treated as MCH. The nomads / gipsy / migratory people, if found in the
boundary of selected Mouza/ urban block during household listing or
enumeration, were also treated as MCH.

SAMPLE SELEGTION:

All the NCHs and MCHs were enumerated on 100 % basis and no further selection
was maOe among.such type of households. However, selection procedures adopted
for Mouzas, urban blocks and common households at various sampling stages are
given below:

First Stage:Selection of Patwar Circles

The number of patwar Circles to be.selected from each district was determined
keeping in view the number of enumerators which could be made available,
effectiv-ely trained and properly supervised, as well as the inherent variance of the
population with respect to the main data items under study'

First of all, each Mouza was given a measure of size which was the geometric mean

I
tC U of iis cultivated area a-nd numbetof households-as per Mouza lists mentioned
above. This measure of size helped to brrive at the Mouza probability of selection-
which was separately calculated. This probiibility was equal to ft/ouza measure of
size divided by totai measure of size of the district multiplied by the number of
patwar circles to be selected from the same district. Then, each Patwar circle was
assigned a probability by addition of the probability of selection of its Mouzas. The
Patwar circles falling in various Kanungo circles were arranged by their cultivated
area within the respictive Kanungo Ciicles. The Patwar Circles with a probability
higher than 0.890 were selecteO witfr certainty and sifted out from the list. The
patwar Circles having probability less than 0.020 were merged with the immediately
-non-merged
above non-certainty, Patwar circle(s) of the same Kanungo circle such
that after merger the collectivJ probability of merged Patwar Circles was greater than
0.01g. These merged Patwar bircles were retained in the list as a single unit with
their collective probability for sampling purpose'

The non-certainty Patwar Circles were reassigned a probabillty Oy repeating the
above mentioned process and more certainty Patwar Circles, if found, were again
segregated, and the process continued till no certainty Patwar Circle was detected in
the lisi. After segregating all certainty Paiwar Circles, fornon-certainty Patwar Circles
a moving .rrututiiu pr-on"Oitity was worked out and shown against each Patwar
Circle in a district. For carrying out the selection of Patwar Cir:cles in a district, a
random number over zero anO up to 0.999 was. selected. The first Patwar Circle with
probability equal to or greater than the random number was considered
"r*rr"tiu"
selected. Similarly, the second Pairsar Circle was selected by adding the number 1
to the random number; the third Patwar circle was selected by addinE 2 to the
i"nCo* nr*bur, and so on, until the predetermined-number of Patwar Circles were
selected from the district, in addition to the certainty Patwar circles.

Second Stage: $election of Mouzas
To equalize the enumeration workload in a Patwar circle, it was decided to select
two Mouza. p*, *uiu"ted Patwar Circle. The Mouzas falling in certainty and selected
Patwar circles were arranged in serpentine fashion, i.e., within the odd-numbered
Kanungos, in descending 6rder of cultivated area of the Mouzas, and withtn even
nurnbeied .Kanungos in ascending order...of cultivated area of the Mouzas' The
