This data file is provided with the ESS data to facilitate converting non-standard units into square meters. The ESS data provide both standard unit measures of land (from GPS and/or rope and compass measures) and self-reported values which may be reported in local units. The included conversion factors have not been used to convert self-reported land values into standard unit measures. The provision of these conversion factors should not be interpreted as an endorsement of these factors by the CSA or the LSMS-ISA team. Neither the CSA nor the LSMS-ISA has validated these conversion factors under the ESS program. The conversion factors were sourced primarily from a report completed by the CSA and a study on land certification in Ethiopia, and supplemented by other internal CSA sources.
