Use of Population Census to Build Agricultural Census/Survey Frame ISI SATELLITE MEETING ON AGRICULTURAL STATISTICS Maputo, Mozambique, 13-14 August 2009 Session: 5 Integration of Agricultural Statistics into National Statistics System Hiek Som Deputy Director FAO Statistics Division
Rationale • For many developing countries a large portion of agriculture is household base. This implies that one-to-one correspondence between “households” and “agricultural holding” is possible in most cases. • There exists considerable commonality between the population and housing census and the census of agriculture, e.g. same Enumeration Areas and same respondents (households) . • Standard data items of population census like • Occupation • Economic activity • Employment status are useful in identification of agricultural holder/ holding.
Population and Agriculture Censuses • As a population census almost invariably involves a complete enumeration of all areas, it provides an opportunity for identifying households involved in agricultural activities (including fisheries, aquaculture, forestry), in particular: • urban agriculture, particularly when the agricultural census is confined to rural area; • holders who reside in urban area but operate land in rural area; and • small holdings, kitchen garden and landless fisheries activities which normally remain outside the scope of an agricultural census. • About 20 countries have already used this option during the last WCA round (1996-2005), though up to varying degrees.
Options of integratingPopulation and Agriculture Censuses • sharing field materials; • conducting the two censuses as a joint field operation • collecting limited agriculture-related data in the population census; • using the population census to get a household frame for the census of agriculture (and fisheries census); • linking data from the two censuses;
Integration: How? • At the level of statistical standards: concepts and definitions • Common cartographic material for surveys • Harmonized sampling units and tabulation units (e.g. villages. districts, enumeration areas) • Establishing master sample: It will be necessary to plan in advance all agricultural surveys, and include data items in population census which provide sampling frame for follow-up surveys on agriculture, aquaculture, fishing, rural activities. • Establishing shared database, eg. CountrySTAT, or data warehouse • A Common Survey framework avoids duplication of data collection efforts and hence ensure optimum use of scarce resources.
