Dowry has a longstanding place in history across the world particularly before women had legal rights to property or divorce. In many countries dowry has just phased out, most Indian Subcontinent nations have some form of laws or regulation around dowry to make it illegal (India) or to control the levels (Pakistan has limits). In spite of which the practice continues.
Recent media reports and crime statistics show the current trend is for the practice of dowry across India to be growing. It seems younger generations and/or their parents are opting to include dowry in marital negotiations.
Outside the Indian Subcontinent, the indications are that the longer families are established in countries like Australia, while arranged marriages are still commonplace, dowry is less likely to be part the arrangement.
Various factors contribute to this such as: independent rights and opportunities for women, generations moving to more gender equality.
