Reviewer asked for dataset section within the manuscript
They are not asking you to copy-and-paste the data into the paper in a &quot;dataset section.&quot; They want you to devote more space to explaining what the dataset is and where you got it. Presumably, you did not collect it, so it should be easy to post to the government source.
That said, 7920 data points is tiny and could easily be included in a CSV file (but I digress). If they want you to share it, you could upload it somewhere else and link to it. But since this sounds like a publicly available government dataset, your time would be better spent making sure your preparation of the data is replicable.
