Age 46 Survey (2004)
Centre for Longitudinal Studies, Institute of Education
The 2004/2005 follow-up extended the data collection of the previous NCDS surveys in line with the Forward Plan for the cohort studies, developed in 2002 by the then Director of CLS, Professor John Bynner. This sought to integrate the timing, design and analysis of future surveys of NCDS and BCS70 – taking account of the sequencing of Britain’s third birth cohort study, the 1946 cohort (NSHD, housed at UCL). This would enable comparisons between cohorts born at different times, or between different age groups at the same point in time.
In 2004, CLS was granted long-term funding as an ESRC Resource Centre to establish a stable infrastructure for the study and ensure that fieldwork is conducted at regular intervals.
The Centre for Longitudinal Studies led the development of the 2004/5 survey and commissioned the fieldwork. This latest sweep was conducted for the first time as a telephone interview, when the cohort members were 46 years of age.
