Every decade has its hottest job opportunities. During the 1980s and early 1990s, people were in a rush to apply for investment banking jobs. Then in the late 1990s and early 2000s, it became clear that the internet will soon change the world. And a lot of tech-savvy graduates started specializing in software and web development. Today, it’s ever clear that big data machine learning and artificial intelligence will become and in some ways already are the key success factor that will determine whether businesses will be successful or not in the coming years. That said, it comes as no surprise that the hottest opportunity on the job market in 2017 and 2018 is the data scientist profession. The power data scientist articulates advanced and terrifies off people. But perhaps dissecting the typical profile of these professionals will help us show you they are in fact, human.

And if you are so inclined, you too could embark on the journey of becoming a data scientist. Assuredly, at a glimpse, the title data scientist has an air of composure and appearance, but the data begs to differ, crunching the numbers, it becomes obvious that there are trades data scientists share. To obtain a better knowledge of the typical data scientist profile, our team collected information from the LinkedIn profiles of 1001 data scientists specialists. Unlike previous publications, the primary source of data we used, we’re not job ads, which skew findings towards the employer’s point of view. Instead, we relied on information posted by data scientists themselves. The underlying assumption was that one’s LinkedIn profile is a good estimator of their resume. Then we proceeded to assign company and country quotas to limit bias. The cohort was divided into two groups depending on whether a person was employed by a fortune 500 company or not. In addition, the sample involves data scientists working in the US around 40% of our sample, UK, another 30%, India, accounting for 15% and other countries.

The remaining 15% convenience sampling was used due to limited data accessibility. Once we gathered the numbers, we stumbled upon several interesting findings. The typical data scientist profile is a male who speaks a foreign language with four and a half years of overall work experience. This is a median. He works with our indoor Python and holds a masters and or a Ph.D. degree. Just from the simple overview, we get several noteworthy insights. You can be promoted to data scientist fairly quickly, assuming you graduate your masters before turning 25 or your Ph.D. before 30. It conservative estimate is that by the age of 30 to 35, you can expect to be a professional whose job title reads data scientist. Another interesting finding is that is in Python are on the rise. Previous research shows that two programming languages are increasing in popularity in the data science world and that this is happening at the expense of other languages like Java and C c++. The results observed here corroborate this trend, you need to start learning R and Python if you want to become a data scientist in 2018. In addition, we can conclude that this is a job for highly educated people. Of course, there is the occasional exception to the rule. But three out of four data scientists in the cohort held a masters or a Ph.D. degree. Indeed, data science is a profession that requires a strong academic background. However, given that this is a relatively new field, it comes as no surprise that the data scientists included in the study have heterogeneous academic profiles degrees such as computer science, statistics and mathematics, economics and social sciences data science and analysis, natural sciences and engineering dominated the field with 91% of the professionals have graduated from one of them. The conclusion, universities, and colleges still struggled to meet the growing job market demand for data scientists and companies hire intelligent candidates with different backgrounds. These people have probably been able to acquire the skills employers look for on their own through self-preparation, or through extensive on the job training. How can oneself prepare to become a data scientist? Some of the most popular online courses teach people how to run machine learning algorithms in Python and are and how to deal with databases. E-learning is positively a resource many data scientists take advantage of. The study shows that 40% of data scientists have posted an online certificate on their LinkedIn profile. And the average number of certificates per person is three. Is this a job for people coming from top tier universities only? It isn’t actually, yes, more than 28% of data scientists came from top tier universities, top 50 in The Times Higher Education World University ranking.

But a significant portion of professionals more than 25% graduated from schools that were not even included in the ranking or were ranked after the thousandth place. So if you’re an aspiring data scientist who is about to graduate or has graduated from a non-target school, you shouldn’t worry too much, you still have significant chances of landing the job. Self-preparation looks like the key to success in the current invite government, which are the industry’s hiring the most data scientists, it has got to be the tech IT industry, right? Indeed it is. technology corporations are seen as a figure of discovery. Moreover, data science is essential for such firms, as it helps them read online behavior patterns, understand customers desires, analyze, online search, improve product offering and so on. Industrial firms come in second, hiring more than 37% of data scientists while the financial 15% and healthcare 5% sectors come in as third and fourth, respectively. It gets even more interesting if we detect this data by country, we begin to see that the financial industry in the UK employs a significantly higher percentage of data scientists are about 20% with respect to the other clusters.

And it makes sense London is known as Europe’s financial capital and play financial trading and brokerage firms reside there. The business market in India on the other hand essentially exercises data scientists in the tech IT sector. This is coherent with the country status as the world’s prime destination for outsourcing of tech and IT services. Our conclusion? Hopefully, this research paints a clearer picture for you and helps you understand the core skills and qualifications people currently employed as data scientists have. In addition, the country why segmentation is invaluable as geographical differences pertain and so does the skill set required to land the job.

This is an example post, originally published as part of Blogging University. Enroll in one of our ten programs, and start your blog right.

You’re going to publish a post today. Don’t worry about how your blog looks. Don’t worry if you haven’t given it a name yet, or you’re feeling overwhelmed. Just click the “New Post” button, and tell us why you’re here.

Why do this?

• Because it gives new readers context. What are you about? Why should they read your blog?
• Because it will help you focus you own ideas about your blog and what you’d like to do with it.

The post can be short or long, a personal intro to your life or a bloggy mission statement, a manifesto for the future or a simple outline of your the types of things you hope to publish.

To help you get started, here are a few questions:

• Why are you blogging publicly, rather than keeping a personal journal?
• What topics do you think you’ll write about?
• Who would you love to connect with via your blog?
• If you blog successfully throughout the next year, what would you hope to have accomplished?

You’re not locked into any of this; one of the wonderful things about blogs is how they constantly evolve as we learn, grow, and interact with one another — but it’s good to know where and why you started, and articulating your goals may just give you a few other post ideas.

Can’t think how to get started? Just write the first thing that pops into your head. Anne Lamott, author of a book on writing we love, says that you need to give yourself permission to write a “crappy first draft”. Anne makes a great point — just start writing, and worry about editing it later.

When you’re ready to publish, give your post three to five tags that describe your blog’s focus — writing, photography, fiction, parenting, food, cars, movies, sports, whatever. These tags will help others who care about your topics find you in the Reader. Make sure one of the tags is “zerotohero,” so other new bloggers can find you, too.
