Dear Hannah,
Here is a response from one of our experts, Dr. Tom Pullum:
* Kenya 2008-09 survey report, page 83, table 6.3, median age at first
* marriage for women currently 25-29 is 20.2. Try to replicate.

use KEIR53FL.dta

set more off
keep if v013==3

keep v000-v012 v507-v512

describe

* afm is completed years of age at first marriage
gen afm=int((v509-v011)/12)
tab afm,m

tab afm [iweight=v005/1000000],m

* look at the cumulative %; it is 48.37 by exact age 20 and 56.12 by exact age 21.

scalar mafm=20+1*(50-48.37)/(56.12-48.37)

scalar list mafm

* The value is 20.2

* There are more automated ways to do this. If you try to do it with the cumul command,
* you must set the missing ages at marriage (i.e. not married) to some high numerical
* value sucn as 99

* Note that the median as defined by stata would be 20, an integer.
