Hertfordshire Ageing Study (HAS)
HAS recruited participants by tracing ledgers containing records of 6,803 live births in North Hertfordshire between 1920 and 1930. Over 2,600 people were still alive and resident in the United Kingdom in 1994. Of these people, over 1,400 were still resident in North Hertfordshire and over 800 agreed to be followed up. Participants were aged between 63 and 73 years at the time of first data collection.
