The supplemental .zip archive for this publication contains the syntax files that were used to estimate cohort and period indicators of nuptiality and fertility (SPSS files were created by using IBM SPSS Statistics, Version 20).
The GGS Wave 1 micro-datafiles for all GGS countries are available online from the GGP Data Archive (http://www.ggp-i.org/data/data-access.html). Registration is required before you can access the data. As a result, the original GGS Harmonized Datafiles are not shared here.
The syntax files allow the user/reader to replicate all different nuptiality indicators (ASFFMR, Period TFFMR, Cohort TFFMR, Period MAFFM and Cohort MAFFM) and fertility indicators (ASFR, Period TFR, Cohort TFR, Period MAC and Cohort MAC) for GGS Belgium. The code can be modified and applied to the microdata for other countries by using the information in Table 1 of the article. This table provides the user/reader with more information on the selections used for the different countries (for rates up to age 49). Note that the time periods considered for validation in Table 1 are based on rates calculated up to the age of 49 (while syntax selections are for the max. range, i.e. rates up to age 39). Also note that variable names differ between GGS countries (e.g. the max. number of partnerships, max. number of resident biological children, etc.).
1. ASFFMR & CTFFMR (GGS Belgium, Wave 1).sps
The syntax file retrospectively estimates age-specific female first marriage rates (ASFFMR), cohort total female first marriage rates (Cohort TFFMR) and cohort mean ages at female first marriage (Cohort MAFFM).
Calculation procedure for other countries: check and change the number of max. partnerships (step 1: a335y_*).
Selection of birth cohorts given year of interview (Table 1):
1) Part 1: 'SELECT IF (BIRTHY GE 1928 AND BIRTHY LE 1993)' are birth years of female respondent (min. 20 women per birth year) so that the youngest respondent turns 15 in earliest interview year;
2) Part 2: '2010' is the last interview year;
3) Part 3b: 'BIRTHY LE 1970' and 'BIRTHY LE 1960' are birth years that respondents turn resp. 40 and 50 in the last interview year.
2. ASFFMR & CTFFMR Weighted (GGS Belgium, Wave 1).sps
The syntax file retrospectively estimates weighted age-specific female first marriage rates (ASFMMR), cohort total female first marriage rates (Cohort TFFMR) and cohort mean age female first marriage rates (Cohort MAFFM).
Calculation procedure for other countries: check and change the number of max. partnerships (step 1: a335y_*).
Selection of birth cohorts given year of interview (Table 1):
1) Part 1: 'SELECT IF (BIRTHY GE 1928 AND BIRTHY LE 1993)' are birth years of female respondent (min. 20 women per birth year) so that the youngest respondent turns 15 in earliest interview year;
2) Part 2: '2010' is the last interview year;
3) Part 3b: 'BIRTHY LE 1970' and 'BIRTHY LE 1960' are birth years that respondents turn resp. 40 and 50 in the last interview year.
3. ASFFMR & PTFFMR (GGS Belgium, Wave 1).sps
The syntax file retrospectively estimates age-specific female first marriage rates (ASFFMR), period total female first marriage rates (Period TFFMR) and period mean age at female first marriage (Period MAFFM).
Calculation procedure for other countries: check and change the number of max. partnerships (step 1: a335y_*).
Selection of cohorts and validation period given year of interview (Table 1):
1) Part 1: 'SELECT IF (BIRTHY GE 1928 AND BIRTHY LE 1993)' are birth years of female respondent (min. 20 women per birth year) so that the youngest respondent turns 15 in earliest interview year;
2) Part 2: '1968 !TO 2005' (cfr. calculation rates up to age 39: earliest year period measures in Table 1 - 10);
3) Part 3: aggregate number of marriages, age-specific rates, etc. by year;
4) Part 4: '1968 !TO 2005' for the calculation of ASFFMR's + variable flip by yearly ASFFMR.
4. ASFFMR & PTFFMR Weighted (GGS Belgium, Wave 1).sps
The syntax file retrospectively estimates weighted age-specific female first marriage rates (ASFFMR), period total female first marriage rates (Period TFFMR) and period mean ages at female first marriage (Period MAFFM).
Calculation procedure for other countries: check and change the number of max. partnerships (step 1: a335y_*).
Selection of cohorts and validation period given year of interview (Table 1):
1) Part 1: 'SELECT IF (BIRTHY GE 1928 AND BIRTHY LE 1993)' are birth years of female respondent (min. 20 women per birth year) so that the youngest respondent turns 15 in earliest interview year;
2) Part 2: '1968 !TO 2005' (cfr. calculation rates up to age 39: earliest year period measures in Table 1 - 10);
3) Part 3: aggregate number of marriages, age-specific rates, etc. by year;
4) Part 4: '1968 !TO 2005' for the calculation of ASFFMR's + variable flip by yearly ASFFMR.
5. AOSFR & CTFR (GGS Belgium, Wave 1).sps
The syntax file retrospectively estimates age-order-specific fertility rates (AOSFR), cohort total fertility rates (Cohort TFR) and cohort mean ages at schildbearing (Cohort MAC).
Calculation procedure for other countries: check and change the number of max. household members (step 1: for resident biological children variables ahg3_* and for non-resident biological children variables a213_*).
AOSFR & CTFR for the selected birth cohorts (Table 1) reflect completed fertility (15-49), whereas the results for more recent birth cohorts reflect incomplete fertility.
6. AOSFR & CTFR with weights (GGS Belgium, Wave 1).sps
The syntax file retrospectively estimates weighted age-order-specific fertility rates (AOSFR), cohort total fertility rates (Cohort TFR) and cohort mean ages at childbearing (Cohort MAC).
Calculation procedure for other countries: check and change the number of max. household members (step 1: for resident biological children variables ahg3_* and for non-resident biological children variables a213_*).
OSFR & CTFR for the selected birth cohorts (Table 1) reflect completed fertility (15-49), whereas the results for more recent birth cohorts reflect incomplete fertility.
7. AOSFR & PTFR (GGS Belgium, Wave 1).sps
The syntax file retrospectively estimates age-order-specific fertility rates (AOSFR), period total fertility rates (Period TFR) and period mean ages at childbearing (Period MAC).
Calculation procedure for other countries: check and change the number of max. household members (step 1: for resident biological children variables ahg3_* and for non-resident biological children variables a213_*).

4) Part 4: '1968 !TO 2005';
5) Part 5: obtaining age-specific rates by year.
