The CPR is the percentage of women who are practicing, or whose life partners are practicing, any form of contraception. It is usually measured for married women aged 15-49 years only. The Contraceptive Prevalence Rate (CPR) is calculated on the basis of consumption of contraceptive by converting number of units sold into users.
CPR (%)= No. of Users x 100
MWRA (MWRA=married women of reproductive age)

14. How does Contraceptive Performance data flow?
The District Population Welfare Office collects Contraceptive Performance Reports from all reporting units (Family Welfare Centers, Reproductive Health Services Centers-A, Mobile Service Units etc.), After consolidating, these reports are transmitted to its provincial Population Welfare Department. The provincial Population Welfare Departments forward these reports to Pakistan Bureau of Statistics. Apart from the provincial departments, FATA, AJK, GB, eminent NGOs (FPAP, Marie Stopes and SMC) also provide Contraceptive Performance data to PBS for compilation of quarterly & annual reports.
15. What are the objectives of Contraceptive Performance Reports?
These reports provide basis for estimating annual contraceptive requirement and distribution in the country.

Statement showing yearly indices and %change in CPI, SPI & WPI
(Base year 2007-08=100) How one can obtain the historical data regarding prices/price indices?
The historical data regarding price indices/prices can be obtained on demand according to PBS data dissemination policy.
17. How PBS assign weights to different items?
For CPI, Family Budget survey was conducted during 2007-08 and weight for each item were assigned according to consumption pattern of the households.

The value of marketable surplus is the value of item available for sale in the wholesale market, which is equal to the total value of production less consumption by producer plus imports, minus export if any.
18. Which classification is being used by PBS?
COICOP (Classification Of Individual COnsumption according to Purpose) is currently being used for CPI items, while CPC (Central Product Classification) is being used for WPI items.
19. What is the schedule for release of Price indices?
PBS is releasing the weekly SPI report on every Friday, while CPI, WPI & monthly SPI figures are released on 1st or 2nd of every month.
20. How many items are included in the basket of goods and services of CPI, SPI and WPI?
The basket of CPI comprises of 487 items, WPI comprises of 463 items, while SPI basket comprises of 53 essential items.
21. What formula is being used for computation of Price indices by PBS?
The weighted Laspeyre’s formula is used for computation of price indices.
22. What is the coverage of Price Indices?
Detail of coverage is as under:
- SPI prices are being collected from 53 markets of 17 cities.
- CPI prices are being collected from 76 markets of 40 cities.
- WPI prices are being collected from 21 wholesale markets of 21 cities.
23. What is base year of current Price Indices?

PSLM District level survey collects information on key Social indicators whereas through provincial level surveys (Social & HIES) collect information on social indicators as well as on Income and Consumption. So HIES is conducted under the umbrella of PSLM.
30. How the reliability of the estimates can be obtained?
Coefficient of variation (CV) is used to obtain the reliability of estimates.
31. How you allocate sample size for the survey?
Allocation of sample size for a particular sample survey among ultimate strata is made using Proportional allocation methodology.
32. How you determine the sample size for the survey?
The different estimation formulas are used for computation of sample size at desired level of confidence with certain margin of errors. Consequently, sample size is fixed keeping in view the available resources and time constraints.
Which sampling technique is used by PBS for the ongoing sample surveys?
Two stage stratified random sampling technique is used.
33. What is the status of up-dation of new sampling frame?
Updation of new sampling frame for rural areas is in progress through a development project.
What is a Quick Count Technique?
The “Quick Count” is the process of counting structures, households, dwellings, establishments, industries, within a demarcated block by going around without undertaking listing.

All the Geographical areas notified by the respetive provincial Govnermnet authoirties as urban areas is called as on urban areas while rest is rural areas. The blocks formed in there two domains are called urban and rural PSUs. In both Rural and Urban domains the enumeration blocks are taken as Primary Sampling Units (PSUs).

Primary Sampling unit is a geographical urban/rural area containing 200-250 households on the average, which is generally called as Enumeration block.
