Denne liste over navnedage i USA i december afslører et rigt udvalg af navne fordelt over hele måneden. Et markant træk er, at mange dage ikke blot har enkelte navne, men derimod hele familier eller varianter af et givent stamnavn. Dette ses tydeligt den 6. december, der præsenterer en bred vifte af fjorten navne centreret omkring Nicholas og Nicole, samt den 29. december med ligeledes fjorten navne fra David- og Jesse/Jessica-slægterne. Andre dage, som den 26. december med den omfattende Stephen/Stephanie-familie og den 16. december med de mange Adelaide/Adela-afledninger, understreger denne tendens. Kalenderen kulminerer med festlige navne som Jesus, Noel og Holly på juledag, hvilket samlet set tegner et billede af en december måned rig på navnearv og variationer.
