What percentage of US residents will be aged 100 years or older on January 1 2050?

We have a number of questions regarding possible achievements in life extension, but none that measure the effect these achievements might have on a large cohort of people.

In 2005, the US Census Bureau estimated the country would have 114,000 centenarians by the year 2010. The actual number reported in the 2010 census was less than half that amount at exactly 53,364 people, or approximately 0.0173% of the population at the time.

As of 2014, estimates by the Centers for Disease Control and Prevention, place the number of American centenarians at approximately 72,000, roughly 0.022% of the population at the time.

This question asks: what percentage of US residents will be aged 100 years or older on January 1 2050, according to data released either by national statistical authorities such as the Centers for Disease Control and Prevention, the National Center for Health Statistics or other credible independent statisticians?


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.

Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

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.
