Income research typically focuses on studying the distribution, trends, and determinants of people's earnings and sources of income. This can include analyzing factors such as wage levels, employment patterns, social benefits, and disparities in income among different demographic groups. Researchers in this field may use a variety of methods such as surveys, data analysis, and econometric modeling to understand the dynamics of income inequality and poverty. The findings from income research can inform public policy decisions related to taxation, social welfare programs, and economic development strategies.
