The answer is an unequivocal YES! Data Scientists are in high demand all across the world, and the absence of qualified talent makes data science an extremely rewarding career path. There are three economic factors influencing on job rankings and making Data Science a rising career in 2021

1. Demand : The key reason for the increasing demand for Data Science is that if your competitors employ data-driven decision making while you don’t, they will overtake you and grab your market share. The demand for Data Scientists is crazy and shows no signs of slowing down, which is why they are in the top three job rankings.
2. Supply : Data Scientists are in short supply, and this is due to the fact that the subject of data science is still relatively young in 2021.
3. Evolving field : Data Science is evolving rapidly because of increasing demand of data across the world. New and exciting domains are emerging within this field including Big Data, Artificial Intelligence (AI), Machine Learning (ML), along with some newer technologies such as Blockchain, Edge Computing, Serverless Computing, and others that leverage various practices and techniques from the Data Science industry.

To get started in Data Science without any prior experience follow the below mentioned steps

1. Master your math skills : Math skills include Statistical methods, Probability distribution, Multivariable calculus, Linear Algebra, Hypothesis testing, Statistical Modeling, Data summaries, Descriptive Analytics, Regression analysis, etc
2. Learn some Programming Languages : After you've mastered arithmetic, you can start learning SQL, R, Python, and SAS, which are among the most important programming languages for data scientists.
3. Apply your skillsets in the real world by taking on side projects or internship : You can look for part-time jobs or internships on platforms like Upwork or Fiverr, as well as on social media and job boards.
4. Start as a Data Analyst : Data scientists and data analysts aren't the same thing, although they're both growing in popularity. As a starting employment, data analyst positions can be easier to come by and can serve as an excellent springboard for a data science career.

For many businesses, data science has proven to be a need. Finance, marketing, retail, information technology, and banking are just a few of the businesses that are making the most of their data. Data Scientists are in high demand, and everyone is on the lookout for them. A career as a Data Scientist is open to people from all walks of life.
