Here's my weekly update from SCB on mortality in Sweden.
Year 2020 has: (1) the highest excess mortality since 1937 (pop. adjusted) (2) the most excess deaths since 1919 (not pop. adjusted) (3) annulled 7 years of all-cause mortality decline (highest ACM since 2013)
1/n
For their part, the Swedish government estimates 4859 as of 30 Nov:
The line representing average expected mortality on my chart is a LOWESS regression
Normally demographers use more sophisticated statistical algorithms (eg. Farrington) to do so. LOWESS is a sloppy technique, but it works well enough for rough estimates
3/n
For more accurate results, I didn't include 2020 data in the LOWESS regression. Instead I cut off the smoothing at 2019, and assume that without COVID-19 the expected mortality would have continued its generally improving trend of the last decades through 2020

The timing of when self-sustained transmission starts is crucial:
A and B are 2 identical countries implementing the same lockdown policy at the same time
If self-sustained transmission starts 𝟱 𝗱𝗮𝘆𝘀 𝗲𝗮𝗿𝗹𝗶𝗲𝗿 in A, then A will have 𝘁𝘄𝗶𝗰𝗲 the number of deaths
This is just math, based on various estimates that the epidemic doubling time of COVID was less than 5 days before lockdowns in spring 2020 academic.oup.com/jid/article/22…
In fact, because of this short doubling time, the timing between self-sustained transmission and lockdown is one of the most important factors that determines cumulative deaths per capita
This explains NYC and the Nordic countries. See next tweet.

• family isolation

• nursing home visit ban
• + many restrictions
I dusted off my COVID-19 model (that predicted the Florida July wave) & applied it to Sweden
After today's data update from the Swedish Public Health Agency (FHM) I confidently forecast Sweden will surpass the peak of 100 COVID deaths/day they had in April
Hard to believe?
1/n
Specifically: by 25 December we will see Sweden has recorded 100 deaths/day around 11 December
(due to reporting delays, it takes up to 2 weeks past a given date to have a complete count of deaths on this date:
