In the Coronavirus Fight in Scandinavia, Sweden Stands Apart

    Sometimes I wonder why I need to explain this over and over and over and over again. The charts from WorldMeters and OurWorldinData have significant delays in recent death data for Sweden. Charts sourced by John Hopkins (like the one I posted from the article) have more up to date data for Sweden. Fortunately OurWorldInData is switching over to John Hopkins.

    Why do COVID-19 deaths in Sweden always appear to decrease in the last 10 days?
    https://ourworldindata.org/covid-sweden-death-reporting

    There are two ways that COVID-19 deaths can be presented over time: by the date of death, or the date on which the death is reported. Neither of these methods is necessarily better than the other—but it can affect comparisons across countries and over time if these methods are not consistent.

    In the data that we present on Our World in Data, which comes directly from the European CDC, deaths in Sweden are shown by date of death, while deaths in other countries are shown by date of report.

    This matters because it takes a number of days until all deaths for a particular day are reported. In practice this means that Sweden might today only report 10 deaths for yesterday, but once reporting is complete the death count for that day might increase to 40.

    The death counts for the last 10 days in Sweden should therefore always be interpreted as an incomplete count of the deaths that occurred in this period.

    How confirmed deaths are presented for Sweden
    COVID-19 deaths are reported by the Swedish government by the date on which the death occurred.

    Since there is a lag between the time a person dies and the time the death is reported, the death counts for the most recent period are always incomplete. They are often most incomplete for the latest 2 to 5 days, but can be incomplete for 10 days or more. This undercount in recent days means that they often appear to be falling; but when this is later completed, data shows that more deaths were occurring during that period.

    This means that for the last 10 days of data, death counts in Sweden must only be interpreted as incomplete measures of mortality.

    As an example, this chart shows what confirmed deaths looked like for the period from October 20 to October 29, when the data was first published on October 30 (red series), and once many more death certificates had been added on November 12 (blue series).

    One day after October 29, it looked as if deaths had peaked on October 27 and then started to fall, but in reality that’s not what happened over this period. What actually happened is shown by the blue series: deaths increased steadily.

    This also means that each day, the Swedish government will add new deaths for multiple days in the past—mostly on recent days, but on average up to 10 days in the past, and sometimes even more, if deaths have been reported with a long delay.

    Our source for COVID-19 deaths, the European Centre for Disease Prevention and Control, updates its figures for Sweden directly from the Swedish government’s data. This means that these daily changes affecting the historical data will be visible on our charts.

    Sweden is the only country for which the European CDC currently applies this method for the reporting of deaths. It is also important to note that this does not apply to confirmed cases, but only to confirmed deaths.

    For other countries, the European CDC does not build its dataset based on the date of death, but rather based on the date of report. More precisely, every morning the European CDC collects each country’s cumulative total number of deaths since the start of the pandemic, and subtracts the previous day’s total from it.

    This results in a daily figure that corresponds to the number of deaths reported in the last 24 hours—regardless of when those deaths actually happened. This means that if the death toll for a country was 20 for a given day, it will remain 20 indefinitely.1

    There is nothing wrong with how Sweden or other countries are reporting deaths. But it is important to know these differences when studying the data from Sweden, and even more when comparing it with other countries.

    (As noted in the article OutWorldInData is switching over to use John Hopkins as their data source as of Dec 1st. This hopefully will reduce the lag in death reporting from Sweden.)

    They're either idiots or intentionally fucking with you. At this point after multiple explanations...I wouldn't cater to their questions about the way Sweden reports their data.

    In fact, I notice on other global statistical websites for Covid-19...two countries are missing...

    Sweden and North Korea.

    strange :D

    Sweden overreports their deaths.
    They may delay them but they definitely overreport.
    If an asymptomatic person with covid dies in a spelunking accident - he is considered a covid death.
    Makes ALOT of sense.

    Maybe its you who needs to put the pipe down? I notice you had no response when you were called out on the data after telling Laces the first time he didn't know what he was talking about, and it was you who was talking out of his ass. Again.

    Certainly looks like there was some catching up. Or perhaps people all decided to wait until Wednesday to die? Even though reported death is less than...say, North Carolina?

    NC has 3.5x the pop density of Sweden

    Ah, that must be it. Only one variable in this equation, I'm sure. Population density.

    Perhaps we can compare cities in Sweden to cities in NC?

    Providing incomplete charts which do not include the last two months of the year is meaning. We will confirm the tally after 2020 closes and the official data from the Swedish government comes out.

    Right, but the data was accurate. And you said it wasn't. And 2019 and previous years are, indeed, final. And this year's pace isn't even close. If you had simply made this comment, nothing would have been said about it. But you shot your mouth off again and ended up with your foot in it.

    And its not like this is the first time that has happened, either. Or the second, or third...or..
