The results of the latest KDnuggets Poll:
What kind of data science did you do in the past 3 years?
show that
Data Science is mainly a Human Science, with 62% of respondents working ONLY or MOSTLY on data science for humans. Only 14% have worked only or mostly on machine data. The "Other" votes could represent people working on non-human biological data or purely scientific data, like astronomy.
At the same time, about 60% of respondents worked with both human and machine data, casting doubt on the assertion that there are 2 types of data scientists: ones that work with machine data, and ones that work with human data.
The table below gives a regional breakdown for 4 regions with sufficient representation, with 5 "Other" votes excluded.
We note that Europe and Asia have higher machine-data experience than the US, while in Latin America almost all data scientists who responded work with human data.
