This study explored relationship between child marriage and vulnerability and shows that child marriage is a survival strategy to cope with external social, economic, health and political forces. The study was conducted in two areas of Larkana district. One area is rural that lacks basic amenities and the communities have to struggle to make ends meet. The other area is urban where people have access to many basic services and economic opportunities. The data collected from two areas shows that child marriage not only makes young girls vulnerable to domestic violence, but also deprives them of basic rights to education and decision making. Marriage during teenage also pose threat to their lives as they are likely to get pregnant and/or give birth to a child during teenage. But despite all this, child marriage is more common in rural areas because people have fewer economic opportunities, lack access to social safety nets, insurance services, are under heavy debts. They are also vulnerable to various diseases. By marrying off their girls at an early age with persons from better off families, the girls’ families get some financial gifts and also reduce economic burdens. Health vulnerability, in the form higher mortality rate, also pushes families to marry off girls at an early age because they want to ensure maximum reproductive capacity of girls (i.e. to reproduce as many children as possible during her child bearing age) as they are not sure how many of their children will survive. In contrast to rural areas, child marriage in urban areas was less common, age at marriage was higher, more girls were able to complete their education, and families had access to social safety nets, life insurance services and their average income was relatively higher.
