• estimates of labor force
• statistics on access to services
• statistics on nutrition

Target population

All non-institutional households in Lao PDR

Survey period

12 months, from March 1997 to February 1998

Survey design

Survey units are households and villages. LECS used four survey instruments: a diary to record household transactions, a household questionnaire, a time use diary and a village questionnaire.  The household transactions diary was kept for one month. The time use diary covered a randomly selected 24-hour period for one randomly selected household member.

Sample design

A two-stage sampling scheme was used. At the first stage a sample of villages was selected by PPS sampling. The villages were stratified by province and within province by urban villages, rural villages with access to road and rural villages without access to road (54 strata). 25 villages were selected in each stratum. The sample of villages in each province was allocated randomly to a survey month so that each of the 12 survey months had approximately the same number of sample villages.In the second stage a systematic sample of 20 households was selected in each sample village. The selection was based on an updated list of households in the villages at the time of the survey.

Sample size

57 624 persons in 8882 households in 450 villages
