The World Bank's Living Standard Measurement Study (LSMS) was adapted for use in Guyana and administered in early 1993 as part of the Guyana Bureau of Statistics' year-long Household Income and Expenditure Survey (HIES). Because the LSMS survey was to take place at about the same time as the Household Income and Expenditure Survey (HIES), it was decided to link the two surveys. The HIES questionnaire substituted for the normal LSMS modules on income, expenditures, labor activities, household businesses, housing, durable goods, and savings. The LSMS questionnaire focused only on health, education, migration, fertility, and anthropometrics.
