Within international development greater income is assumed to lead to greater need fulfilment, which increases subjective wellbeing. The Wellbeing in Developing Countries ESRC Research Group's dataset provides an opportunity to test these relationships using measures of income, expenditure, perceived and "objective" need satisfaction and subjective wellbeing collected in Bangladesh and Thailand. The paper demonstrates that firstly, location and socio-economic status are related to both what people say they need, and the extent to which they feel they have satisfied these needs; secondly, there is a close correlation between objective and subjective need satisfaction, indicating that people's perceptions of need satisfaction are accurate; and thirdly, there is a significant positive relationship between expenditure on basic need fulfilment and subjective and objective need satisfaction.
