According to the census definition, a farm is essentially an operating unit, not an ownership tract. Therefore, all land operated or managed by one person or partnership represents one farm. In the case of multiple tenants, the land assigned to each tenant is considered a separate farm, even though the landlord may consider the entire holding to be a single unit.","data_kind":"Census\/enumeration data [cen]","notes":"The census scope covered agricultural (crops and livestock) activities.

Namely, it included all holdings that produced and sold agricultural products worth USD 1000 or more, or that would have normally sold this amount during the 2018 calendar year.","coll_mode":["Face-to-face [f2f]"],"research_instrument":"One questionnaire was used for the census. The form was prepared by the National Agricultural Statistics Service, in cooperation with the Guam Department of Agriculture. The questionnaire covered 15 out of the 23 essential items recommended in the WCA 2020.","sources":[{"name":"","origin":"","characteristics":""}],"coll_situation":"Data for the Census of Agriculture 2018 was collected via face-to-face interviews through pen and paper personal interviews (PAPI). The census employed one project manager, one crew leader\/supervisor, and ten enumerators, who received a special training in accordance with instructions prepared by National Agricultural Statistics Service. The training included practice in interviewing and filling out the questionnaire plus detailed discussion of the enumerator's instructions. \n\n**QUALITY ASSURANCE**\nQuality checks included strict field supervision, clerical screening for farm activity, follow-up of non-respondents, keying and transmission of completed report forms, computerized editing of inconsistent and missing data, review and correction of individual records identified during the computer edit, review and correction of tabulated data, and electronic data processing. \n\nEfforts were made to measure errors associated with the adjustments done for farm operations that were on the list of farm operators but did not respond to the questionnaire. The error measurement was derived from the standard error of estimates at island level, where appropriate, and was expressed as a coefficient of variation at the island level. Every estimate has a corresponding coefficient of variation published with it.","cleaning_operations":"The keyed data from each report form was available to analysts of the National Agricultural Statistics Service in Washington, DC, via electronic media, for computer editing and analysis. The corrected data were then tabulated by the computer and reviewed by analysts. Prior to publication, tabulated totals were reviewed by analysts to identify inconsistencies and potential coverage problems. Comparisons were made with previous census data, as well as other available data. The computer system provided the capability to review up-to-date tallies of all selected data items for various sets of criteria, which included, but were not limited to, geographic levels, farm types and sales levels. Data were examined for each set of criteria, and a write-up (criticism) was produced for data that was inconsistent. When necessary, data inconsistencies were resolved by carrying out corrections to data records.\n\n**DATA PROCESSING NOTES**\nCompleted questionnaires of the Census of Agriculture 2018 for Guam were sent to the Census Bureau's National Processing Center in Jeffersonville, Indiana for data capture and scanning. Optical scanning was used to capture data from the questionnaires. Staff of the National Agricultural Statistics Service on site at the National Processing Center provided technical guidance and monitored processing activities. Each report form was reviewed and coded prior to data keying. Report forms that did not meet the census farm definition were voided. Missing information was derived using reported data for similar farms (in terms of type and size) in nearby areas. After all the report forms had been reviewed and coded, the data were keyed and subjected to a thorough computer edit."}},"data_access":{"dataset_use":{"conditions":"Access and use information is set by National Agricultural Statistics Service, Department of Agriculture: https:\/\/catalog.data.gov\/dataset\/quick-stats-agricultural-database."}}},"schematype":"survey"}
