For more than one and a half years now the world is highly impacted by the Covid-19 pandemic. The covid-19 cases are, however, not evenly distributed across the countries; a few countries, particularly high-income countries have been hit harder than the countries of weak economic condition. The reasons for such an asymmetrical distribution are not clearly understood yet. In the present work, we have examined the unevenness of global distribution of Covid-19 incidences till 18 th June 2021 in terms of the economic condition of countries. Subsequently, we have tried to identify the main underlying factors behind unequal Covid-19 cases. Our analysis suggests that the degree of Isolation, the diffusion of coronavirus (interconnectivity), and the percentage of elderly people in the population are the main causes of the different unequal spread of Covid-19 cases in different countries. We find that the Covid-19 infected and death cases are well describe by a power law in terms of the stated parameters.
