Abstract

In this
study, it is aimed to determine the socioeconomic factors that affect the first
birth decision of women using the tied hazard models. In this context, the
effect of woman’s age, education level, disability status, household size and
income on the first birth decision are determined applying semi-parametric
Efron, Breslow and Exact approximations of tied hazard models on the Turkstat
2015 Household Budget Survey data because of the frequency of tied observations
in the data set. In the analyzes, Efron approximation produced more consistent
results. In addition, it is concluded that the most important factors in the
first birth decision are disability status of the woman, age and her
educational level.

İlk Doğum Kararının Sosyoekonomik Belirleyicileri: Eş Zamanlı Hazard Modelleri

Abstract

Bu çalışmada kadınların ilk doğum
kararını etkileyen sosyoekonomik faktörlerin eş zamanlı hazard modelleri
yardımıyla belirlenmesi amaçlanmıştır. Bu bağlamda TÜİK 2015 Hanehalkı Bütçe
Anketi verileri kullanılarak yarı parametrik orantılı hazard modelleri çerçevesinde
kişinin ve eşinin yaşı, eğitim seviyesi, engellilik durumu ile hanehalkı
büyüklüğü ve kadının gelirinin ilk doğum kararı üzerindeki etkileri tespit
edilmiştir. Yapılan analizde veri setindeki eş zamanlı gözlemlere rastlanılması
nedeniyle Efron, Breslow ve Kesin hazard yakınsamaları kullanılmıştır. Efron
orantılı hazard model yakınsamasının daha tutarlı sonuçlar verdiği görülmüştür.
Ayrıca ilk doğum kararının ertelenmesinde en önemli etkenlerin sırasıyla
kadının engel durumu, yaşı ve eğitim durumu olduğu sonucuna ulaşılmıştır.
