Description

Hi when I tabulate tnc (the number of calls from callrec dataset by ivfio and ivhio, I see that some a big portion of the successful interviews are coming from the households with 0 calls (no call, withdrawn from field). As far as I understand this should not happen. Is that normal, or am I missing something?

Many thanks,
Sait

Hi Sait,
the zero category also captures cases for whom the call record was lost. We will add a note to this effect in the online documentation of the tnc and ivtnc variables. We may review this practice in the future. In the meantime, you could recode these cases to missing.
Note that tnc is at the issue level and can vary accross issues, including be zero in one issue and a positive number in another. From your post is is not clear which data exactly you are cross-tabulating but when I looked at wave 1 linking ivtnc=zero cases to indresp I find that the total number of calls is missing for 3.5% of adult respondents (2,097 out of 59,507). I cannot jude whether that is a big proportion or not. It my be different in other waves as there are modes (telephone, web) where no calls to the respondents address are made.

Gundi,

use "X:\data\av\main\eudb\stata\a_callrec.dta", clear

. keep if a_ivtnc==0
(390,207 observations deleted)

. bys a_hidp: keep if _n==1
(74 observations deleted)

. merge 1:m a_hidp using X:\data\av\main\eudb\stata\a_indresp
(label a_hhorig already defined)
(label a_month already defined)

Result                           # of obs.
-----------------------------------------
