Hi Trevor,
I used the code you given to calculate exclusive breastfeeding by using Bangladesh Demographic and Health survey 2014 data. I used the KR file. However, by using these code I found only 13.9% exclusive breastfeeding. In BDHS 2014 report this percentage is 55%. Can you help me to calculate the percentage reported in BDHS report?. Here the code i used .

use BDKR70FL.DTA

* Last child in the last 2 years living with mother
* age in months
gen age = v008-b3
* drop if too old or not alive
keep if age<24 & b5==1
* recode age into groups
recode age (0/1=1 "0-1")(2/3=2 "2-3")(4/5=3 "4-5")(6/8=4 "6-8")(9/11=5 "9-11") ///
(12/17=6 "12-17")(18/23=7 "18-23")(24/59=.), gen(child_age)
* tab of all living children born in the last 2 years
tab child_age
tab child_age [iw=v005/1000000]

* keep only those children living with mother ...
keep if b9==0
* ... and keep the last born of those
drop if _n > 0 & caseid == caseid[_n-1]
* check the deonimnator
tab child_age
tab child_age [iw=v005/1000000]

* breastfeeding status.

gen water=0
gen liquids=0
gen milk=0
gen solids=0
gen breast=0

* Water
replace water=1 if (v409>=1 & v409<=7)

* Other non-milk liquids
* check for country specific liquids
foreach xvar of varlist v409a v410 v410a v412c v413* {
replace liquids=1 if `xvar'>=1 & `xvar'<=7
}

* Powdered or tinned milk, formula, fresh milk
foreach xvar of varlist v411 v411a v412 {
replace milk=1 if `xvar'>=1 & `xvar'<=7
}

* Solid food
* check for country specific foods
foreach xvar of varlist v412a v412b v414* {
replace solids=1 if `xvar'>=1 & `xvar'<=7
}

* Still breastfeeding
replace breast=1 if m4==95

tab1 water liquids milk solids breast

* Generate column variable used in table 11.3
gen feeding=1
replace feeding=2 if water==1
replace feeding=3 if liquids==1
replace feeding=4 if milk==1
replace feeding=5 if solids==1
replace feeding=0 if breast==0
tab feeding,m
