Recreating DHS under five mortality statistics

I'm trying to estimate U5 mortality rates in for DHS surveys in India (98,06) and Kenya (98,08), and then do sub-population analysis of child mortality in slum areas. To start, I want to recreate the DHS estimates for country level under five mortality rates.

I'm using this code in Stata and am getting close, within 1-2 people, of the published DHS rate, but not exact matches. Can anyone help me see what I am missing?

Very appreciative of any suggestions.

I've created this code for the BR (birth rate) DHS file following http://siteresources.worldbank.org/INTPAH/Resources/Publicat ions/459843-1195594469249/HealthEquityCh3.pdf and http://legacy.measuredhs.com/help/datasets/

In the code below, b3 is age (cmc), and v008 is date of survey (cmc). b5 indicates if the child is alive, and b7 indicates age at death. All ages are in months. v005 is the proxy used for sampling weight suggested by DHS, since pweights aren't available in ltable.

gen hypage=(v008-b3)
gen survivelength=.
replace survivelength=hypage
replace survivelength=b7 if b5==0
gen dead=(b5==0)

ltable survivelength dead [fw=v005] if hypage <60 , int(0,1,3,6,12,24,36,48,60) failure
