Data science is a relatively new field, but it is already getting its time in the spotlight. LinkedIn’s ‘2020 Emerging Jobs Report’ named ‘data scientist’ the third-best job of 2020 among the top 15 emerging jobs in the U.S. Data scientist was also Glassdoor’s third-best job in America for 2022. U.S. News & World Report ranked data science as third-best in the nation among the ‘Best Technology Jobs of 2022’.
According to Wikipedia “Data science is an interdisciplinary field that uses scientific methods, processes, algorithms, and systems to extract knowledge and insights from noisy, structured and unstructured data, and apply knowledge and actionable insights from data across a broad range of application domains. Data science is related to data mining, machine learning, and big data.”
The field of computer science might feel a little overshadowed, with all the attention its offspring, data science, is receiving. Even though data science utilizes many other fields of study, the entire discipline is built upon and processed through the infrastructure of computer science. What those on the inside understand, though, is that the two are part of a symbiotic relationship, with nuances to each that nurture the other.
It is also important to highlight that both these positions are among the highest-paid jobs in the United States. Glassdoor (2022) reported that data scientists nationwide earned an average annual salary of $1,17,212 per year, while computer scientists earned an average annual salary of $1,06,012 per year.
Payscale (2022) found the following percentiles among its data and computer scientist respondents nationwide in June 2022:
The Bureau of Labor Statistics (BLS May 2020) states that the 59,680 data scientists and mathematical science occupation professionals across the country made an average annual salary of $103,930, while the 30,220 computer and information research scientists across the country made an average annual salary of $130,890.
Computer scientists and data scientists have overlapping skills. Each utilizes computational processes. A working understanding of programming languages and algorithms is a must in both fields, but what one does with that understanding is the primary differentiation between the two tracks. Computer science focuses on the “how,” while data science looks at the “why.”
Computer scientists work on the nuts and bolts of computational processes. Usually studying under the school of engineering, CS students architect networks and databases through which data can flow. While much of computer science functions in algorithmic principles, it does so with a specific logical outcome in mind.
In data science, the algorithmic principles are applied to greater areas of uncertainty, often producing probabilistic answers to interdisciplinary questions about the business. Modern data scientists typically have proficiency in computer science, but they can come from mathematical, statistical, or even business backgrounds.
Working on top of what computer science has built, data scientists design unique ways to filter through the massive amounts of data that flow through network systems and then extract actionable insights. Those actionable insights can make a business more efficient and effective; they can widen the world’s understanding of health sciences; and they can even filter back into computer science to create better datasets and customer experiences.
The relationship between computer science and data science is growing increasingly symbiotic, even as each of them evolves. Read on for a side-by-side comparison of the differences and similarities between these two fields of study.

Data science is in its infancy, especially at the undergraduate level, but many programs are available, including:
Computer science is a broad field of study that incorporates all applications of computational processes. Computer scientists may develop applications, write new programming languages, or architect a system that produces and sorts a flow of data.
But for a computer scientist, those processes are often grounded in the symbolic logic of voltages to bits with predictable outcomes, and any probabilistic framings are often built over discrete logic-based elements. This is a nuts and bolts discipline that is building out the infrastructure of the 21st century.
Data science is a relatively new field, the offspring of statistics and computer science. Data scientists may design algorithms, refine data sets, and parse vast swaths of data through mathematical models that yield actionable insights.
To do so, data scientists must take an interdisciplinary approach and embrace uncertainty, incorporating not only computer science, but also statistics, mathematics, business, and communication skills. If computer science is the building of new infrastructure, then data science is the extraction and filtering of the new and valuable global commodity it enables.
