National Gross Domestic Product by Income and by Expenditure Accounts
Detailed information for first quarter 2016
The National Gross Domestic Product by Income and Expenditure Accounts (IEA) give a comprehensive statistical picture of Canadian economic developments. The GDP by Income and by Expenditure is the centre of macroeconomic analysis and policy-making in Canada.
Data release - May 31, 2016
The Gross Domestic Product (GDP) and Income and Expenditure Accounts record the production of goods and services in the economy, the incomes arising from this production, expenditures on production and the resulting saving (dissaving), investment, The recording of the information in a series of interrelated accounts means that analysts can formulate consistent interpretations of productive activity, income, expenditure, saving, investment, financing and wealth. The information is presented in the form of economic accounts that parallel, to some extent, the statements used in business accounting. The economic series' estimates that appear in a number of accounts are identical and/or consistent, because common definitions, classifications and valuations are used across the entire set of accounts.
Gross domestic product (GDP) lies at the centre of the national economic accounts.
GDP is the unduplicated value of goods and services produced during a period that is available for final domestic consumption, investment or export. The National Economic Accounts record the value of GDP from two perspectives, as income arising from production and as final expenditure on goods and services produced. In real terms (that is, adjusted for price change), GDP is representative of the volume of economic activity in a given period. The national production account provides a measure of gross value added by industry¿total output (or sales) less intermediate consumption.
The Income and Expenditure Accounts record the distribution and use of income by the six main institutional sectors: households, non-profit institutions serving households, general governments, non-financial corporations, financial corporations and non-residents. These accounts articulate revenues to the sector (including current transfers from other sectors, such as employment insurance received) and current expenditures of the sector (including transfers to other sectors, such as income taxes paid to government). The difference between a sector's current income and expenditure represents the sector's net saving.
The accumulation of capital is also central to the sector accounts. The capital (or investment) account's focus is on economic agents' decisions regarding investment in non-financial assets. The account records whether a sector's current period savings are sufficient to meet its demand for funds (for investment). The balance of the capital account represents each sector's net lending (saving greater than investment) or borrowing (saving less than investment).
The Canadian System of National Accounts (CSNA) provides a conceptually integrated framework of statistics for studying the state and behaviour of the Canadian economy. The accounts are centered on the measurement of activities associated with production of goods and services, the sales of goods and services in final markets, the supporting financial transactions, and the resulting wealth positions.
To produce financial statistics, the CSNA measures the economic dimensions of the public sector of Canada, including the financial inter-relationships among the thousands of entities that make up the three levels of government in Canada (federal, provincial and territorial, and local). In order to carry out this program, the CSNA maintains a universe of all public sector entities including their complex inter-relationships.
Collection period: In general, the GDP and Income and Expenditure Accounts are compiled using a variety of data sources and published 60 days following the reference period.

Data sources and methodology
The GDP and Income and Expenditure Accounts respect the production boundary defined by the 2008 System of National Accounts. This includes the economic activities of all establishments, enterprises, households, non-profit institutions serving households', governments, financial corporations, non-financial corporations operating within the economic territory of Canada. It also includes all interactions (e.g. imports, exports, distribution and receipt of incomes) with non-residents.
Data are extracted from administrative files and derived from other Statistics Canada surveys and/or other sources.
A broad range of survey and administrative data sources are used to compile the GDP and Income and Expenditure Accounts. Some of the more notable sources include: the quarterly survey of financial statements, the monthly survey of employment, payroll and hours, the quarterly retail commodity survey, annual business surveys, banking information, Government Finance Statistics, the Balance of Payments statistics, and the T4 remuneration file from the Canadian Revenue Agency. All of these data sources are adjusted to conform to the 2008 System of National Accounts concepts and definitions and integrated into the 2008 System of National Accounts macroeconomic accounting framework.
The GDP and Income and Expenditure Accounts are estimated by taking the most complete and high quality data sources available to establish benchmark annual estimates. This generally entails taking annual business surveys, administrative data files from the Canadian Revenue Agency or annual household survey files and integrating them into the 2008 System of National Accounts framework to establish annual estimates. The annual benchmarks for gross domestic product by the income approach and by the expenditure approach are generated through the construction of annual supply and use tables which balance the supply of each product in the economy against its use. These tables present the most complete and accurate depiction of Canadian economic activity.
The sub-annual estimates are generated by applying the movements of sub-annual surveys such as the quarterly survey of financial statements, monthly survey of manufacturing, the monthly survey of payrolls, employment and hours.to the benchmark estimates.
The majority of the components of the sub-annual GDP and Income and Expenditure Accounts are presented on a seasonally adjusted and unadjusted basis. Seasonal adjustment is performed using the X12 ARIMA method of seasonal adjustment. In addition, certain series (mainly expenditure series) are deflated (presented in real terms to estimate the volume of economic activity occurring within an accounting period. For example, Gross Domestic Product by the expenditure approach is presented in both nominal and real terms.
Given the GDP and Income and Expenditure Accounts are compiled from a variety of diverse data sources it is not possible to produce typical survey-based quality indicators such as coefficients of variation or survey response rates. Instead data are analyzed for time series consistency, links to current economic events, and coherence in source data.
Since the GDP and Income and Expenditure Accounts measure gross domestic product from two perspectives (incomes and expenditures) - the compilation process itself is an important quality control on the data. Differences between GDP measured by income and GDP measured by expenditure highlight inconsistencies in the source data leading to coherence adjustments that improve the overall quality of the estimates. In addition, the National Income and Expenditure Accounts embed a number of important accounting identities such as economy wide transfers received must equal economy wide transfers paid. Adherence to these identities and the investigation and resolution of imbalances when they arise is another quality feature of the system.
Statistics Canada is prohibited by law from releasing any information it collects which could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data.
Revisions and seasonal adjustment
Revisions - Statistical revisions are carried out to incorporate the most recent information from quarterly and annual surveys, taxation statistics, public accounts, censuses, etc., as well as from the annual benchmarking process of the supply and use tables.
Data are released within 60-75 days after the reference period. Estimates for each quarter are revised when those for subsequent quarters of the same year are published. At the time of the third quarter of each year, revisions are generally undertaken back three years. They are not normally revised again except when periodic comprehensive revisions are carried out to incorporate the latest international concepts, classifications and estimation methods.
Seasonal adjustment - Seasonal adjustment is generally made at the lowest level of aggregation, and seasonally-adjusted aggregates are obtained by summation. Statistics Canada's X-12 ARIMA is used to seasonally adjust series.
The accounts are designed as a double-entry system in which the income- and expenditure-based GDP totals should, in principle, be identical. In fact, a difference virtually always arises between them due to errors in the source data, imperfect estimation techniques, differing seasonal adjustment methods and discrepancies in the time at which the incomes and expenditures are recorded.
The size of the discrepancy, which stems from the estimation procedure, is one gauge of the system's overall reliability. However, it is only a partial gauge.
No direct measures of the margin of error in the estimates can be calculated. The quality of the estimates can be inferred from analysis of revisions and from a subjective assessment of the data sources and methodology used in the preparation of the estimates.
