I surveyed 793 people about writing for work in the first three months of 2016. Among those surveys, I identified 547 people who write primarily in English and write at least two hours per week, excluding time spent writing email. I analyzed that sample.

I recruited people on the withoutbullshit.com blog, on Facebook, and on Twitter, including some people who responded to a promoted tweet on Twitter. Respondents were eligible for a drawing for my book (and as soon as I have one, I’ll send it!) Due to the way I recruited it, this sample is not representative of any group.
