Abstract
The primary objective of CMS is to provide permanent platform for the collection of data relevant to compute socio-economic indicators. Each round of the survey collects the same core data on household members' characteristics such as age, sex and marital status.

Sampling
Sampling Procedure
The sample design is a two-stage stratified cluster sample design, where primary sampling units are the census enumeration areas and the second stage sampling units are the households. A primary sampling unit is a cluster of households. Within each stratum, primary sampling units are selected with Probability Proportional to Size (PPS). The number of households within each primary sampling unit serves as a Measure of Size (MOS).
Let F1 = First stage sampling fraction
F1 = (nhMhi)/Mh Where nh = sample size = number of selected primary sampling units in stratum h.
Mhi = Number of households in ith selected psu of stratum h as of 2006 Population Census
Mh = Number of households in stratum h as of 2006 Population Census
Let F2 = Second stage sampling fraction
F2 = (m'hi/M'hi) Where m'hi=Number of selected households in ithpsu of stratum h.
M'hi = Number of listed households in the ithpsu of stratum h (during the Listing time)
Overall sampling fraction = F1*F2
Sampling Interval
Sampling interval within the cluster: M'hi = Households in stratum h of ithpsu from the listing.
M'hi = Sample size in the selected primary sampling units
Sampling Interval = (M'h/m'hi).
(a) Select a random number between 1 and interval that random number is the 1st selected household in the selected primary sampling unit.
(b) Add the interval to the random number to get the second selected household.
Continue the process until the desired sample size is achieved.
Sample size
The sample size was 3,800 households for the Third year of CMS (2014/2015). To ensure quality, interviewer performance was monitored by spot checking, observing interviews throughout the field work.
