When will life expectancy at birth for both sexes reach 60 years in all countries?

Recently, the world quietly marked a significant milestone. For the first time, life expectancy at birth for both sexes now exceeds 50 years in all countries, with Sierra Leone the lowest at 50.1 years. As of January 2019, there are no countries outside of Sub-Saharan Africa where the life expectancy at birth for both sexes is below 60.

This question asks: When, for the first time, will life expectancy at birth for both sexes reach at least 60 years in all countries simultaneously?

By 'for both sexes,' this question refers to the average for both sexes, not a requirement that life expectancy must equal 60 years for women and men individually.

Resolution should cite data from the World Health Organization, United Nations or a similarly authoritative body.

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
