What you should know about this indicator

  • This data lets you compare incomes across deciles, or tenths of the population. The data shows the income threshold dividing each decile. The poorest decile threshold, for example, is the income level below which the poorest 10% of people in a country fall. We discuss these measures and the data in more detail on our page on economic inequality.
  • The data comes from the Luxembourg Income Study (LIS), which is based on national survey data. LIS takes the original data and harmonizes it by mapping the data onto a common set of definitions. This makes the data more comparable across countries than other sources, but at the cost of covering fewer countries. .
  • Income is measured after taxes have been paid and government benefits — such as public pensions, unemployment benefits, and social assistance — have been received.
  • The income data has been — that is, adjusted for household size. This makes living standards more comparable across households of different sizes, since people sharing a household can split costs like rent and heating. To make the adjustment, LIS uses the square root equivalence scale: it divides the total household income by the square root of the number of people in the household.
  • This data is expressed in constant international dollars to adjust for inflation and differences in living costs between countries. Read more in our article, What are international dollars?

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
