6. Task Force on Health Expectancies 2 December 2008Page 6 To present the disagreement between MEHM and the questions used in the Danish-SILC Can the differences influence e.g. HLY estimates? Data from the Danish SILC-2006 and the Danish Health Interview Survey in 2005 was used to investigate the influence Purpose

Task Force on Health Expectancies 2 December 2008Page 7 SILC - Denmark Is carried out under EU legalisation The reference population is private households residing in Denmark 1 January 2006 and members of these households SILC has a rotating panel design In total, SILC-2006 consists of 9,492 sampled persons/ households (16 years or older) selected from the Central Population Register Number of respondents: 5,711 households (60%) Data were collected via telephone interview and postal questionnaires by Statistics Denmark
