Are you looking for ways to earn more money as a software developer? The tech world is constantly evolving, and understanding what factors can influence your earning potential is crucial. While technical skills and experience are undoubtedly key, could something as seemingly trivial as your code indentation style play a role? Surprisingly, data suggests there might be a correlation between how you format your code and your salary.
A fascinating analysis from the Stack Overflow 2017 Developer Survey revealed an unexpected trend: developers who use spaces for code indentation tend to earn more than those who use tabs. This sparked a debate and raised questions about whether coding style could be linked to financial success in the tech industry. Let’s delve into the data and explore this intriguing relationship.
The survey analyzed responses from over 28,000 professional developers, and of those who provided salary information, a clear pattern emerged. The median salary for developers using spaces was $59,140, significantly higher than the $43,750 median salary for developers using tabs. This is a substantial difference, prompting us to investigate further.
Initially, one might assume this is simply a coincidence or influenced by other factors. Perhaps developers in higher-paying countries prefer spaces, or certain programming languages associated with higher salaries favor spaces over tabs. To address these concerns, the analysis examined the data across different countries.

Even when considering individual countries, the trend persisted. While the salary gap varied in size, developers using spaces earned more than their tabs-using counterparts in multiple countries. This suggests the initial observation isn’t solely due to geographical salary differences.
Furthermore, the analysis explored various developer subgroups based on their roles and programming languages. Different developer types and languages might have different coding conventions, potentially influencing indentation preferences. For example, DevOps developers might lean towards spaces, while mobile developers might prefer tabs due to historical editor defaults or language conventions.

Intriguingly, the salary advantage for spaces users held true across all developer types examined, including web developers, mobile developers, and others. This consistent pattern strengthens the argument that the tabs vs. spaces choice might be linked to earning potential, independent of developer specialization. Further investigation into other potential confounding factors, such as education level and company size, also yielded similar results – spaces users consistently demonstrated higher salaries within each group.
To quantify the impact of indentation style while controlling for other salary-influencing factors, a linear regression model was employed. This model considered variables like country, years of experience, developer type, programming languages, education level, open-source contributions, hobby programming, and company size, alongside the choice of tabs or spaces.

The regression analysis estimated that using spaces instead of tabs is associated with an 8.6% higher salary. To put this into perspective, this salary difference is comparable to having an extra 2.4 years of programming experience. While correlation doesn’t equal causation, this robust statistical relationship is compelling and warrants further consideration.
Conclusion: What Does This Mean for Your Earning Potential?
The Stack Overflow survey data reveals a fascinating correlation: developers who use spaces for indentation tend to earn more money. While switching to spaces might not directly guarantee a salary increase, this finding opens up interesting questions about coding habits and career success.
It’s important to remember that this is a correlation, not proof that spaces cause higher salaries. There could be underlying factors at play. Perhaps developers who are more meticulous about code style, including using spaces, also tend to be more detail-oriented and professional in other aspects of their work, leading to better career opportunities and higher pay. Alternatively, teams and companies that prioritize code quality and standards might also favor spaces and offer higher compensation.
For developers looking to maximize their earning potential, the takeaway isn’t necessarily to immediately switch to spaces if you prefer tabs. Instead, consider this data as an intriguing insight into the subtle factors that might be associated with higher income in the tech industry. Focusing on writing clean, consistent, and professional code, being aware of industry best practices, and continuously improving your skills are all likely to contribute to career advancement and, ultimately, earning more money.
If you are interested in exploring this data further, the raw survey data is publicly available. Analyzing it yourself could uncover more insights into the relationship between coding practices and developer salaries, and potentially reveal other unexpected factors that influence how much you can earn in the tech world.
