For the second year, O'Reilly Media conducted an anonymous survey to expose the tools successful data analysts and engineers use, and how those tool choices might relate to their salary. We heard from over 800 respondents who work in and around the data space, and from a variety of industries across 53 countries and 41 U.S. states.

Findings from the survey include:

Average number of tools and median income for all respondents

Distribution of responses by a variety of factors, including age, location, industry, position, and cloud computing

Detailed analysis of tool use, including tool clusters

Correlation of tool usage and salary
