The age-old debate among software developers – tabs versus spaces for code indentation – might seem trivial, a matter of personal preference. However, new data analysis suggests this seemingly minor choice could have a surprising impact on your earning potential. We delve into the findings from the Stack Overflow 2017 Developer Survey to uncover a fascinating correlation: developers who use spaces for indentation tend to Earn More Money.
Spaces For Indentation Could Lead to a Bigger Paycheck
The 2017 Stack Overflow Developer Survey collected data from over 28,000 professional developers who weighed in on the tabs vs. spaces question. Interestingly, the survey revealed that 41.8% prefer spaces, slightly edging out the 40.7% who use tabs (with 17.5% using both). But the real eye-opener came when salaries were factored in.
Analyzing the salary data of over 12,000 respondents, a clear trend emerged. Developers who use spaces for indentation reported significantly higher median salaries compared to their tab-using counterparts, even with similar levels of experience.
The median salary for developers using spaces clocked in at $59,140, while tabs users reported a median of $43,750. This striking difference prompts the question: is your indentation style linked to your ability to earn more money in the tech world?
Beyond Just Preference: Digging Deeper into the Data
Initially, one might dismiss this as a superficial correlation. Could it be influenced by other factors like geographical location or programming language? For instance, perhaps developers in countries with lower average salaries are more inclined to use tabs.
To investigate this, the data was examined across different countries with a significant number of survey respondents.

While the magnitude of the effect varied across countries – being less pronounced in Europe and more significant in India – the trend persisted. Within each country analyzed, developers favoring spaces still earned more on average. This suggests that geographical location alone isn’t the sole explanation for the salary gap.
Furthermore, different types of developers and programming languages are often associated with varying indentation preferences. For example, DevOps developers are often linked to spaces, while mobile developers might lean towards tabs, potentially due to editor or language conventions.
The survey data was then segmented by developer type and programming language to see if the “spaces earn more” effect held true within these subgroups.

The result remained consistent. Across various developer types and language specializations, the trend of space users earning more prevailed. This robustness was further confirmed when considering factors like education level and company size. Spaces seemed to lead to higher salaries across the board.
Quantifying the Salary Advantage of Spaces
To estimate the isolated impact of indentation style on salary, a linear regression model was employed. This model controlled for various factors potentially influencing income, including:
- Tabs vs. spaces preference
- Country of residence
- Years of programming experience
- Developer type and programming languages
- Level of formal education
- Open source contributions
- Hobby programming
- Company size
The model’s findings were compelling. Using spaces instead of tabs was associated with an estimated 8.6% increase in salary. This is a significant difference, comparable to the salary boost gained from an extra 2.4 years of programming experience.

Correlation vs. Causation: What Does This Mean for Your Income?
While the data reveals a strong correlation, it’s crucial to remember that correlation doesn’t equal causation. This study doesn’t definitively prove that choosing spaces causes you to earn more money. There could be other underlying factors at play that are correlated with both indentation style and salary.
Possible explanations could include:
- Professionalism and Attention to Detail: Perhaps using spaces is perceived as more professional or indicative of greater attention to detail, qualities valued by higher-paying employers.
- Language and Technology Stacks: Developers working with languages and technologies that favor spaces might be in higher demand or work on more lucrative projects.
- Tooling and Best Practices: Spaces might be more prevalent in environments that emphasize coding best practices and utilize advanced tooling, which could also be linked to higher salaries.
Conclusion: Spaces May Be Your Path to Earning More
The Stack Overflow survey data presents a compelling and surprising insight: developers who use spaces for code indentation tend to earn more money. While the exact reasons behind this correlation require further investigation, the robustness of the finding across various demographics and controls is noteworthy.
If you’re a developer looking to maximize your earning potential, this data provides food for thought. While switching to spaces might not be a guaranteed path to a pay raise, it’s a seemingly small change that is correlated with higher salaries within the developer community. Perhaps adopting spaces is a subtle signal of certain desirable traits or skills that are valued in the high-paying segments of the tech industry.
For data enthusiasts and statisticians, the raw survey data is publicly available for further exploration. You can delve deeper into the data and potentially uncover more insights into this intriguing relationship between code indentation and developer income. For now, the data suggests that in the tabs vs. spaces debate, choosing spaces might just be a smart move for your wallet.
