Censuses (1)
• Population census:
– Size of population by gender and age
– Growth rates
– Housing, employment
• Agricultural census
– Crop production
– Livestock type and numbers
– Income and expenditure
• These censuses are usually carried out
every ten years and provide the benchmark
figures which can be extrapolated by
volume indicators for the years between
censuses.

Living Standards Measurement Study
• The LSMS is a World Bank program helping
countries to measure living standards through
household surveys and community surveys.
• LSMS surveys include modules on a large
number of demographic, social and economic
topics.
• LSMS surveys provide benchmark data for
national accounts on household expenditure and
income, employment, household and business
assets, food intake ….

Enterprise surveys (1)
• Cover enterprises operating from fixed locations
• Often carried out annually but in some countries
less frequently
• Collect data on sales, purchases, inventories,
wages and employment.
• May be tailored to the kind of activity, e.g.:
– Retail outlet
– Restaurant
– Factory

Enterprise surveys (2)
• Short or long questionnaires?
• For the national accounts we are mainly
interested in wages and salaries paid and
profits earned.
• Can we ask directly for profits?
• Or do we need longer questionnaires asking
about all outputs and all inputs?
• Some countries have tried experiments.

Combined Household/Enterprise Surveys
(1-2 Surveys)
Household survey (1)
• Usually a labour force
survey
• Extra questions included
to determine if anyone in
the household is running
a business
• These households form
the survey frame for the
enterprise survey
Copyright 2010, The World Bank Group. All Rights Reserved.
Enterprise survey (2)
• Type of business
• Number of employees
• Family workers
• Sales
• Business expenses
• Value added;
Administrative sources
Government accounts
• Government accounts
– Budget, provisional, final.
– IMF Government Finance Statistics. This is a better
source for the national accounts than the government
accounts themselves.
– Government Final Consumption Expenditure (GFCE)
– Gross Fixed Capital Formation (GFCF). This where you
will find expenditures on infrastructure.
– Strategic stocks
– Consumption of fixed capital (CFC)

Administrative sources
Government Consumption of Fixed Capital
• Government CFC is the using up of government’s fixed capital
assets and is an important part of the costs of producing
government services.
• The SNA requires estimates of CFC in both government final
consumption expenditure (part of GDP(E)) and in government value
added (part of GDP(P)).
• The correct procedure is to estimate PIM from a perpetual
inventory model (PIM).
• If you have no PIM, you can use “depreciation” if this is shown in
the government accounts. But it should be at least 5% of
government final consumption expenditure (GFCE)
• If you have no PIM and no depreciation in the government
accounts, make an assumption that CFC is between 5%-7% of GFCE
depending on the level of economic development .

Lessons?
• National accounts draw on the full range of
statistics collected by the statistical office.
• Some will be out of date and most will need
adjustments.
• National accounts in all countries rely on
administrative data:
– Government
– Regulators
– Private sector
• Don’t forget international sources.
• You can also borrow from another country
