Great, thx for your reply!

Why is there no longitudinal data of global life satisfaction and global happiness here: https://ourworldindata.org/happiness-and-life-satisfaction (there is lots of country-specific longitudinal data)?
Could you add a feature that let's the user combine several countries into one graph (so you could compare e.g. life satisfaction of Scandinavian countries over time with life satisfaction of South American countries over time)?

Hi Eric, whenever I try to go to the Wiki I get a screen message saying: 403: Forbidden, this page cannot be displayed. I checked the troubleshooting page, but it seems to contain only advice for the person who manages the wiki, not for visitors (file permissions etc.): https://www.hostgator.com/help/article/403-forbidden-or-no-permission-to-access?utm_source=externalerror&utm_medium=hgsuspage&utm_campaign=client403 Do you have any advice? I'm based in Switzerland, both chrome and firefox didn't work (on a mac).
