How different technologies are correlated with each other and how developers use these technologies?

This network graph shows which technologies are most highly correlated with each other. The size of each circle corresponds to the proportion of survey respondents who use the technology tool.

Ruby and Rails tend to get used together. Similarly .NET developers look forward to developing on Windows machines and Azure Cloud.

How many developers choose Coding as a hobby?

About 78% of the survey respondents indicated that they code as a hobby. Respondents who have a family and children indicated that they code when at the job. Not a lot of women choose coding as a hobby. Well, I think we have to change the scene by encouraging more women to take part in coding projects outside of work.

How many years since learning to code?

About 30% of the respondents indicated that they have been learning to code for 5–9 years whereas there are people who have been coding for more than 30 years. Isn’t it amazing?

IBM DB2 which is a Relational Database Management System (RDBMS) ranked as the most dreaded database.

MongoDB which is a NoSQL database remains the database technology that developers want to learn the most.

What are the most loved collaboration tools among developers?

About 82% of the developers use GitHub as a collaborative tool whereas more than half use Slack. No wonder Github takes the top spot. It’s one of the widely used collaboration tools that I love to use.

Programming languages with the highest salaries globally

In the USA, Scala takes the top spot as the highest paying programming language followed by Go and Objective C.

What is the average developer salary in 2020?

The Y-axis — Median salary.

The X-axis — Years of programming experience.

From this, we can conclude that DevOps and Site Reliability Engineers make the most as compared to other Developers.

How often do developers learn new technologies?

Professional developers pick up new tools every few months. Nearly 38% of them seem to learn at least one new technology every year.

What is the educational background of most professional developers?

About 75% of developers finished an undergraduate university degree, and some went on to get a graduate degree. Around 3% of professional developers didn’t go to school after completing a 2-year associate’s degree, and around 17% of developers haven’t earned any university degree at all. This makes me say that you might not need a college degree to be a professional developer.

Majors choosen by professional developers

Computer Science is the most common and highest paying major in the USA. So, choose your major wisely if you are planning to attend university.

How old is the average professional software developer?

Most professional developers are in their late 20s or early 30s.

When it comes to developers in the USA, they tend to be older than developers in other countries, with an average age of nearly 35 years.

Countries where the professional developers come from

Americans also seem to start coding late than other countries and have on average only coded for about 15 years. Well, extra coding experience is always a bonus when it comes to building a rock-solid career in the tech.

Front end developers and full-stack developers generally have an average of 8+ years of coding experience. Managers and executives tend to have 15 years or more of coding experience.

What regions are the survey respondents from?

The breakdown of respondents is as follows:

How many of the respondents were men or women?

Among the respondents that code professionally, almost 92% are men. Only 7.7% of respondents who were professional developers identified as women.

What percentage of developers live with physical or mental differences?

Well, this is interesting to know that quite a few developers are visually impaired or completely blind. This makes me say more people should start coding taking inspiration from people who despite having physical or mental differences are into coding. This is called “Passion”.

What operating system do most developers use?

Nearly 46% of developers use Windows as their main desktop operating system whereas MacOS and Linux take the second and third spot respectively.

How do developers choose their tools?

The most common way to chose a tool is to find out if it has a free trial and just give it a try.

What percentage of developers are full time employed or self-employed?

About 83% of developers are employed full time by companies like FAANG (Where Google, Facebook, Amazon, and Apple all have more than 15,000 employees.). This also includes students who have full-time internships or job offers. Around 10% of developers still prefer working as freelancers or self-employed.
