Data and infomaton on rural income, livelihoods, and labour inputs is scarce in many countries. Moreover, there is no established methodology or repository for systematically organizing this data and information.
According to the metadata document, FAO has been working on computing the indicator for nine developing countries in Asia, Africa and Latin America, based on data collected from the Living Standards Measurement Study- Integrated Surveys on Agriculture (LSMS-ISA) surveys. Results have not been disseminated yet. Sources of information would be either agricultural surveys, or agricultural modules in integrated household surveys (e.g., LSMS-ISA) organized by the national statistical agencies, with the necessary support from the World Bank, FAO and other international agencies.
According to the metadata document, FAO Statistics, in collaboration with IFAD and the World Bank, are working towards the establishment of a harmonized program of Agricultural and Rural Integrated Surveys (AGRIS) that could form the basis for the collection of data on this, as well as on several other SDG indicators for the agricultural sector.
