13.1 Existing publication of NAS and its releases

  • Nature of National Accounts Statistics
    • 13.1.1 The system of National Accounts Statistics (NAS) consists of a coherent, consistent and integrated set of macro-economic accounts - current and accumulation accounts, balance sheets and tables based on agreed concepts, definitions and accounting rules. From the stage of production of goods and services to the stage of their final disposal, innumerable transactions take place. National Accounts help us to understand in a nutshell how these various transactions are inter‑related and give us an idea of the working of an economy. The NAS are compiled to meet the needs of Government, private analysts, policy makers and decision takers. The major use of the NAS is to assess how a country’s economy is performing over time. These data are immensely useful for the purpose of building-up macro-economic models for projecting long and short-term expectations about future prospects. The Gross Domestic Product (GDP), which is the value in monetary terms of all goods and services produced in the economy in a given period of time, is the most important macro‑economic aggregate of National Accounts. It is also used as a denominator for the estimation of rates of saving, capital formation, fiscal deficit, current account deficit, interest payments, expenditure on various social sectors, to name a few.
    • 13.1.2 The Central Statistical Organisation (CSO) in the Ministry of Statistics and Programme Implementation (MoSP&I) is responsible for the compilation of NAS. At the State level, State Directorates of Economics and Statistics (DESs) have the responsibility of compiling there State Domestic Product and other aggregates.
    • 13.1.3 The statistics that are released by the CSO and the State DESs relate to various macro-economic aggregates of the Indian economy. The aggregates compiled and released (at current and constant prices) at annual periodicity by the CSO include gross and net domestic product by economic activity, consumption, saving, capital formation and capital stock, public sector transactions and dis-aggregated statements, as well as the four consolidated accounts of the nation namely, (a) Gross Domestic Product and expenditure, (b) National Disposable Income and its appropriation, (c) Capital Finance; and (d) External transactions. The CSO also releases the quarterly GDP estimates on the last working day of each quarter, the estimates pertaining to the previous quarter. In addition to these macro-aggregates, the CSO compiles and releases the Input Output Transaction Table (IOTT) at a periodicity of 5 years and the State-wise and crop-wise value of the output of agricultural crops at an ad hoc periodicity. The CSO also maintains the database on Gross and Net State Domestic Products, by industry, which is compiled by the State DESs.
    • 13.1.4 The NAS are compiled by the CSO, following the recommendations and guidelines enunciated in the United Nations System of National Accounts (UN-SNA). Recommendations of the latest UN-SNA 1993 are being incorporated into the NAS to the extent permitted by the data system. The base year revisions and changes in the database and methodology of the series of National accounts are effected by the CSO with the consent and approval of the Advisory Committee on National Accounts, which is chaired by an eminent economist from a Non-Governmental Organisation and consists of members from both Government and non-Government institutions and research bodies. The CSO revises the base year of the NAS series, periodically, utilising the work-force estimates available from the Population Census and the quinquennial surveys on employment and unemployment conducted by the National Sample Survey Organisation (NSSO). At the time of the revision of base years, the CSO undertakes a large-scale review of the methodology adopted and the current database that is available on various economic activities of the country.
    • Current Status of National Accounts Statistics
      • 13.1.5 The CSO released the current series of NAS with 1993-94 as Base Year, in February 1999. This series was introduced after a comprehensive review of the database as well as the methodology employed in the estimation of various aggregates. It also involved a number of revisions arising out of conceptual and methodological improvements as well as use of the latest available data. Details of the revisions and methodology adopted are published in the publication of CSO (1999), “New Series on NAS: Base Year 1993-94”. The previous series of NAS had 1980-81 as the base and was released in the year 1987. Base Years have been revised periodically by the CSO in the past, starting from 1948-49 to 1960-61 and 1970-71.
    • Annual National Accounts Statistics
      • Advance estimate of National income and its update
        • 13.1.6 The first estimates of the Annual National Income for a reference year are released by the CSO, about two months before the close of the year, in the form of Advance Estimates (AE) of National Income. These estimates present at both current and constant prices and at factor cost, the Gross National Product (GNP), Net National Product (NNP), Gross Domestic Product (GDP), Net Domestic Product (NDP), and Per Capita Income (Per Capita Net National Product at factor cost) by industry. These estimates are subsequently revised and released on the last working day of June, i.e. with a lag of three months, as updates of advance estimates. The AE are compiled using the methodology evolved by the CSO which is similar to the methodology adopted for the Quick Estimates (QE) and are based on anticipated agricultural production and industrial production, analysis of budget estimates of Government expenditure and performance of key sectors like railways, communication, banking and insurance, available at that point of time.
      • Quick Estimates of National Income and related aggregates
        • 13.1.7 Quick Estimates of NAS and the Revised Estimates of the earlier years are released by the CSO utilising the available data of various sectors provided by the statistical system, in the month of January or February of the following year (with a 10-month lag). Along with the Quick Estimates for the previous financial year, estimates for the earlier years are also revised using the detailed data supplied by various source agencies.
      • Annual Publication of National Accounts Statistics
        • 13.1.8 The detailed methodology employed in the compilation of NAS and the data sources used are given in the CSO publications: (a) National Accounts Statistics- Sources and Methods, 1989, and (b) New Series on National Accounts Statistics: Base Year 1993-94, 1999.
        • 13.1.9 The annual NAS are released by the CSO in its annual publication, “National Accounts Statistics”. This publication follows the Press Note on “Quick Estimates of National Income, consumption expenditure, saving and capital formation”. The NAS publication is divided into 5 parts.

          • Part-V: Disaggregated Statements
            • 13.1.21 ‘Disaggregated Statements’ presents detailed disaggregated statements at the crop/item/category level. The statements include the details of value of output, input and value added for each type of economic activity. Thus the details provided under agriculture relate to the value of output of each of the crops as well as various livestock products and the total inputs used in the sector by items. Under mining and quarrying, the details provided relate to the value of output and inputs of major minerals and minor minerals with further disaggregation of major minerals into fuel minerals, metallic minerals and non‑metallic minerals. The nature and extent of disaggregated data vary from industry to industry depending on the availability of information and procedure of estimation. Besides, disaggregated estimates, in respect of savings, relate to financial assets and the liabilities of the household sector. Capital Formation by type of assets and by type of institutions and external transaction accounts are also presented in this part.
      • Factor Incomes
        • 13.1.22 The publication NAS also presents the factor incomes and property incomes by organised and unorganised sectors and by economic activity. The details of factor incomes provided refer to compensation of employees, operating surplus (in the case of organised sector) and mixed income (in the case of unorganised sector). The details of property incomes provided refer to rent, interest and Financial Intermediary Services Indirectly Measured (FISIM) (earlier referred to as imputed bank charges). Estimates of factor incomes are presented at current prices only.
      • Notes on Methodology
        • 13.1.23 The publication presents at the end, a section of Notes on Methodology, which provides information on the revisions in the estimates indicating broadly the changes in the methodology and new source material used, for the benefit of the users.
      • Special Statements
        • 13.1.24 In addition to the regular statements, special statements are included in the publication to provide from time to time, data on such aggregates/components which are either not of regular nature or which are presented for the first time or which refer to the back year estimates of the current series. Sometimes, memorandum items are also presented in the form of special statements. Special tables are also included from time to time on an ad hoc basis.
      • Releases of National Accounts Aggregates
        • 13.1.25 The CSO releases various estimates of GDP and other related aggregates for a particular reference period at different points of time, utilising the data available at those points of time. While the Quarterly GDP estimates are released with a lag of one quarter, the AE of annual National income are released about 2 months before the close of the year. These AE are subsequently revised and released along-with the 4th quarterly estimates of GDP on the last working day of June, i.e. with a lag of 3 months. The Quick Estimates (QE) of National Income, Consumption Expenditure, Saving and Capital Formation are released generally in the month of January or February of the following year (with a 10-month lag) utilising the latest available detailed data of various sectors provided by the statistical system. Along with the Quick Estimates, the estimates for the previous years are also revised and released simultaneously. Revisions in the quarterly GDP estimates continue together with the corresponding annual estimates. The annual estimates undergo revision for about two to three years after the release of QE. It has been seen that the extent of revision after 3-4 years is only minimal.

          • Note:
            • QE: Quick Estimate;
            • AE: Advance Estimate
            • AE were not prepared at current prices in the Year 1999 and earlier
            • The growth rates are with reference to the latest available estimates at the point in the release cycle in all the above four tables.
        • 13.1.27 Differences between various estimates for the same year arise mainly due to delay in the availability of data on the cost of cultivation studies, land utilisation statistics, Annual Survey of Industries, non-departmental commercial undertakings and data on certain sectors like mining, transport and banking. For a given year, two years prior to the reference year of the Quick Estimate, the estimates are more or less final, after they are discussed with the States. The land utilisation statistics, ASI results, detailed data on the banking sector, are available by this time. The availability of important data at different points of time for a particular year is shown below.

          Table 13.6: Data Used for Compilation of Different Estimates of GDP of a Given Year

          Nomenclature of Estimate

          Availability Of Data

          Advance Estimate

          AE of agriculture production (after the kharif harvest for (July to June) agriculture year), index of industrial production for 8 months, production of data on infrastructure industries and on services sectors like, railways and air in terms of net tonne kms and net passenger kms, cargo handled at major ports, postal and telecommunication revenue, revenue expenditure of Central Government and wholesale/consumer price indices for 8 to 9 months and budget estimates of Centre and States.

          Quick Estimates

          Revised Estimates of agriculture production, index of industrial production, revised budget estimates of Centre and States, reports of commercial undertakings and provisional data on other sectors and prices at All-India level.

          Revised Estimates-1

          Final estimates of agriculture production, provisional ASI results, actual estimates of Centre and States' expenditures, additional reports of commercial undertakings, provisional data on private corporate sector and detailed data on other sectors and prices at State level.

          Revised Estimates-2

          Land-utilization statistics (for grass, fodder and other miscellaneous crops), final ASI results, final data on private corporate sector and detailed data of all sectors.  Estimates are made final in consultation with the State DESs.

          Revised Estimates-3

          Delayed receipt of data in respect of some items under Revised Estimates-2 and reports of commercial undertakings.

    • Recommendations on the publication of NAS and Press Releases
      • 13.1.28 The credibility of NAS has been often questioned by users in the 1990s because of the large differences (in absolute magnitude as well as in terms of growth rates) in sectoral or aggregate estimates in different stages of revisions arising from delays or major revisions undertaken by the source agencies. It is particularly important to minimise the delays as well as major revisions. It is recommended that:
        • The Cabinet Secretariat or a similar high-level authority at the Centre and in the States should impress upon the source agencies to supply the requisite basic data for National Accounts Statistics (NAS) in a timely and reliable fashion by minimising delays and major revisions;
        • The National Accounts Division (NAD) of Central Statistical Organisation (CSO) should explicitly announce the time-table of release of NAS and strictly adhere to it;
        • The NAD of CSO should explicitly provide clarifications for the large differences (magnitude to be specified) from one revision to another for the same year in the sectoral and aggregate estimates along with the mention of the source agencies concerned;
        • The list of such source agencies causing delay and major revisions be notified to the apex technical agency, National Commission on Statistics, which would be in charge of supervising and monitoring the statistical system for information, appropriate action and devising institutional correctives.
