Question
How do data science salaries differ by location, job role, experience level, and year? The story answers with one public dataset and says plainly what that dataset can and cannot show.
Data
Data Science Salaries 2024, a public Kaggle dataset of 6,599 salary records with 11 columns and no missing values (the author’s publication record of 2026-09-10). The story reads the file directly; no database or server is involved.
SQL and schema
Not applicable: the workbook connects to a single CSV; Tableau performs the aggregation.
Method
Built in Tableau from the CSV; four worksheets, one per factor, arranged as a story with captions that stay within what the data supports. No causal claims are made.
Result
- Location. The United States average is $157,073 against India at $41,699, a difference of about $115,000, the largest spread among the four factors the story examines.
- Job role. Average pay varies widely by job title.
- Experience. In this dataset, average salary rises steadily with experience level.
- Time. The average moves from $102,251 in 2020 to $153,124 in 2024. The story adds its own limit: because the number of records differs greatly by year, this trend describes this dataset rather than proving a broader market trend.
