4. Introduction
GDP by economic activity, i.e. GDP(P), are compiled on a quarterly and annually at both current & constant 2006 prices basis;
The estimates of GDP are compiled in accordance with the principles and concepts of the SNA93;
Quarterly GDP estimates are published via NISR website since October 2011;
First estimate 3 months while revised 9 months
Annual estimates are obtained by summing up the relevant quarterly estimates.

5. Methodology
August 6, 2018

6. Production approach
The current methodology depends on establishing a “benchmark” every five years.
The quarterly GDP(P) estimates are based on extrapolating 2006 benchmarks using two types of indicators:
value indices (for current price estimates) and
quantity indices (for constant price estimates).
Benchmark estimates are available for every kind of activity of Total output, IC, and GVA.

7. Production approach (cont)
Value indices:
There are 2 methods of producing value indices:
First, when figures for the turnover are available directly, these can be converted into a value index.
These turnover data are available for the formal sector and equivalent figures for producers of government services.
Second, where turnover figures are not available directly, a value index can be obtained by multiplying a quantity index by an appropriate price index.
This is what we do for Agriculture and the rest of informal sector.

8. Production approach (cont)
Quantity indices:
There are several methods of deriving a quantity index:
If a value index exists, it can be divided by an appropriate price index.
If quantity data are available, they can be converted directly into an index number.
If neither values nor reliable quantities are available, proxy indicators of quantity may have to be used. In some cases the quantity indices are based on the population growth rate.

9. Production approach (cont)
Annual estimates:
Annual estimates are derived by summing the quarterly estimates.
The main sources for the indicators are: banking data, BOP, Crop assessments, Government finance data, Population projections, Trade data (Import export), Price data (CPI & PPI)and tax data (VAT).

10. GDP at market prices
Once the estimates of GVA by activity have been made, two adjustments are required in order to convert total GVA at basic prices into GDP at market prices, both current and constant.
The first is for Financial Intermediation Services Indirectly Measured :FISIM (formerly known as imputed bank service charges)
The second is taxes (less subsidies) on products.
August 6, 2018

11. Expenditure approach
GDP by expenditure share, i.e. GDP(E) is NOT independently compiled. Therefore, hard to verify GDP(P).
The difference between the total GDP(P) and the sum of other items of expenditure (Government final consumption expenditure, GFCF, and net-export) is reported as private consumption.
Separate estimates for household final consumption expenditure, consumption of non-profit institutions serving households, and changes in inventories are not compiled.

12. Mode of production
Formal sector has been defined as businesses registered for VAT excluding agriculture (agro-industries such as tea and coffee processing are included)
For largest enterprises, banks and insurance companies, these data are supplemented by the detailed annual (for banks, quarterly) financial accounts.
Informal activity covers marketed production by all other private producers not registered for VAT
Apart from crop production (use of “crop assessment data”)estimates are produced by extrapolating the benchmark using proxy indicator.
August 6, 2018

13. Mode of production (cont)
Non-monetary production covers goods (mostly crops) and housing services that are consumed by the producer (auto-consumption). These proportions are assumed to be constant between benchmarks.
The Government and NGO mode of production is assumed to be activity carried out in three branches of activity, namely public administration, education and health.

16. Gaps The main gaps include:
Better estimates of agricultural production
through joint collaboration between NISR and MINAGRI
this process has started
Quarrying
Quarterly estimates of road constr.
Quarterly BOP (especially services)
Quarterly insurance data
Timely school enrolment data

17. Improvement
The NISR is committed to improving the GDP estimates and to expanding the range of NAS aggregates:
Current improvement:
Replacing use of population indicators with more representative indicators;  from 19% to 7.4%
Increasing use of existing NISR survey data (e.g. Pop. Census 2002, EICV2, NAS 2008).
August 6, 2018

18. Plans for Improvement (2012 to 2014)
Increasing access to, and/or use of, existing administrative source data (e.g. Income tax, RAB, RURA, RTDA, Ministries);
Finalizing results of EICV3 ;
Conducting benchmark agriculture, RGPHC, IBES (enterprise and NGO surveys);
Developing detailed benchmarks based on Input-Output Tables (IOT) and Supply/Use Tables (SUT);
Rebase of GDP to 2011 base year;
Expanding and improving annual and sub-annual data collections (e.g. for Agriculture, PPI); and
Redeveloping the NAS compilation methodology and worksheets (Crop WIP, construction model etc)
