How many data science professionals did the world need in 2020? An estimated 2.7 million (source: IBM)! And, according to the US Bureau of Labor Statistics, about 11.5 million jobs in data science will be created by 2026.

Organizations of all sizes and across sectors are producing and gathering exponential amounts of data of all types, which will only push up further the demand for services from the data science industry as we head toward 2021. These will be critical in facilitating data-driven decision-making and developing business strategies for companies.

What work does a data scientist do?

In the course of a data science career, a data scientist handles various tasks combining engineering, mathematics, and statistics. Persistence is also critical, especially in the data processing and data cleaning stages. After these initial steps, next come finding patterns and building models geared toward better product prototypes or to better understand product usage and health.

It is no surprise that the work of 🔗data science professionals sees usage in sectors ranging from banking and finance to education and healthcare. And the growing focus on data has led to a boost in demand for related skills such as artificial intelligence and machine learning.

What salaries does a data science professional earn?

Salaries in the data science industry are impressive. The base annual pay for a data scientist in the US is USD 117,345, with a range of USD 86,000–157,000 (source: Glassdoor). Here is a look at estimated salaries for data scientists by experience level (source: ZipRecruiter):

👉Entry level: This refers to recent graduates or to experienced professionals switching over from different domains without relevant work experience. They tend to look more at learning new skills and practicing them, and they therefore receive proper training from their employers. The annual salary is estimated at USD 69,000.

👉Mid-level: The median annual salary is USD 89,000.

👉Experienced: These are professionals with extensive experience in their data science careers. They could earn median annual salaries of USD 1,28,000.

👉Experienced at manager level: The median annual salary could be as high as USD 184,000.

In terms of location, here are the estimated annual salaries:

· In India: INR 708,012 (approx USD 9,507, source: PayScale)

· In the US: USD 96,106 (source: PayScale)

How useful are online courses and certifications?

Those targeting a career in data science or already working in the field would do well to pick up a good data science certification. This is undeniable proof that the holder has skills going beyond the limitations of bookish knowledge.
