I'm not clear on what I'm wrong about. Doesn't FM also lose most of their
listeners, in absolute numbers (not percentage) during the night? What
are
those numbers?

The difference is that FM actually increases share of available listeners at
night, while AM decreases. All radio has different listening levels at
differnt times. From 6 Am to 7 PM, it is around 22%, while at night it is
more like 7%... keeping in mind that 7 PM is "daytime level" and 11 PM most
people are asleep and it is around 3% of the universe.

Whaterver the listening level, FM takes more of it at night.
