The Healthy Life Years (HLY) indicator measures the number of remaining years that a person of a specific age is still expected to live in a healthy condition. In the case of the Eurostat HLY, a healthy condition is defined by the absence of limitations in functioning/disability.
HLY is calculated using Sullivan's method, which combines information on mortality and morbidity. Information on mortality is taken from life tables. Information on morbidity is based on prevalence measures, such as the age specific proportion of the population in healthy and unhealthy conditions.
Data were obtained from the ECHP (European Community Household Panel) for the years 1995-2001 for EU-15 Member States (excl. Luxembourg). The ECHP used the following two questions for obtaining data on the prevalence of limitations in functioning:
- Do you have any chronic physical or mental health problem, illness or disability?
And if the answer is yes:
- Are you hampered in your daily activities by this physical or mental health problem, illness or disability?
| For 2002-2003 the prevalence data are estimated on the basis of the trend from 1995-2001. In the case of the new Member States and EFTA countries national sources were used when comparable.

The ECHP was carried out during the period 1994-2001 (Eurostat). The ECHP is a longitudinal, multi-subject survey covering many aspects of daily life, particularly employment and income, but also demographic characteristics, environment, education and health. The ECHP is a unique source of information due to its three main characteristics. These are (1) its multidimensional coverage of a range of topics simultaneously, (2) a standardised methodology and procedures yielding comparable information across countries and (3) a longitudinal or panel design. This longitudinal design makes it possible to follow up and interview the same private households and persons over several consecutive years. In all, the sample covers some 60 000 households comprising 130 000 adults aged 16 or over at 31 December of the previous year. The first wave took place in 1994, when the EU had only 12 Member States, so Austria, Finland and Sweden were not included.
