age compression

age compression
 n.— «There can scarcely have been a generation of adults that doesn’t complain that kids seem to be growing up earlier than ever. This time there seems to be some substance to the cliche. The marketers have even coined a term for it—”age compression,” or simply KGOY (kids getting older younger).» —“Children really do grow up faster these days, so how are parents supposed to cope?” by Nick Galvin The Age (Melbourne, Australia) July 29, 2005.
