title: A further look at catholic fertility.
abstract: The purpose of this paper is to determine the extent to which suburbanization has influenced the traditional fertility differences observed between Catholics and Protestants. It is hypothesized that suburbanization has served to decrease religious differences in fertility, since in the more advanced stages of urbanism, that is, suburbanization, the Catholic population is likely to adopt the fertility patterns of the larger and more secularized society. Attention is focused on two objectives: (1) to examine selected aspects of fertility for Catholic8 and Protestants living in metropolitan areas and (2) to analyze religious differentials in fertility among residents in different parts of the metropolitan community.The data, consisting of a sample of households in six metropolitan areas in three population size classes, supported the general findings pertaining to religious differences in fertility that have been reported in the literature. Catholics had larger families, shorter average spacing between children, and longer fertility spans when compared to Protestants, even when a number of control variables were employed. Examining fertility differences between Catholics and Protestants in central city and suburban segments of large and small metropolitan areas, we found that the data indicated that marked Catholic-Protestant differences are still found in central cities. However, fertility differences between the two religious groups tended largely to disappear among suburban residents. The convergence in the fertility patterns of suburbanites is due to combined effects of higher fertility among Protestant suburban residents when compared to central city Protestants and the tendency of suburban Catholics to have fewer children than those who live in the city. The net result is convergence in suburban fertility.
