Survey Directorate Agriculture Coordination
Integration of agricultural statistics in
perspective the case of Brazil
Flavio Pinto BolligerAgricultural Coordinator -
IBGE
ISI Satellite Meeting on Agricultural Statistics,
Maputo Mozambique, 13 to 14 August 2009
Session 5 Integration of Sampling Frames
2
Integration needs
(a) on analyzing common aspects of different
objects of investigation
guaranteed standardization of concepts
to establish mechanisms that guarantee coherence
of the statistics produced
(b) on analyzing related matters or chain
activities
the coordination of registers, samples, surveys
and operating procedures must be observed to
optimize the use of resources
(c) in a coincidence or overlap in the target
population
3
Integration of agricultural statistics
Strategy - emphasis to lack of coordination
among institutions operating

integration PART 2 - Pratical integration

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

5
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 ? thThe 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 !
6
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.
7
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

8
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

• Frame of Enumeration Areas with Agricultural
  Information (area frame)

• 85,147 sectors with agricultural activity
• 62,600 in rural zone ---gt (98 of area of
  Brazil)
• 22,600 in urban area or rural agglomerate
  
• Average of 61 holdings/sector
• And rural sectors with
• Average of 151 km2 total land surface
  (15,000 ha)?
• Mean of 47 km2 (lt 5,000 ha) of land surface
• Main characteristic integral cover of target
  population by area sampling

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
• strategy ? split the target population

• 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.
