Integration of Agricultural Statistics into National
Statistics System in Brazil

Meeting of the FAO/OEA-CIE/IICA Working Group on Agricultural and Livestock

Statistics for Latin America and the Caribbean (25th Session)
Rio de Janeiro, Brazil, 10-12 November 2009
Integration needs
(a) on surveying common
aspects of different objects
of investigation
guaranteed standardization of
concepts
(b) on surveying related
matters or chain activities
to establish mechanisms that
guarantee coherence of the
statistics produced
(c) in a coincidence or
overlap in the target
population
the coordination of registers,
samples, surveys and operating
procedures must be observed
to optimize the use of resources

Integration of agricultural statistics
Strategy -
emphasis to lack of coordination among
institutions
operating integration
This presentation:
PART 1 -
Thematic integration
PART 2 -
Pratical integration: register infrastructure
3
Thematic integration
Key characteristics of our main agricultural continuous surveys, in
Brazil (established, in principle, last century):
• done without direct inquiries to the producer
(commission of informants )
• production oriented (few variables)
Integration done by national accounts:
• Agriculture Census  base-year
• Continuous surveys  annual data extrapolation
4
New model for business surveys
1996  suspended the economic census and instituted the Central
Corporate Register (CEMPRE) and new bases for structural survey
in industry, civil construction, commerce and services
2003  The new series of Brazilian national accounts, is referenced
by annual surveys of industry, commerce and services.
An equivalent is missing from agriculture, except with regard to the
program of censuses.
Agriculture out of “business surveys” !
5
Agriculture specificity: the strong bias of family farming!
A large part of the agricultural production depends on family units and the
income of a large number of families is basically or largely due to their
agricultural undertaking/holding
IBGE performs a widespread household survey program that will be included
in the Integrated Household Survey Framework (SIPD), centered on a
master sample.
Analytical and methodological aspects deriving from the overlapping units
(farm and household) imposes integration between agricultural surveys and
household social survey system.
Thus, direct investigation of the agricultural holding presupposes the
assembly of a widespread integrated statistical approach.
6
Operational integration
IBGE is undertaking a major transition in its infrastructure
and survey instruments.
Follows Census 2007, including Agricultural Census 2006:
• National Address List for Statistical Purposes (CNEFE);
• Frame of Enumeration Areas with Agricultural Information;
• Register of Agricultural Holdings And Farmers – Cepa
7
Instrumentalizing integration and frame
maintenance
For Demographic Census
2010, CNEFE is being
associated with digital maps
In the pilot test of an Ongoing Census
characteristics of Agricultural Holdings
are being registered
8
Frame of Enumeration Areas with
Agricultural Information
(area frame)
85,147 enumeration areas with agricultural
activity:
62,600 in rural zone ---> (98% of area of Brazil)
22,600 in urban area or rural agglomerate
Average of 61 holdings/sector
And rural enumeration area with:
Average of 151 km2 total land surface (15,000 ha)
Median of 47 km2 (< 5,000 ha) of land surface
Main characteristic: integral cover of target
population by area sampling
9
REGISTER OF AGRICULTURAL HOLDINGS AND
FARMERS – CEPA
(list frame)
Enumeration base (Agricultural Census 2006):
~5.2 million of registered agricultural holdings;
~1.2 million with complementary farmer list information (nondweller);
Integrate with Central Corporate Register (CEMPRE)

List updating
• Main source: Annual List of Employee Information and Wages
(RAIS), an administrative register run by the Ministry of Labor.
• RAIS 2008:
– 82,000 local units of agricultural activity
– 288,000 other agricultural businesses with employees
Total 369,000 agricultural production units.

Survey Model: a dual frame application
• Considering the standards of administrative registered in
Brazil, there is no possibility of doing without a an area frame
sample in the survey of the agricultural sector.
• It is necessary to overcome its limitations for a more efficient
sampling of the larger and specialized units.
strategy  split the target population
