We have attached a Jupyter notebook with our Stata code and a pdf of the Jupyter notebook.

We have selected a sub-sample of children under age 11.

We selected on variable a_age_dv (keep if a_age_dv<11) Sample member's age at time of the interview, derived.

Number of children (kids) under 11 in wave a = 12,331; After removing missing values (drop if a_age_dv==-9).

Potential Inconsistencies Children Under 11

1.The salient examples are.'.

pidp 885684379 ; 886142027 and 68029939 appear to have errors in a_age_dv given their date of birth a_birthy
These respondents are all much older than 11 years old.

Potential Inconsistencies (all wave a)

There are 77,309 observations in a_indall.dta.

2,055 cases have different values for a_age_dv and a_dvage (age at interview and last birthday).

1. 205 cases identified if a_dvage>(a_age_dv+2) ie. age at last birthday is greater than age at interview by +2 years.

For example
pidp 68029939
a_hidp 68029923
a_pno 4
a_birthy 1993
a_intdaty_dv 2009
a_age_dv 5
a_dvage 15

2. 218 cases identified if a_dvage<(a_age_dv-2) ie. age at last birthday is lower than age at interview by -2 years.

For example
pidp 68372651
a_hidp 68372643
a_pno 2
a_birthy 1957
a_intdaty_dv 2009
a_age_dv 57
a_dvage 51

Potential Inconsistencies (i_inall)

1. In i_indall.dta 1,242 where i_age_dv is not equal to i_dvage.

pidp 68595023
i_hidp 70148816
i_pno 3
i_birthy 2003
i_intdaty_dv 2017
i_age_dv 16
i_dvage 13

Potential Inconsistencies (b_youth file)

1. In b_youth.dta 34 cases where b_age_dv is not equal to b_dvage

For example
pidp 204400535
b_hidp 206176002
b_pno 3
b_ypdoby 1999
b_intdaty_dv 2010
b_age_dv 15
b_dvag 11

Potential Inconsistencies (b_inresp file)

1. In b_indresp.dta 470 where b_age_dv is not equal to b_dvage.

For example

pidp 69059445
b_hidp 102700402
b_pno 1
b_birthy 1959
b_intdaty_dv 2010
b_age_dv 56
b_dvage 50
