Hi,

I tried to calculate the prevalence of Stunting among Nepalese children using PR file (NDHS 2011). However, my calculations resulted in different sample size than the NDHS 2011 final report (2473 Vs 2475) from the Table 11.1 of the final report of NDHS 2011. Can anyone please suggest me what should i do to get the correct number of children (2475)?

The stata codes i had used:

*Declaring Survey data
gen finalwt=hv005/1000000
svyset hv001 [pweight=finalwt], strata(hv022) vce(linearized) singleunit(missing) || hv002

* Calculation of Stunting (Height for Age)
gen HAZ=hc70
replace HAZ=. if HAZ>=9996
gen stunting=.
replace stunting=0 if HAZ ~=.
replace stunting=1 if HAZ<-200
svy: tab stunting


and it produced,


. svy: tab stunting
(running tabulate on estimation sample)

Number of strata = 25 Number of obs = 2,473
Number of PSUs = 287 Population size = 2,536.2319
Design df = 262


stunting proportion

0 .5922
1 .4078

Total 1

Key: proportion = cell proportion

Here, the total number of children included is less (2 less) than the NDHS reported, therefore it impacted on the proportion too.

Any help regarding this would be appreciated.

Sincerely,
