I'm struggling to understand how the overall Overshoot Day could be August 2 when looking at the by-country breakdown, I don't see any really significantly populous countries having a Country Overshoot Day past August 2.

It seems to me that the population-weighted average of the country dates should be the global date, right?

Edit: Found it. I looked for the underlying data and several populous countries have a Country Overshoot Day of "none", meaning they could drag the overall average quite a bit later but are not shown in the infographic.
