Greenkeeper bases visitor estimates primarily on Natural England’s annual Monitor of Engagement with the Natural Environment (MENE) survey, an established data source based on greenspace visits made by 45,000 residents aged 16-years+ across England. Our model has been built to then combine this data with exact location demographics, accessibility and characteristics of the greenspace help us estimate visitor numbers of greenspaces, including those for which no survey data exists. It is important to note however, that this estimated visit number, and therefore estimation of benefits for these visitors, does not include tourists or visitors aged 15 or younger.
