More than 50 years after the term "data science" was coined, there continues to be a debate about its precise definition and what a career in data science entails.
This debate too often consists of opinions, personal and professional biases, and anecdotal evidence. Surprisingly, very rarely is it backed up by actual data or data with a sample size that is big enough (a data science question in itself).
RJMetrics has just released a first comprehensive report on the state of data science. It is based on millions of LinkedIn profiles and provides definitive answers to many of the questions posed by data science practitioners and aspiring data scientists alike.
Here are a few of the highlights:
- There are roughly 11,400 to 19,400 people who identify themselves as data scientists in the world today.
- 6,300, or 55%, of identified data scientists are located in the United States, with the United Kingdom, India, France, Canada, the Netherlands, Germany, Spain, Australia and Israel closing out the top 10.
- The number of data scientists has doubled over the last 4 years.
- Over 79% of data scientists that list their education have earned a graduate degree, and 38% have earned a PhD.
- The majority of data scientists come from STEM graduate-level backgrounds, with Computer Science, Statistics, Mathematics and Physics leading the way. However, there are significant differences at the Master’s and PhD levels.
- The top five skills listed by data scientists are: data analysis, R, Python, data mining, and machine learning.
