Updated 3/21/22 with revised links and other more current information/plans.

See??leading to a where the reports will be collected. Start with _How to find reports.pdf in that folder, which includes some links to material not found in the Drive folder itself.

In 2015-16, I recruited a number of fellow hikers with analytic and data presentation skills to do a comprehensive reporting on the 2015 survey, which had 1,286 useful respondents. See, most notably,?

BTW: I'd love other volunteers with data skills I lack -- data presentation skills, particularly in Tableau, analytic skills using tools like R or able to build an online predictive calculator that could predict things like typical miles per day given entered age, prior experience, relative physical fitness, BMI, pack weight etc.?Email me if interested in any of these. It may take some time before I could start to onboard you as I already have a number of volunteers who are moving faster than I can keep up with. An embarrassment of riches from a very helpful community here and even on Facebook.

It was a ton of work and it wasn't clear that repeating the 2015 work each year was worth the effort. And I feared burnout among the volunteers I needed to present the data well.

I decided to efficiently use my own resources, and to readily recruit others with analytic skills, by waiting until I could pool results across multiple years. That would allow us to look both at problems that were the same year-to-year and how some problems differed between years.

There are some reports from 2016 thru 2019, but they are minimal compared to the 2015 reporting. There are also a number of 2014 reports in the Drive folder.

So I am working now on pooling and cleaning the data from 2014 to 2021. There are 6,969 usable responses to many of the questions.

Individual multi-year graphics will start to come out often. They will be found in the folder above.

We are giving priority to actionable data helping 2022 hikers.

Serious multi-factor analysis of pooled responses probably won't come out until the Summer (probably too late for the 2022 hiking season) as the data assembly work is surprisingly tedious because the 2014 and 2015 questions were partly reframed for 2016 and later years. I don't give the data to folks with analytic skills until it is reasonably complete for the issue we are trying to address.?

There is an academic group of Wilderness Medical Society members out of UCF Fresno, led by Dr. Susanne Spano, have published peer-reviewed reports on the earliest (2014) version of the survey and I look forward to seeing their analysis of the pooled data, though publishing delays will probably push them until 2023 at best.?
