Regional differences in fertility in Thailand

Abstract

This thesis is concerned with an analysis of changes in fertility levels and patterns for Thailand and differences in fertility for the four regions, the North, Northeast, Central and South. The data used are the 1960 and 1970 Censuses and the birth registration data for 1975 to 1978. Some data from the Longitudinal Surveys and the Survey of Fertility in Thailand (SOFT) are used to explain these changes and regional differences in fertility. During the intercensal period 1960-70, the decline in fertility occurred in all regions except the South. The age shape of the fertility schedules for all four regions was similar during that period. However, the mean age of the fertility schedules was lower in North and South than in Northeast and Central regions. The adjusted birth registration data suggested that the decline in fertility was accelerating between 1975 and 1978. The decline occurred in all regions, especially the North and South. The regional fertility level during this period indicates that South has the higher fertility followed by Northeast, Central and North in that order. This study suggests that since the mid 1960s the age pattern of fertility for the whole country has shifted towards a younger pattern. The change in pattern is more obvious between 1975 and 1978, especially in both the North and Central Regions and the rural sectors of Thailand. The changes in fertility levels and patterns are due to changes in nuptiality patterns and contraceptive knowledge and practice.
