Data Science Market in india will be worth 11 millions jobs by 2026 and the Data Analytics Outsourcing market in India is worth $26 Billions. India is second to the United States in terms of the number of job openings in Data Science. In 2019, 93,500 positions in india by august 2021 data science and analytics were vacant due to the lack of qualified candidates. The top sectors creating the most Data Science jobs are BFSI, Energy, Pharmaceutical, HealthCare, E-commerce, Media, and Retail. Today large companies, medium-sized companies and even startups are willing to recruit the data scientists in India. The main skills are Big Data, Software and User Testing, Mobile Development, Cloud Computing, and Software Engineering Management. The short supply has led to a spike in salaries. Data science professionals with 2-10 years of experience get annual salaries in the range of 10 lakh to 85 lakh, while more experienced people can command annual salaries upwards of 1.6 crore, according to the Talent Trends Report 2021 by Michael Page India, a recruitment Consultants. Experts with more than 15 years of experience can get paid up to 2 crore per year.
