#PowerShell, 53 Bytes

    $n=date -f yy;"$(.1*[int](61.45+.75*$n)),$(280+3*$n)"

Uses a similar rounding trick as muddyfish's [Python 2 answer](http://codegolf.stackexchange.com/a/57805/42963) to simplify the world population calculation, since PowerShell implicitly `Round()`s when you cast from a `[double]` to an `[int]`, rather than truncating.

For the output, we use built-in command blocks `$(...)` that get executed before the string literal `"..."` is executed, so we have our results already calculated into the string before the string is printed, saving several bytes.
