Q: Do Women live longer (from birth) than Men?

It may be well known and widely accepted that women live longer (from birth) than men. This is an important societal and demographic question, whether woman live longer than men, and the possible reasons for that difference. Recently, a new study carried out by a Danish research team, came to "nearly" the opposite conclusion. The conclusion from the Danish group is, certainly nuanced- excerpted in full below:

Premise

• Possibly an example for statistics students to replicate with the freely available data used in the publications
• two very different statistical  methodologies, and two different datasets, that, without a critical statistical insight seem to address the same question but yield different results,
  and the media
• Media balanced reporting vs media hyperbole "everything you learned is a lie"

 Recently a Danish group used data assembled from about a  200-year period. Relative to population level survival analyses, by say, CDC or Census, the Danish data led to a new finding as to survival (from birth) of women vs men. The 'traditional' Method 1 are Population lifetable uses survivors (at risk of death) and deaths, and "Demographer" Method 2, demographers use age (from birth) at death only among the deaths. Unsurprisingly the two methods do not yield identical results. . In some sense Both are "right"

Key Danish Finding

Men have a high probability  of outliving women

Men have a high probability of outliving women-especially those who are married and have a degree-reveals a statistical analysis spanning 200 years across all continents of the globe and published in the open access journal BMJ Open. Between 25% and 50% of men have outlived women, challenging the received wisdom that men simply don't live as long as women, say the researchers, who point out that sometimes large differences in life expectancy mask substantial overlap in lifespan between the sexes. The female survival advantage has been observed over time across many different populations. But sex differences in survival are often identified by comparing life expectancy, which summarises the average length of life, rather than years lived, and this has been interpreted as 'men do not live as long as women,' explain the researchers.

Key CDC/NCHS/Census finding to date

…And researchers estimate that the gap in longevity will continue. According to the U.S. Census Bureau, women's life expectancy is projected to reach 87.3 years by 2060, compared with 83.9 years for men.  …

and some media hyperbole about the finding - my attached materials include news sources that excerpt the exact findings from the research

Hello and welcome to today's edition of 'everything you know is a lie!' – as new data has flipped the long-held belief that women, in general, live longer than men. However, it's not quite as straightforward as 'if you're a man, you've got an extra ten years no matter what', as there are certain lifestyle factors and caveats that the researchers observed along the way.
