    Sampling

    Sampling Procedure

    Sampling frame
    The TUS is a household based survey. Therefore, households are defined as sampling unit. The sampling frame was based on the population and household data as of the end of 2010. Excluded are the Mongolian citizens residing outside the country or in military camps, orphanages, care centers, hospitals, prisons and other correctional institutions for more than six months.

    The total sample size determined as 4,000 households or 0.5 percent of total households, representing the entire households in Mongolia. Since the survey covered 4 quarters, sample size was divided into four equal parts for four quarters.
    Sampling method
    The sampling design used a two-stage sampling method.

    1. Stage 1: The proportionate number of households for each of the 5 regions of Mongolia was determined using probability sampling method. Following this method, it was established that there should be 640 HHs from the Western region, 800 HHs from Khangai region, 640 HHs from Central region, 480 HHs from Eastern region, and 1440 HHs from Ulaanbaatar.
      The lowest administrative units, kheseg of khoroo for Ulaanbaatar, bagh of soum for aimags (provinces), were defined as primary sampling units (PSUs). In total, 400 PSUs were selected with probability proportional to size.
    2. Stage 2: After household listing of the selected PSUs was carried out by the statistical departments or divisions, 10 households were selected using systematic sampling from each PSU.
