We take a look at what the state of play is in the data science industry. You’ll find details about working in the data sector, including the types of roles, salaries, and skills you’ll need to get started.

Data plays an increasingly important role in our lives. Everything from our healthcare to our entertainment is driven by information produced by millions of people worldwide. As we continue to create data in greater volumes and on a larger scale, the data industry grows. We take a look at everything you need to know about the current landscape. 

As we explore this fascinating field, we look at some sectors, jobs, and challenges related to data. We’ll also cover some of the skills you’ll need to enter the industry, as well as how you can get started with a job related to data.  

The global data industry

First, let’s look at what we mean by the term ‘data industry’ and what the current landscape looks like. This will help us get some context as to some of the global trends and what the future might hold: 

What is it? 

The data industry is large, touching on all kinds of different areas and sectors. As such, it can be hard to define the exact parameters of it as one industry. From relatively straightforward tasks like data entry to complex data science, the opportunities and applications related to data are vast and varied. 

That being said, there are a few fields that stand out in particular. These areas will often overlap, but there is generally a high degree of specialization and variety in each. Some examples include: 

We’ll take a look at some of these areas and some relevant data jobs further down. As we’ll see, there are all kinds of roles that fall under these specializations. 

How big is the industry? 

Given the data industry’s scope, it comes to as little surprise that it’s a rapidly growing sector. Some figures suggest that, in 2018, the global big data and business analytics market was valued at $168.8 billion. This figure is expected to grow to around $274.3 billion by 2022, increasing by 13.2%. 

A similar trend is seen in the world of data science. Estimates indicate that the global data science platform market size will be worth around $25.94 billion by 2027. This represents a growth of 26.9% between 2020 and 2027.  

This increase in the value of the industry is also being seen in the demand for data jobs. One report from the UK’s Royal Society found that the need for professionals with specialist and big data skills more than tripled over five years, increasing by 231%. Similarly, in the US, the demand for data scientists increased by 344% between 2013 and 2019. 

However, despite this incredible growth, there is a problem. Many sources report that there is a data skills gap. Across fields like data analytics and data science, there are reports of shortages of skilled professionals. What’s more, employers generally feel that their employees lack data skills, harming productivity

How has the COVID-19 pandemic impacted the data industry? 

However, it’s not all bad news. The coronavirus pandemic has impacted just about every industry in some way. With lockdowns, remote working, and job losses felt around the world, conditions have been difficult. The same is true, in part, for the data industry. 

Data science and big data analytics have played a role in helping us track and understand the virus. As well as monitoring things like health system demands, the ongoing efforts for virus testing, data modeling, and contact tracing have helped turn the tide. 

You’ll have no doubt also seen a lot of data visualization related to the pandemic. Such efforts to present the facts and current situation in an easy-to-understand way have been crucial in keeping people informed. It’s also played a role in convincing people to change their behavior – take ‘flattening the curve’ as an example. 

Despite the successes of the industry, there are still some issues. According to the job site Indeed, in July 2020, US-based data science job listings were 43% below their 2019 levels. Other reports suggest that the global big data analytics growth is expected to be ‘restrained’ in the wake of the pandemic. 

What kinds of jobs are there in the industry?

So, despite the current pandemic-induced climate, there is still a lot to be excited about by the data and analytics industry’s future. If you’re wondering about some of the data-based jobs, you could get involved with, and you’ll find plenty. The field is diverse, with new and exciting roles appearing frequently.
