Thank you for addressing the reviewers' comments. I have one non-specific recommendation and one specific one. The non-specific one is that there are a lot of very long sentences. with colons or semi-colons in the middle. They could usefully be changed to full stops to make the text more accessible to the reader. The specific one is that you should have another look at the para on future projections on line 542 to see if the various points you make can be made more clearly / distinctly. The addition of text has made the logic less clear. I would also add a sentence around lines 57-60 re-raising the issue of longitudinal variations in trends as being worthy of future work - that can be shorter than what you have put in the intro.
