What is the LS?
• Approximately 1% sample of population of England and
Wales
• Initial sample drawn from 1971 Census
• Selected if birthday falls on one of four days in each year (‘LS
birth dates’)
• Maintained through addition of immigrations and new births
with LS birth dates
• Losses to sample through deaths and out-migrations (though
all records are retained in the database)
• Data from the census and from vital registration (‘events’)
• Census data for the whole household available for each
sample member
