Anna Diofasi and Nancy Birdsall from the Center for Global Development have collated a dataset ranking countries based on their median daily income or consumption using the World Bank's PovcalNet database, based on 2011 PPPs. This dataset was then used by Hauke Hillebrandt from the Giving What We Can charity to produce this comparison of Median GDP/capita vs Mean GDP/capita, as well as a crude estimate of median household GDP. The median value ranges from the lowest, Madagascar, at $383.25, to Norway, at $21,717.50.
Unfortunately, the Google Maps visualisation on the latter page seems to be broken, so I've recreated it.
The limitations of this dataset relate not only to the availability of survey data from the World Bank - various survey years are used ranging from 1992 (Trinidad and Tobago) to 2013 - but also the varied use of consumption or income data to produce the median estimate. In addition, Hillebrandt notes that "Of course, income only gives a limited picture of a country," but reckons that the statistics are still useful to get a "general sense of the economic well-being of its people."
Both sources agree that the use of the mean GDP value is sometimes misleading - Hillebrandt states that it doesn't take into account wealth inequality, and the CGDEV notes:
Average or mean-based measures of income, such as GDP per capita, will
always be higher than the median — the value at the midpoint — of that
distribution, which is inevitably skewed to the right. So medians
convey far better the material well-being of the typical individual in
a country and have other advantages including simplicity and
durability. The simplicity helps explain why the stagnation of the
median wage is so often cited in the US press in the context of
middle-class decline as the benefits of growth go to the top. Real
median household income has been about $53,000 a year or $48 a day per
person for a family of three. That puts median income per person in
the US at only just about one-third of average income measured as GNI
