I think I'm misunderstanding the data you're presenting here. When looking through the interactive datasets at population.un.org, they all have year spans of 5 years. This granularity is too high to resolve possible impacts of Covid, even if the 2020 data isn't in there yet. The second source you shared from data.cdc.gov suggests that 2020 deaths are far lower than 2019, I think. At lease, when I trace my data with years on X and all deaths on Y, we see a significant decrease across the years. If data as far up as November is included, then it looks like we're in for a super low death year. I'm assuming I've made some mistake in this. Can you point me toward it?
