    What is it?

                    Actuaries are people whose job is to use data in a way that can best plan for financial risk relating to insurance and the financing profession. Anything that would potentially be paid out, be it through an insurance claim or via a pension is evaluated through concrete data. Companies will experience mortality, retirement, disability and other common claims and so the appointed actuaries determine these risks and uncertainties. Actuarial sciences are also applied to cases where life insurance is being assessed, to create a fair rate for the beneficiary based on health of the subject, as well as habits. It’s even used like data science to assess risky ventures a company could make in their investments or in what insurance policies they choose to hold.

    When did it start?

                    Insurance itself came around in the late 17th century, when risk assessment became easier for people to understand and a lot more scientifically based. The very first cases of mortality tables were released by actuarial scientists at the end of the century, and served to divide the population into categories based on lifestyle and circumstances of said lifestyle. This made it easier for insurance brokers of the era to figure out how much risk they were taking with any new policy made. For example, you wouldn’t give the best life insurance rate to a man who was a known alcoholic and got into a lot of bar fights, because his risk of kidney failure or getting himself killed are actually quite high.

    How it applies to business

                    Actuarial services relate to business primarily through insurance, and actuaries themselves typically work with insurance firms where their skills are put to the most effective use. There, they will apply an analysis of factors related to life expectancy and create mortality tables that measure the predictability of a scenario happening, and give their unique proposals to brokers. Not just for mortality and life insurance, but they also determine scenarios for other kinds of insurance, such as property and liability, even health and dental.

                    When applied to finance, it works a lot like data science does in business, but there’s a few key differences. They can apply analysis to predict the outcome of an investment, and are thus a strong presence in investment banks. A good actuary in the financial world will have acute knowledge of industries and potential investments.

    How it differs from data science

                    As mentioned previously, actuary services are very similar to data science used in businesses. Both assess risk, value, and determine outcome and reward by taking those risks into account. However, actuaries work with more concrete data and almost exclusively for insurance or investment related numbers, typically having more accurate numbers based off of existing results rather than educated guesswork. Data scientists apply their work to a broader number of subjects, both structured and unstructured, and are not just limited to insurance. However, their numbers are used as a guideline for success rather than an assurance.

                    Actuaries will often use existing algorithms and place a conclusive number on their work, whereas data scientists are the ones to develop new software and algorithms, and their guesswork is geared towards variables that can’t have a fully determined outcome but aim to be more progressive. One of the biggest differences between the two professions though is that actuaries have an in-depth grasp of the financials and economic issues of the businesses they work with to create financial statements, while data scientists will not often use their skills to create statements.
