Since your parents were first interviewed when you were born, there have been ten further surveys of NCDS study members. In 2020, we will start the 11th survey at age 62.

COVID-19 Survey

We invited participants to take part in two special online COVID-19 surveys in 2020. We will be sending participants an invite to complete a third survey in early 2021.

Age 62 Survey

In light of current government guidelines on the importance of social distancing to minimise the spread of COVID-19, we will not be conducting any further interviews or nurse visits for now. Please continue to check here for updates.

Age 55 Survey

The Age 55 Survey took place between 2013 and 2014. This was the first time we asked you to complete a survey via the internet. We asked you about your relationships and work, your expectations for retirement, and your caring responsibilities. More than 9,000 of you took part with two thirds doing so online.

Age 50 Survey

The Age 50 Survey took place in 2008. Age 50 marked a big milestone in your lives, and this survey aimed to find out about what your lives were like at this age. We even asked you to write a little about how you imagined your life to be at age 60. Just under 10,000 of you took part.

Age 46 Survey

The Age 46 survey took place in 2004 and was conducted via telephone. We asked you about your lives in middle age, including your relationships, work, use of computers, smoking and drinking habits, and your experience of crime. Just under 10,000 of you took part.

Biomedical Survey (Age 44/45)

The biomedical survey took place between 2002 and 2003 when you were 44/45 and aimed to explore the factors associated with health in early middle age. A set of measures were taken and many of you gave blood, and saliva for analysis. Over 9,000 of you took part.

Age 7 Survey

The Age 7 Survey took place during 1965 and aimed to measure your educational, social and physical development. Over 15,000 of you took part.

Birth Survey

The first survey took place the year you were born. It was known as the ‘Perinatal Mortality Study’ and was focused on investigating the health of mothers’ new-born babies’ health in Great Britain.


There have been a number of ‘sub-studies’ that have collected information from a smaller number of study members on special topics, such as being a twin, disabled school leavers, and adult basic skills.
