#PowerShell, 53 45 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 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 assume that "followed by some delimiter (e.g. space or comma)" can also mean "newline", so we execute one result and then the second. PowerShell implicitly writes out results, so we don't need to explicitly call any printing commands.

Uses a similar rounding trick as muddyfish's Python 2 answer 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.
