."
