As a result,\u00a0<a href=\"https:\/\/365datascience.com\/data-science-rising-career\/\" target=\"_blank\" rel=\"noopener noreferrer\">the position of data scientist has emerged as a truly attractive career path option<\/a>\u00a0with an abundance of rewarding job opportunities.<\/p>\n<p>So, to help you stay at the forefront, we\u2019ve conducted an\u00a0<a href=\"https:\/\/365datascience.com\/wp-content\/uploads\/2020\/06\/Data-Science-Jobs-Report-2020.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">in-depth study on job offers in the field of data science.<\/a><\/p>\n<p>And in this article, we\u2019ll share our insights based on 1,170 data scientist job descriptions in the USA. We\u2019ve extracted valuable information about the companies offering the position, the required educational credentials, and sought-after work experience, as well as the desired skills and techniques involved.<\/p>\n<p>Let\u2019s explore the intriguing findings together, shall we?<\/p>\n<p>\u00a0<\/p>\n<h3>Data Scientist Job Descriptions 2020<\/h3>\n<p>\u00a0<\/p>\n<p><strong>What companies were targeted in the research?<\/strong><\/p>\n<p>The 1,170 data scientist positions in our study were posted by\u00a0<strong>357 unique companies<\/strong>. This is a positive sign, as:<\/p>\n<ul>\n<li>The presence of many different companies means the data is more likely to be a random sample of the market and therefore not biased towards the requirements or needs of a single or few companies.<\/li>\n<li>This also shows that the website is an active and popular job openings aggregator.<\/li>\n<\/ul>\n<p>That being said, let\u2019s take a look at the distribution of offers against the size of the company making the offer. Here\u2019s a chart of the number of openings posted by companies with their respective number of employees:<\/p>\n<p><img class=\"aligncenter size-large\" src=\"https:\/\/365datascience.com\/wp-content\/uploads\/2020\/05\/data-scientist-job-descriptions-number-of-offers-768x432.jpg\" width=\"90%\"><\/p>\n<p>It\u2019s easy to see that the majority of job offers come from very big companies, with more than 10,000 employees. This could significantly\u00a0<a href=\"https:\/\/365datascience.com\/measuring-asymmetry-skewness\/\" target=\"_blank\" rel=\"noopener noreferrer\">skew our data\u00a0<\/a>towards the necessities of big corporations. However, looking beyond that, 823 of the total 1,170 job offers were posted by companies that\u00a0<strong>didn\u2019t actually have<\/strong>\u00a0a profile on the website. Therefore, their size hasn\u2019t been determined and is not present in the chart.<\/p>\n<p>With that in mind, we can assume that\u00a0<a href=\"https:\/\/365datascience.com\/data-science-consulting-companies\/\" target=\"_blank\" rel=\"noopener noreferrer\">bigger companies tend to register on more employment websites<\/a>, while their\u00a0<a href=\"https:\/\/365datascience.com\/best-startups-data-science\/\" target=\"_blank\" rel=\"noopener noreferrer\">smaller counterparts<\/a>\u00a0do not engage as much. So, these 823 offers could have been made by companies small enough to not register.<\/p>\n<p>\u00a0<\/p>\n<h3>But what about the offers themselves? Let\u2019s analyze this!<\/h3>\n<p>\u00a0<\/p>\n<p><strong>Data scientist job descriptions: location<\/strong><\/p>\n<p>The data scientist job descriptions we studied originated from\u00a0<a href=\"https:\/\/en.wikipedia.org\/wiki\/List_of_states_and_territories_of_the_United_States\" target=\"_blank\" rel=\"noopener noreferrer\">38 states in the U.S.<\/a>\u00a0Here are the top 12: California, Virginia, Washington, New York, Massachusetts, Maryland, Texas, Colorado, Michigan, Ohio, New Jersey, and Florida.<\/p>\n<p><img class=\"aligncenter size-large\" src=\"https:\/\/365datascience.com\/wp-content\/uploads\/2020\/05\/data-scientist-job-descriptions-location-768x432.jpg\" width=\"90%\"><\/p>\n<p>And here are the same states highlighted on a map:<\/p>\n<p><img class=\"aligncenter size-large\" src=\"https:\/\/365datascience.com\/wp-content\/uploads\/2020\/05\/data-scientist-job-descriptions-locations-map-768x432.jpg\" width=\"90%\"><\/p>\n<p>Now that you have a good idea about the top states by number of offers, let\u2019s move on to the job requirements.<\/p>\n<p><strong>What is the required education in data scientist job descriptions in 2020?<\/strong><\/p>\n<p>When it comes to education,\u00a0<strong>544<\/strong>\u00a0job offers stated that they require at least a\u00a0<strong>Bachelor\u2019s<\/strong>\u00a0degree,\u00a0<strong>367<\/strong>\u00a0\u2013 a\u00a0<strong>Master\u2019s<\/strong>\u00a0and\u00a0<strong>50<\/strong>\u00a0were looking for a\u00a0<strong>Ph.D.<\/strong> While at the same time in 209 job offers, the level of education was not stated.<\/p>\n<p>As for the\u00a0<a href=\"https:\/\/365datascience.com\/best-degrees-data-scientist\/\" target=\"_blank\" rel=\"noopener noreferrer\">preferred fields of study<\/a>, here are the results.

However, there are two very important factors to consider here:<\/p>\n<ul>\n<li>The sample size is not large, especially for the Ph.D.<\/li>\n<li>This data applies to candidates with a degree that is the minimum requirement. In fact, there were no job postings that did not require university education. As in any other industry, holding a Ph.D. lowers the minimum required experience. However, not dramatically so, especially having in mind that a Ph.D. takes several years to complete.<\/li>\n<\/ul>\n<p>So, let\u2019s look at how the company size affects the experience required.<\/p>\n<p><img class=\"aligncenter size-large\" src=\"https:\/\/365datascience.com\/wp-content\/uploads\/2020\/05\/data-scientist-job-descriptions-required-experience-768x432.jpg\" width=\"90%\"><\/p>\n<p>For this analysis, we have grouped the companies into 5 categories:\u00a0<strong>small<\/strong>\u00a0(1 \u2013 100 employees),\u00a0<strong>medium<\/strong>\u00a0(100 \u2013 1,000 employees),\u00a0<strong>big<\/strong>\u00a0(1,000 \u2013 10,000 employees),\u00a0<strong>sizeable<\/strong>\u00a0(10,000+ employees), and those with\u00a0<strong>No size data<\/strong>. It is very important to remember that the sample size here is rather small.<\/p>\n<p>Quite surprisingly, it looks like the smallest companies have the highest requirements for experience. Apart from the sample limitation, we can assume that smaller companies have a limited number of employees. So, to expand and become successful, it needs more experienced professionals. The sizeable companies, in contrast, may not necessarily need an experienced individual but someone they can train to become a useful tool for the company in the future.<\/p>\n<p><strong>And we\u2019ve arrived at the last piece of analysis \u2013 what companies of different sizes require as a level of education.<\/strong><\/p>\n<p><img class=\"aligncenter size-large\" src=\"https:\/\/365datascience.com\/wp-content\/uploads\/2020\/05\/data-scientist-job-descriptions-companies-different-sizes-level-education-768x432.jpg\" width=\"90%\"><\/p>\n<p>Due to the small samples, we have decided to summarize the data in a table, rather than a graph. Smaller companies don\u2019t really look for Ph.D.s and prefer Master\u2019s degree holders. At the other end of the spectrum, the bigger companies have somewhat more balanced requirements with an approximately equal number of positions asking for either a Bachelor\u2019s or a Master\u2019s degree.<\/p>\n<p><a href=\"https:\/\/365datascience.com\/data-scientist-job-descriptions\/\" target=\"_blank\" rel=\"noopener noreferrer\">Original<\/a>.
