Data Science vs Actuarial Science: Which Career Path Should You Choose?

What is Data Science?

Data science is the interdisciplinary field of using scientific methods, algorithms, and systems to extract knowledge and insights from structured and unstructured data. Data scientists apply various techniques such as machine learning, data mining, natural language processing, and visualization to analyze data and generate value for businesses and organizations. Data scientists can work in a wide range of industries, such as technology, healthcare, finance, education, and entertainment.


What is Actuarial Science?

Actuarial science is the discipline of using mathematical and statistical methods to assess and manage risk, especially in the context of insurance and finance. Actuaries use data and models to calculate the probability and financial impact of uncertain events, such as accidents, illnesses, deaths, and natural disasters. Actuaries also design and evaluate insurance products, pension plans, and investment strategies. Actuaries typically work in the insurance industry, but they can also find employment in other sectors, such as banking, consulting, and government.

How to Become a Data Scientist?

There is no standard or formal path to becoming a data scientist. However, most data scientists have a strong background in mathematics, statistics, and computer science. A bachelor’s degree in one of these fields, or a related discipline, is usually the minimum requirement for entry-level data science positions. However, many employers prefer candidates who have a master’s or doctoral degree in data science or a related field, as they demonstrate advanced skills and knowledge in data analysis and modeling.
In addition to formal education, data scientists also need to have practical experience in working with data and tools. Data scientists should be proficient in programming languages such as Python, R, and SQL, and familiar with frameworks and libraries such as TensorFlow, PyTorch, and scikit-learn. Data scientists should also be able to use data visualization tools such as Tableau, Power BI, and Matplotlib, and cloud platforms such as AWS, Azure, and Google Cloud. Moreover, data scientists should have strong communication and business skills, as they need to present and explain their findings and recommendations to stakeholders and clients.

How to Become an Actuary?

To become an actuary, you need to have a bachelor’s degree in actuarial science, mathematics, statistics, or a related field. You also need to pass a series of rigorous exams administered by professional bodies, such as the Society of Actuaries (SOA) or the Casualty Actuarial Society (CAS). These exams cover topics such as probability, financial mathematics, economics, accounting, and risk management. The exams are very challenging and require a lot of preparation and study time. It can take several years to complete all the exams and become a fully qualified actuary.
In addition to passing the exams, actuaries also need to have practical experience in working with data and models. Actuaries should be proficient in programming languages such as Python, R, and SAS, and familiar with software and tools such as Excel, VBA, and MATLAB. Actuaries should also be able to use actuarial software such as Prophet, AXIS, and ResQ, and databases such as SQL and Oracle. Furthermore, actuaries should have strong communication and business skills, as they need to communicate and collaborate with other professionals, such as underwriters, accountants, and regulators.

Actuarial science also involves a lot of paperwork and documentation, as well as compliance and regulation, which can be dull and monotonous.

    What are the Opinions and Experiences of Professionals in Data Science and Actuarial Science?

To get a better perspective and understanding of data science and actuarial science, we have gathered some opinions and experiences from professionals who have worked or are working in both fields. Here are some of their insights and advice:
– “I work as a data scientist in a property & casualty insurance firm. Many of my colleagues are either certified actuaries or taking actuarial exams. In my opinion, both fields offer excellent opportunities. There are certain advantages of data science over actuarial science and vice-versa. For example, data scientists can find employment in a much broader array of industries. Plus, data scientists don’t have to take a bunch of exams to get certified. But actuaries tend to command more respect in financial/insurance/economic settings. In insurance firms, actuaries are treated like royalty. After getting certified as a
a fellow, actuaries can enjoy a lifetime of secure employment with solid compensation. As far as day to day responsibilities, there’s definitely an overlap in the areas of data analysis and statistical modeling. But there are differences as well. For instance, actuaries focus a lot on loss reserving and risk analysis. In contrast, data scientists take on more of the advanced computer programming and data engineering responsibilities. As a result, in many insurance firms you’ll find actuaries and data scientists working side by side. For your specific situation, I recommend you review the topics for the first few exams to determine if it’s something you’d like to pursue. Keep in mind that it’s best to start the actuarial track when you’re young because the exams will typically take 5+ years to complete and will be much more difficult to complete once you have children.” – A data scientist in an insurance firm
– “I am actually a project manager in the data science field, and I have been a project manager in an insurance company, coping with actuaries. Actuaries, in France, seem to earn a better salary. In my company, they worked on data which were often new versions of data they dealt with. So they spent less time on managing and cleaning data. They had to deal with legal issues too. Data scientist had often to deal with poor quality data. Had to convince business people of the use of a better algorithm than the mean. But had more various situations, more interaction with other types of people. Plus, lots of things happen, random forests, big data, it’s fun here. It all depends on what you are looking for. As far as I’m concerned I chose data science, but, I’m no good example as I am 40, still in short term contract, and not that wealthy. If I were you, I’d phone to one of each, and simply talk to them, explaining : I’m a student, hesitating between two career paths. People rarely refuse to talk about themselves. Hope this helps a little.” – A project manager in the data science field
– “I started my career as an actuary, but switched to data science after a few years. I found actuarial science to be too boring and restrictive for my taste. I felt like I was doing the same thing over and over again, with little room for creativity or innovation. I also felt like I was missing out on the exciting developments and opportunities in the data science field. Data science appealed to me because it was more diverse and dynamic, and allowed me to work on more interesting and impactful problems. I also enjoyed learning new skills and tools, and applying them to different domains and contexts. I don’t regret my decision to switch to data science, as I find it more fulfilling and rewarding. However, I do acknowledge that actuarial science has its advantages, such as job security, stability, and respect. I think it ultimately depends on your personality, goals, and preferences. You should choose the field that makes you happy and satisfied.” – A former actuary turned data scientist

Conclusion: Data Science vs Actuarial Science
