CHAPTER X - NATIONAL ACCOUNTS

ESTIMATION OF GROSS DOMESTIC PRODUCT (GDP) 

In  the  estimates of GDP by industrial origin, the production approach and the income approach are generally employed depending on the type of basic data available. The production approach is followed mainly in estimating the value added by agriculture , livestock and fisheries and manufactured goods (factory industry), while the income approach is adopted in the case of cottage industries and other services (including government). More indirect methods are used in determining the net output of trade, transport and construction

Price indices and quantity indicators are used in deflating and extrapolating the current data to obtain constant price estimates. The constant estimates, base year is 2002.                      

The department releases Annual and Quarterly publications on National Accounts of Sri Lanka. Quarterly publication contains summarized GDP information by eleven sub sectors of GDP and thirteen sub sectors for agriculture. Economic indicators are given in detail in the appendix.

 The annual publication contains more detailed national accounts tables. Those are the consolidated National Accounts tables which are computed and given for disposable income, Gross Domestic Product and expenditure, capital finance and rest of the world accounts. Income and outlay accounts were computed and given for the sectors of general government and households. Reconciliation of key aggregates were compiled for GDP.

Derivation of value added and cost component of value added have been compiled to give detailed breakdown of value added. Supply and disposition tables were prepared to indicate balance accounts for agriculture sector only.                            

According to the implementation of  SNA 93, additional 78 tables are given on production Accounts.

                                 

DISTRIBUTION OF GROSS NATIONAL INCOME 

Figures of aggregate domestic income when adjusted by net factor income from abroad gives the relevant estimates of Gross National Income. Gross Domestic Income is regarded as the sum of rewards accuring to the resident factors of production, which are engaged directly in the current production of goods and services (viz. Salaries and Wages for labour, rent, interests, profits and dividends for other factors of production).

Compensation of General Government is the net value of government services Sector (Government which contains the personal emoluments and pensions of the General Government excluding that of the Public Enterprise Departments). Data on savings of Corporation, and Direct Taxes on Corporations are obtained from the State Accounts (Sessional Papers). In the case of private sector employees, estimates are based on Census data suitably adjusted for changes in population and wage rates data on corporate income and direct taxes are obtained from the Commissioner of Inland Revenue, while particulars of General Government Income and Interest on Public Debt are found in Government Accounts. Income from non - corporate enterprises is taken as a residual.
