This map series breaks down 2016 National Park Service visitor data, with park size included for context. For the camping metrics, I compared every park against the average across all parks which offered that specific type of access (tent, RV, backcountry). This doesn’t account for total number of available tent and RV campsites however, which might be interesting.
I used abstract circles for park size since there is such a large disparity in area between the largest and smallest units (0.3 acres vs 2 million acres). Using true shape and area would leave most parks invisible at this scale. Maybe unsurprisingly, the most time consuming part was cleaning up the data. The visitor data was in one table while park size was in another. Names for each unit often didn’t match across the two tables, due to abbreviations. Visitor data is also omitted from many of the small or remote parks or is in some cases is combined across multiple units.
This was one of the first complete maps I ever made using ArcGIS Pro, as well.
