SHARE-Estonia: Study Overview

http://www.share-project.org/home0.html

SHARE is a cross-national panel study of people aged 50 and older and their partners, living in private households in all 26 continental countries of the European Union, Switzerland, and Israel. Its main goal is to provide a multidisciplinary data resource on the influence of health and socioeconomic factors on aging at the individual and societal levels. The survey elicits information about demographics, health, cognition, health care use and costs, employment status, income and assets, housing, and expectations.

The SHARE-Estonia sample is a nationally representative sample of the population aged 50 and older, living in private households in Estonia. The initial sample was recruited in 2010 using a stratified simple random sampling of individuals listed in the national population register.

Age Eligibility	Age 50 and older
People Interviewed per Household	One person per household
Spouse Inclusion	Spouse of any age
Representativeness	Nationally representative
Institutional Representation	Institutionalized respondents included in sampling frame at Wave 4. Respondents followed into institutions
Oversampling	None

The SHARE core interview was carried out every two years through face-to-face interviews, using computer-assisted personal interviewing (CAPI) since 2010.

In addition to the core interview, SHARE-Estonia also collects a number of other types of data.

End of Life Interview	Conducted starting at Wave 5 with someone knowledgeable about deceased respondents.
Life History Interview	Conducted once for all respondents at Wave 7.
Self-Completion Survey	Provided to all respondents at Waves 4-7.
Health Assessment	Conducted at Waves 4-7 for all respondents.
Blood-Based Biomarkers	Capillary blood was collected at Wave 6 among all respondents via dried blood spots.

The SHARE-Estonia Wave 4 sample included 7,416 selected households. Since then, the SHARE-Estonia sample has been refreshed at Wave 6. When a refreshment sample is drawn, individuals are selected from a population register using a stratified sampling.

SHARE-Estonia does not currently include any data linkages, but a linkage is being prepared.

Public access SHARE data are available by request from SHARE - European Research Infrastructure Consortium (SHARE-ERIC). Data are anonymized and available by request from SHARE-ERIC.
