Yeah, the source for the flu info is linked above, and "all cause mortality" varies from country to country. I don't know if any mainstream outlet that has analyzed/announced worldwide figures for 2020 yet, but I'll keep looking. In the meantime you can search up each country's official take on it. New Zealand's deaths were significantly down in 2020, for example. https://www.thelancet.com/pdfs/journals/lancet/PIIS0140-6736(20)32647-7.pdf

I'll do a post on it if/when I find good worldwide data that includes 2020. Probably won't hear too much about it on CNN!
