How to Calculate Week-specific Age-standardized Death Rates from STMF Data?

Dmitri Jdanov: “The Short-Term Mortality Fluctuations (STMF) data series provides an opportunity to analyze intra-annual excess mortality, in particular, due to the COVID-19 pandemic. Nevertheless, the STMF has a limitation caused by the nature of the collected original weekly death counts. In many countries, weekly death counts are available only by broad age groups or/and are too small and shaky. Moreover, the original age scales somewhat vary by country. Thus, the STMF data file presents weekly deaths and death rates by broad age intervals. The comparisons may be biased due to differences between the population age composition. Our new paper addresses the problem by providing a method for the estimation of week-specific standardized death rates (SDRs) that combines the aggregated weekly mortality data with detailed annual data on mortality and population. We are planning to include SDRs in the STMF data series soon, too.”

Which Cohort Accounts for Most of the Years of Life Lost?

Mikko Myrskylä: “To properly assess the impact of the COVID-19 pandemic on mortality, it is not enough to only count the number of dead. That's why we evaluated more than 1.2 million deaths attributed to COVID-19 in 81 countries to learn how old the people who died from COVID-19 were, and how much their lives were shortened compared to the average life expectancy. Middle aged people and those in early retirement bear the largest share of total years of life lost in global comparison.”

How to Visualize COVID-19 Excess Mortality in 38 Countries
László Németh: “Currently, the STMF data series contains weekly death counts and death rates by age and sex for 38 countries and regions and is still growing. We decided to add a visualization layer to the database to simplify access to the data. In doing so, we want to enable users to explore the data, enhance the basic understanding, and stimulate research on mortality outbreaks and seasonal variations.”

How the Covid-19 Pandemic Amplifies Existing Trends in Demographic Research

Emilio Zagheni: “Digital trace data are not the result of the pandemic. But Covid-19 has likely changed the perception that companies, scholars and professional organizations have of these data. That opened new opportunities for progress. Some of the mixing between industry and academia is likely to have planted the seeds for new forms of joint ventures. If appropriate measures are developed to guarantee privacy, data-protection and ethical frameworks for the use of digital traces, the pandemic may mark a milestone for the rapid acceleration of partnerships between scientists and holders of private data and infrastructure.”
