PREMCHAND DOMMARAJUNON-MARRIAGE AND DIVORCE are becoming increasingly common in many parts of Asia. In East Asia, with the exception of China, marriage rates have fallen and divorce rates briefly reached levels as high as those seen in OECD countries (Dommaraju and Jones 2011). In Southeast Asia, too, marital dissolution through divorce or separation is rising (ibid.). In China, where marriage rates have not declined to the levels seen in other East Asian countries, divorce rates have tripled or quadrupled over the last two decades (Lu and Wang 2014). The major exception to this trend in Asia is South Asia, where marriage continues to be nearly universal and relatively early and divorce is relatively uncommon.In India, the focus of this article, despite wide social changes over the last three decades, marriage is still predominately caste endogamous, universal, and early and involves active participation of family and kin in spouse selection. Although changes have occurred in many aspects of the marriage system including marriage age and spouse selection (Allendorf 2013; Andrist, Banerji, and Desai 2013; Desai and Andrist 2010; Prakash and Singh 2013), these changes have not radically transformed the institution of marriage. While much is known about changes in marriage formation in India, there has been little socio-demographic research on marital dissolution. With the notable exception of Bose and South's (2003) article on son preference and marital dissolution, there has been no major quantitative study on divorce in India.This article has three broad objectives. First, it presents nationally representative estimates of prevalence, trends, and variations in divorce and separation. Media reports with headlines such as "The great Indian wedding is succumbing to the great Indian divorce" 1 have proclaimed dramatic increases in divorce and separation in India. These reports are, however, based on partial and incomplete data and non-rigorous analyses. Besides media reports there are scattered ethnographic data that by their nature are not generalizable, and quantitative information on divorce and separation is lacking. The estimates presented here provide a firmer quantitative basis for identifying trends and variations in marital stability by region, religion, family composition, and education.Second, the article examines how marriage stability is affected by broader changes in the social-cultural milieu and by specific changes in the marriage system.
