Living Standards Measurements Study - Serbia 2002 - 2007

status was unknown at the time of the listing were
included in the second stage sampling frame to
ensure that any households in these dwelling units
were included in the frame; some of these dwelling
units were found to be unoccupied at the time of the
LSMS interview. Excluding the sample dwelling
units in category (6), the unweighted unit response
rate for the 2007 LSMS is 80.6 percent.
It can be seen that the main reason for
noninterviews was (3) Refusal. Although this
response rate is considered reasonable compared to
that for other household surveys, the characteristics
of the 19.4 percent of sample households that did
not respond may be somewhat different from those
of the responding sample households, resulting in a
corresponding bias in the survey results.
The first two components of the weight and the
non-interview adjustment factor were calculated at
the level of the sample ED, and were attached to the
data record for each household in the ED. This
dwelling unit weight was then multiplied by the
number of households in the sample dwelling unit
(k hij ) for each household record. The final weights
based on these specifications were generated by
Mira Ogrizovic, RSO using the SAS software, and
independently verified by the consultant David
Megill.
The weights specified above are based on the
sample design. It is important to examine the
weighted estimates of the total number of
households and population by stratum (region,
urban and rural) in order to compare these results to
the population distribution from the 2002 Census
and other sources. This enables evaluation of the
implementation of the sample design and identifies
potential biases in the sampling frame.
