This research was conducted to explore households' overall perception of risk in pig farming and its relations to households' socioeconomic factors in Vietnam. The results reveal that meat price, epidemic diseases, and production cost are perceived as the most important sources of risk in pig farming. Supports from the government are associated with households' perception of less risk in information, market access and feed quality. Therefore, the government could have an important role to play in encouraging the growth of the pig farming sector by, for example, supporting households in contract farming, establishing information channels, and management market systems.
