Whereas the previous questions examined the abundance of physical activities and park benefits by park type, this analysis examined the diversity of activities and benefits. For example, one might hypothesize that parks created for a more narrow set of activities such as sports parks would have less diversity of physical activities and benefits while community parks would exhibit a broader range of activities and benefits. To examine the diversity of activities and benefits by park type, the Shannon diversity index was calculated for each park unit with five or more activities or benefits. The Shannon index (Shannon, 1948) has been widely adopted in the ecology literature as a mathematical measure of species diversity in a community, but it has also been used to quantify and compare the diversity of social values found within bounded landscape areas of interest (Brown & Reed, 2012). The diversity of park activities and benefits was calculated for each park as − pi ln pi where pi, is the proportional abundance of the ith park attribute (activity or benefit) = (ni/N).
