In 1963, documentary director Michael Apted filmed a group of seven-year-olds for Granada TV’s "Seven Up," a project conceived as a study of Britain’s class system through the lives of children selected to represent a broad social spectrum. Those children—ranging from privileged prep school students and working-class Londoners to boys from a care home and suburban Liverpool—were intended to provide a snapshot of England’s future.

Over nearly six decades, the ongoing series has chronicled the participants’ lives, documenting their transitions from childhood into adulthood and old age. The latest installment, "70 Up," serves as the final two-part episode of the series, marking the closure of a landmark social documentary. Two participants—librarian Lynn, who passed away in 2013, and nuclear engineer Nick, who died from cancer after filming this last installment—have died over the project’s extensive run. Michael Apted himself died in 2019, following a successful career that included directing a James Bond film.

While originally intended to examine class divisions, the series has evolved into a broader reflection of post-war British history. The participants’ personal journeys—covering career changes, marriages, parenthood, and, for some, migration abroad—are interwoven with shifts in societal attitudes and cultural norms. For instance, several participants have remarked on their perspectives about mortality, with John, a barrister and hunting enthusiast, expressing a wish to die "just as the hounds are about to go home," and Symon, a foster carer for over 130 children, describing death as "an open door to somewhere else."

The documentary also highlights social changes over the decades. While early terminology and assumptions within the series—such as labeling Symon "illegitimate" or referring to the girls dismissively as "Jackie and her friends"—reflect attitudes typical of the 1960s, these often appear outdated in today’s context. Notably, the original group was predominantly white, with 13 children identified as white, one as mixed-race, and no representation of Muslim or immigrant backgrounds, reflecting Britain's demographic profile at the time.

Beyond individual lives, the series captures shifting trends in fashion, lifestyle, and language. Apted once described the project as akin to time-lapse photography, observing how rapidly life can unfold and change. As the series concludes now, it offers a unique longitudinal perspective on both the individuals involved and the broader evolution of British society since the post-war period.
