About this dataset

The Poverty and Inequality Platform (PIP) is an interactive computational tool that offers users quick access to the World Bank’s estimates of poverty, inequality, and shared prosperity. PIP provides a comprehensive view of global, regional, and country-level trends for over 170 economies around the world.

Notes on our processing step for this indicator

<% if only_all_series == "All data points" %> We obtained the series for each indicator by extracting the closest observations to <<reference_years>>, respectively. The maximum distance between the year available and the year of reference is 5 years.

We have also included some exclusions for the years we could extract. We excluded the years 2020, 2021, 2022, 2023 and 2024 to avoid capturing the effects of the COVID-19 pandemic and its aftermath. We also excluded years before 1990 to avoid capturing data for countries in socialist regimes.

Additionally, for the World Bank Poverty and Inequality Platform dataset, we rank multiple matchings following this order of preference:

  1. The same welfare concept (first income, then consumption).
  2. The same reporting level (first national, then urban, then rural, then different). <%- elif only_all_series == "Only countries in all sources" %> We obtained the series for each indicator by extracting the closest observations to <<reference_years>>, respectively.

How we process data

Preparing this 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, and adding or adapting metadata such as the name or the description given to an indicator. An indicator can therefore draw on more than one source, for example when we stitch together data from different periods by different producers, or when we calculate per capita measures using population data from a second source.
