There are an awful lot of variables in this. It depends on the manufacturer, the construction techniques that they used, when the boat was built, how it was maintained....
Delamination is not a fixed "fact". My boat is 42 years old and the deck core is bone-dry and rock solid. There are newer boats out there where the deck is squishy and hollow.
The easy answer is, buy yourself a moisture meter and/or pay for a survey. The moisture meter is a good investment in telling you whether or not you should even bother with a survey. At the very least, tapping around with a screwdriver handle or a phenolic hammer will show changes in tone as you tap around, which may indicated a soggy core.
