Introduction to the lorenz curve ๐Ÿ

The Lorenz curve is like a magical mirror that reflects how income is shared among people in an economy. Imagine a pizza divided into five slices - some slices are huge, and others are tiny. That's how income is distributed in some countries, and the Lorenz curve helps us see that picture

Quintiles and income ๐Ÿ•

  • 1st Quintile: The bottom 20% (smallest slice of pizza).
  • 2nd Quintile: The next 20% (a bit larger).
  • 3rd Quintile: Middle 20% (getting bigger).
  • 4th Quintile: Next to the top 20% (even larger).
  • 5th Quintile: The top 20% (the largest slice).

Plotting the lorenz curve ๐Ÿ“ˆ

  • Start with 0%: Just like starting a race, you begin at 0% for both households and income.
  • 1st Quintile (20% of households): Imagine giving the smallest slice of pizza (3.2% of the income) to the hungriest 20% of people. That's your first point.
  • 2nd Quintile (40% of households): Add the next slice, 8.4%, to the 3.2% you already gave. Now, 40% of the people have 11.6% of the pizza (second point).
  • 3rd Quintile (60% of households): Continue this process, giving the next 14.3% to reach a total of 25.9% (third point).
  • 4th Quintile (80% of households): Add another 23.0%, totaling 48.9% (fourth point).
  • 5th Quintile (100% of households): Finally, add the last 51.1% to reach 100% of the income, where every slice of the pizza has been shared.
