This is the fourth round report of the PSLM series of
surveys to be conducted between 2004-2009. The PSLM is a large, complex
household survey that collects information on a number of different
sections, the tabulations presented here comprise the tables at National/
Provincial level and detailed analytical comparison has been carried with
previous rounds of PSLM and PIHS. Some of the tables have been presented
based on consumption quintiles. The methodology of computing quintiles based
on consumption is explained in Appendix-B |

Universe: The universe of this survey consists of
all urban and rural areas of the four provinces and Islamabad excluding
military restricted areas.
Sampling Frame: FBS has developed its own urban area frame,
which was up-dated in 2003.Each city/town has been divided into enumeration
blocks consisting of 200-250 households identifiable through sketch map.
Each enumeration block has been classified into three categories of income
groups i.e. low, middle and high keeping in view the living standard of the
majority of the people. List of villages published by Population Census
Organization obtained as a consequence of Population Census 1998 has been
taken as rural frame.
Stratification Plan:
A. Urban Domain: Islamabad, Lahore, Gujranwala, Faisalabad,
Rawalpindi, Multan, Bahawalpur, Sargodha, Sialkot, Karachi, Hyderabad,
Sukkur, Peshawar and Quetta, have been considered as large sized cities.
Each of these cities constitute a separate stratum and has further been
sub-stratified according to low, middle and high-income groups. After
excluding population of large sized city (s), the remaining urban population
in each defunct Division in all the provinces has been grouped together to
form a stratum.
B. Rural Domain: Each district in the Punjab, Sindh and NWFP
provinces has been grouped together to constitute a stratum. Whereas defunct
administrative Division has been treated as stratum in Balochistan province.
Sample Size and Its Allocation: Keeping in view the objectives of the
survey the sample size for the four provinces has been fixed at 15512
households comprising 1113 sample village/ enumeration blocks, which is
expected to produce reliable results.
Sample Design: A two-stage stratified sample design has been adopted
in this survey.
Selection of Primary Sampling Units (PSUs): Villages and enumeration
blocks in urban and rural areas respectively have been taken as Primary
Sampling Units (PSUs). Sample PSUs have been selected from strata/sub-strata
with PPS method of sampling technique
Selection of Secondary Sampling Units (SSUs): Households within
sample PSUs have been taken as Secondary Sampling Units (SSUs). A specified
number of households i.e. 16 and 12 from each sample PSU of rural & urban
area have been selected respectively using systematic sampling technique
with a random start.
