Nigeria - National Literacy Survey Nigeria-2009, First Round

Forty (40) EAs will be randomly selected from the NISH MS per state
Ten (10) households will be selected in each EA
A total of 400 HHs will be selected per state
A total of 14,800 households were sampled for the survey and out of that, 14,737 were successfully interviewed.


There were no deviation from sample Designed


A total of 14,800 households were sampled for the survey and out of that, 14,737 were successfully interviewed, which gave a response rate of 99.6 per cent.
Of the total interviewed 3,681 were captured in urban and 11,055 in rural area.

The distribution represents 25 per cent and 75 per cent respectively for urban and rural areas.


The Nigeria MICS 1999 design was not self-weighting therefore the need for appropriate weighting in the estimation procedure. Using the following notations:

Ni = No. of total EAs in ith state
ni = No. of total sample EAs in ith state
Mij = No. of housing units in jth EA of ith state.
mij (=20) = No. of selected housing units in jth EA of ith state
Yijk = The observation of the k housing units in jth EA of ith state

Y = å Ni å Mij å Yijk
ni mij

Other estimates were similarly derived. The weighting thus takes care of the disproportionate allocation.
