What is "cheaper by the dozen"

phr. (context idiomatic English) Things are handled more efficiently as a group, rather than individually.

Cheaper by the Dozen is a 2003 American family comedy-drama film which takes its title from the autobiographical book of the same name by Frank B. Gilbreth, Jr. and Ernestine Gilbreth Carey, but despite the title and the concept of a family with twelve children, the film bears no resemblance to the book nor its original film adaptation, although it is mentioned that the mother's maiden name is Gilbreth. The film was directed by Shawn Levy, narrated by Bonnie Hunt, and starring Steve Martin. The film was released on December 25, 2003 by 20th Century Fox, ultimately grossing just over $190 million worldwide.

Cheaper by the Dozen is a 1950 Technicolor film based upon the autobiographical book Cheaper by the Dozen (1948) by Frank Bunker Gilbreth, Jr. and Ernestine Gilbreth Carey. The film and book describe growing up in a family with twelve children, in Montclair, New Jersey.
