Introduction
The
original expansion plan presented by TAM to the Research Design Sub-Committee
(RDSC) and the Technical Committee (TC) envisaged not only a broader coverage
(more markets) as compared to the present panel but also a deeper coverage by
covering the Less than 0.1 Mn. urban/semi-urban population stratum. After
extensive meetings with the RDSC and the TC, the total sample size for this
coverage - ~ 100% urban India was calculated at 5800 homes.
While the
ultimate aim is to get to the above coverage, feedback received by TAM
indicated that this is best done in stages.
Accordingly
the expansion has been broken into two stages, each stage emphasising a
different aspect of the expansion plan.
Stage I – Broaden coverage to ~ all states but within
the existing reporting stratum i.e Greater than 0.1 Mn. population stratum
Stage II – Deepen coverage to the Less than 0.1 Mn population
stratum for all markets covered in Stage I.
This
document :
1. Describes
the Stage I expansion plans as was arrived at after consultations with the
RDSC
2. Gives an
update on the progress of the expansion &
3. Provides an
end-user perspective on the expansion front by detailing the impact on data
analysis
a. An ~ 100% representation of urban TV owning homes in the Class I (greater than 0.1 Mn. population) strata.
b. The above coverage accounts for 31 mn TV homes – a 35% increase from the present coverage
c. Increase in sample homes from the present 3454 homes to 4555 homes – a 32% increase
d. The sample plan is designed to maximise the effective sample size. To achieve this, an extensive Sample Optimisation exercise was conducted so that the maximisation is effective whichever way the data in analysed, either from a market point-of-view (analysis across strata) or a stratum point-of-view (analysis across markets).
e. A comparison of the proposed and the present sample sizes in the metros is given below:

The name Uttar

state of Uttaranchal. Similarly Madhya Pradesh(MP) includes Chhatisgarh and
Bihar includes Jharkhand
*
PHCHP is Punjab +

While currently all non-metro markets were reported as Rest of States, these would now be reported by strata. Thus, Rest of Maharashtra can now be analysed as RoMah. 1 Mn.+ and RoMah. 0.1-1 Mn.
TAM would now be
providing a total of 29 reporting markets which is almost double the present
reporting of 15 markets

¨ The town selection procedure makes use of the Simulated Annealing technique. The process ensures that the selected towns represent their respective reporting units on the parameters of C&S % Penetration, Terrestrial Availability of DD2, and Geographic Spread by SCR control.
¨ A highlight of the selection is that TAM has ensured the sampling of all 1 Mn.+ towns.
¨ With a fixed sample size per market one could either choose
1. More samples per town (with a lesser number of towns) or
2. Lesser samples per town (with more number of towns).
The present town selection has chosen the latter line of operation. This maximises spread and representation though being operationally and financially more demanding.
