2021 State of Haskell Survey Results

by Taylor Fausak on

The fifth annual State of Haskell Survey closed this week. This post will graph the responses, analyze them, and compare them to previous years. You may be interested in similar posts from 2020, 2019, 2018, and 2017.

This year the survey received fewer responses than previous years. Compared to last year, it’s down by about 15%.
