This document discusses trends in open-source data science adoption. It notes that the early majority of data science learners on platforms like DataCamp are professionals under 35 years old, mostly male, from countries with higher GDP, and in North America and Europe. These learners want to build models and solve problems, but first need basic skills training. Their focus on easier syntax and higher-level interfaces is driving the growth of tools like the dplyr package over data.table in R and increasing popularity of Python overall for data science.
