A field study was carried out in 1978 to assess differences and similarities in marriage practices between rural and urban families in northern Taiwan. One thousand, two hundred and twenty-eight questionnaires were analyzed to determine attitudes about mate selection, parent’s attitudes toward their children’s marriage, attitude toward marriage as a family affair, and age at first marriage. Significant differences between the attitudes of rural inhabitants and urban inhabitants were found. Rural residents maintained more traditional chinese values and customs than the urban residents. While the majority of rural families and strong parental influence in mate selection, the urban families did not. However, both rural and urban respondents considered marriage as a major family affair. The age of marriage for both males and females was older in the urban areas in comparison to the rural areas. Analysis of data also showed that higher education .levels tend to raise age at first marriage for both sexes in urban and rural areas. This trend, however, was particularly strong among the urban male respondents. The information presented in this research report provides insight into the effects of industrialization and urbanization on the social fabric of contemporary Taiwan. The differences in marriage practices between urban.and rural families has important implication for development of family planning practices and other social programs.
