The Quarterly Labour Force Survey (LFS-Q1) is a household-based sample suvey conducted by the General Statistics Office.
The survey was purposed to collect the information on labor market participation from households and household members of 15 years old and above residing in Vietnam.
This is the first quarterly LFS which was conducted by GSO following the Decision No 1287/QD-TCTK by its Director General dated 10 November 2014. The survey data was collected and reported monthly by all Provincial Department of Statistics to the Departments of Population and Labor Statistics, GSO. The micro dataset which was then produced by GSO would be aggregated quarterly for the national and regional levels and yearly for the provincial level on national statistical indicators on labor, employment, unemployment and income.
The quarterly LFS survey since first quarter 2015 has incorporated ILO's recommendations in reflecting the “labour under-utilization” category in the labour market of Vietnam.

The sample size was selected ensuring the level of representation by quarter at regional level and by year at provincial level, which specifically includes 56,340 households per quarter in equivalent to 18,780 households per month.
The sample selection includes two stages as follow:
Stage 1 (selection of location): Each province composed of two categories of selected samples by urban and rural areas. At this stage, the Provincial level list of surveyed households which was the main range of samples was extracted from 20% of the samples of the Vietnam Household Living Standard Survey (VHLSS) by 1st April 2014, would be divided into two independent ranges of samples (urban and rural areas). The surveyed locations would then be selected using the statistics probability formula decided by the Department of Population and Labor Statistics, GSO.
Stage 2 (selection of households): in each selected location for survey identified from stage 1, the Provincial Department of Statistics reviewed and updated the administrative units and prepared the list of households, grouping by an upper half and a lower half of the list. With each half of this list, the Provincial Department of Statistics selected 15 households using the sample selection software provided by GSO for the VHLSS in April 2014. The data of sample households in each group were collected on a rotation basis by different periods of the quarter. The list of selected locations for each month was prepared by the Department of Population and Labor Statistics, GSO and sent to Provincial Department of Statistics for implementation.
