Discrepancies




For the year 2001 , data based on the
population Census.
For the year 2006 and 2007 based on
the surveys. SSMDG and SLLFS
There is no discrepancies in between
National and International data.
Even no gender disparity.
16
RELIABILITY OF THE ESTIMATES
 Statistics based on the quarterly labour force
data are subject to both sampling and non
sampling .There is a chance that the sample
estimates may differ from the true population
value they represent.
 The sampling error varies depend on the
particular sample selected and this variability is
measured by the standard error of the estimate.
 Analysis relating to the SLLFS are generally
conducted at the 95 percent level of confidence
