Data required for constructing a Lorenz curve
The essential data needed for creating a Lorenz curve includes income levels for individuals or households. This information is critical for assessing income inequality within a population. It helps in analyzing the distribution of wealth and identifying disparities among different socioeconomic groups. Researchers must have detailed income data sorted from lowest to highest earners to plot the curve accurately. The Lorenz curve visually represents the distribution of income or wealth within a population, highlighting the concentration of resources in specific segments. It is a powerful tool for policymakers and economists to understand and address inequality issues effectively.

Method of constructing a Lorenz curve
A Lorenz curve is constructed using data on income distribution within a population. The method involves plotting cumulative proportions of income received against the cumulative proportions of the population. This curve provides insights into income inequality, with a diagonal line representing perfect equality. To construct the curve, start by ordering the population from lowest to highest income. Calculate the cumulative proportions of population and income for each individual in the data set. Graph the cumulative proportions of income received against the cumulative proportions of the population. Connect the plotted points to form the Lorenz curve. The closer the curve is to the diagonal line, the more equal the income distribution.
