5 Data Science Portfolios to Aspire for
For three consecutive years, data science has been ranked as the number one job in the U.S. In fact, it has been reported that over the period of next five years, there will be a significant increase in the global demand of data scientists which will create 11.5 million job openings by 2026. 
Indian companies are also largely adopting data analytics and data-based decision making, and as a result, there has been a steady increase in the demand of data scientists over the last year with India contributing to 6% of data science job openings worldwide.  The number of available data science jobs in India increased by 42% in 2015, 52% in 2016, and almost doubled in 2017. Currently, close to 97,000 positions related to analytics and data science are vacant, out of which 97% of openings are full-time while 3% are contractual/part-time roles. 
The Dearth of ‘Qualified’ Data Science Professionals
From healthcare to banking, retail, fashion, and pharma, not just in the technology sector but data science experts are required in every sector.  Data science has important applications across most industries.  For example, your purchase data is used by Amazon to customize your Amazon home page and suggest you relevant products. Similarly, agriculture production data is used by farming companies to define ways for most efficient growth and delivery.
With so much happening in the field of data science, pursuing a career in it is clearly a smart move. In addition to the fact that it is one of the highest paying jobs in India, data is also the pivot point where the entire economy is expected to turn in the coming years. 
However, as many as 97000 positions in data science related field are vacant in the dearth of qualified talent. In order to break into these high paying, in-demand job roles, you need to have an advanced degree in a related field. While the most common field of study for data scientists includes Mathematics and Statistics (32%) followed by Computer Science (19%) and Engineering (16%), people with Bachelor’s degree in Computer science, Social sciences, Physical sciences, and Statistics are also preferred for the role. 
It is important to note that a majority of data scientists are highly educated with 88% having at least a Master’s degree and 46% have PhDs as per the reports in KDnuggets, a leading site on Big Data.
While a Ph.D. or masters degree may not be the norm, but truth is that most aspiring data scientists undertake at least one or more online courses in a related field. A degree in any data science courses will give you the skills you need to process and analyze big data. Therefore, it is a good idea to enroll yourself in an online course in the field of Hadoop, Big Data, Machine Learning, Data Science, Mathematics, Astrophysics or any other related field. The skills you have learned during your degree program will enable you to easily transition to data science.
