According to UNICEF the poverty gap is defined with medians, not means. "poverty gaps –the difference between the median income of households below the poverty line and the poverty line itself." www.unicef-irc.org/publications/pdf/rc10_eng.pdf 193.188.156.18 (talk) 07:40, 10 September 2014 (UTC)

Hello,

I deleted the statement that N equals all other people under the poverty line due to the facts, that 1) my professor is convinced it is the whole population 2) the source of the Worldbank states: The poverty gap (PG) is defined as average difference between poor households’ expenditure and the poverty line. The gap is considered to be zero for everyone else. Using the same notation as before (before refers to slides above, where N is defined as the total population) 3) http://siteresources.worldbank.org/PGLP/Resources/povertymanual_ch4.pdf (Under 4.2 the PGI is explained)

Thus the article should be corrected!

The data for OECD countries is completely wrong - the 'poverty gap' referred to there is the average shortfall of a poor individual from the poverty line, while the gap as defined by this page is that gap relative to the size of the entire population. It is not possible for the income gap on this definition to be greater than the headcount ratio. Just need to multiply the the headcount ratio by the gap for the OECD countries to sort this out, don't have time to do this now though. 192.76.8.38 (talk) 09:40, 5 April 2017 (UTC)
