This is the second analytical report containing district
level indicators of the PSLM Survey. It provides an overview of the findings
in all sectors at district levels. Given that the PSLM is a large, complex
household survey that collects information on a number of different topics,
the tabulations presented here comprise the detailed tables at National/
Provincial/ District levels in continuation of the National / Provincial
level report which has already been released |

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 constitutes 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 district in all the provinces has been grouped together to form a
stratum.
B. Rural Domain: Each district in the four provinces of Pakistan has
been treated an independent stratum.
Sample Size and Its Allocation: Keeping in view the objectives of the
survey the sample size for the four provinces has been fixed at 73953
households comprising 5198 sample villages / enumeration blocks, which is
expected to produce reliable results at the district level.
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. Village wise population of 1998
census and enumeration block wise number of household collected in 2002-03
updation of urban sampling frame have been treated as measure of size for
selection of sample PSUs in rural and urban strata.
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.
Detailed sampling plan is attached as Appendix- A

Data quality in PSLM Survey has been ensured through
built in system of checking of fieldwork by the supervisors in the field as
well as teams from the headquarters. Regional/ Field offices ensured the
data quality through preliminary editing at their office level. The entire
data entry was carried at the FBS headquarter Islamabad and the data entry
programme used had a number of in built consistency checks. This is the 2nd
round of district level survey and it has been observed that overall
indicators do follow the usual pattern at national/provincial levels.
However, in certain districts particularly for Balochistan province there
are variations in indicators between 2004-05 and 2006-07 which may be due to
prevailing situation in the province, which probably lead to under/over
reporting of events. |
