Poverty is a complex issue with no single agreed upon definition. While definitions aim to set boundaries, they are also limited and subject to criticism. Traditionally, poverty was defined by a single dimension like income or consumption, but modern definitions take a multidimensional approach considering factors like health, education and standard of living. Amartya Sen's capability approach is influential, defining poverty not just as lack of income but lack of ability to live a minimally good life. Overall, accurately defining and measuring poverty remains an ongoing debate with important implications for policymaking.
