Since 1987, hotels and other lodging places have reported additional data on sources of receipts and number of accommodations. Censuses of manufactures, retail trade, wholesale trade, and some service industries began for 1958. The census of construction began for 1972. Reported data are for activities taking place throughout the census year. To enumerate establishments, Guam is divided into enumeration districts with each one assigned an interviewer.
Interviewers systematically canvass their districts.
A register book is used to screen out establishments that are not in scope of the economic census, not in operation during the census year, or not a mail respondent. For each establishment determined to be in scope of the censuses, enumerators fill out a questionnaire. Peddlers and other itinerant vendors without established places of business are not canvassed. A memorandum of understanding outlines the responsibilities of the Census Bureau and the Government of Guam in conducting the censuses. The Bureau provides the necessary funds, enumerating procedures, forms, manuals, and training.
