I suppose 'on the planet' is redundant, but what does 'out to' mean here? Is 'out to 2150 with 12 billion people' correct?


Gratefully,

It means that they estimate the population in 2150 will be 12 billion.

I think they have used "to estimate out" as a verb. It is strangely worded and, for me, "out" is redundant and verging on incorrect. The verb is simply "to estimate". I find "They have estimated ... out to ..." very unnatural.

They estimate that the global population in 2150 will be 12 billion.

I don't believe it is "estimate out" as a phrasal verb. They have estimated the population for years in the future. They have done this (from the present, presumably) out to the year 2150.

If they had said "projected" I think the "out" would make more sense.

In any event, simply re-stating it as Mike suggests is the best.
