Coding the P20 – How we developed and coded the P20 Initiative

Author

Alex Miller

This background paper discusses the use of data from 99 different household surveys to create statistics for the P20 Initiative. It highlights some of the difficulties encountered, including a lack of data for some countries, variations in language, and surveys that did not systematically include questions about income or consumption, making it hard to quantify economic wellbeing. It also explains the methods developed to decode the data to draw useful conclusions from it. Lastly, the paper explores several methods for measuring poverty and shows how they can lead to drastically different results.
