LSOA II Public-use Linked Mortality File (2006)


Description of the LSOA II Linked Mortality File

NCHS has updated the mortality linkage of the Second Longitudinal Study of Aging (LSOA II) to death certificate data found in the National Death Index (NDI). The updated LSOA II Linked Mortality File provides mortality follow-up data from the date of SOA II interview (1994-1996) through December 31, 2006. Mortality ascertainment is based primarily upon deaths previously identified during one of two follow-up interviews, in 1997-1998 and 1999-2000, and results from a probabilistic match between LSOA II and NDI death certificate records. Linkage of the LSOA II survey participants with the NDI provides the opportunity to conduct a vast array of outcome studies designed to investigate the association of a wide variety of health factors with mortality. NCHS recommends that researchers use the new linked mortality file as it supersedes the prior data release of the LSOA II Linked Mortality File.

There are two versions of the LSOA II Linked Mortality File: a public-use file that includes a limited set of mortality variables for LSOA II participants and a restricted-use file that includes more detailed mortality information.
