Determinants of birth-intervals in Algeria: a semi-Markov model analysis

Abstract Objectives Analyzing the dynamics and patterns of birth intervals in the Algerian population is an important issue in developing an effective population policy. In this study, we attempted to estimate the effects of socioeconomic and demographic factors on the birth spacing process. Methods Semi-Markov models were used, based on data from the Multiple Indicator Cluster Survey (MICS), where the birth histories of 13,453 infants nested within a sample of 6,958 married women were analyzed. Results The findings stated that the birth intervals depend on: (i) mothers’ educational level, whereas wider intervals have been found for highly educated women, (ii) the wealth index, as women from poor families have short birth intervals, and (iii) there was no clear difference between rural and urban areas. Conclusions Policymakers can act through these axes to develop more efficient strategies for family planning.
