The smallest EVER generation is THE WAR BABIES, which they are lumped into the "SILENTS" in this article. And the end date is 1946!
And the "SILENT" used to be called "THE GREATEST", which is also a VERY recent renaming.
The “silent generation” used to be 1925-1945 but in recent years I see the numbers 1928 to 1945 a lot.
The GI generation which is about 1901 to 1925 (or 1928 sometimes) is being labelled by Tom Brokaw’s term “greatest generation” now.
