Convergence debate has been an important topic of economic growth literature. This article aims to investigate convergence at assorted level of disaggregation among a sample of almost 60 countries. It has tested absolute and conditional convergence hypotheses for a set of developed and developing countries by applying pooled least square methodology. The results suggest absolute convergence for countries having similar characteristics and conditional convergence for countries having heterogeneous structures. Disparity level for each country is also calculated with reference to average steady state income. The study has also scrutinized the role of investment, openness and population growth in accelerating the convergence process.
