andy, rather than moaning about something without having even clicked on the link…you could always click on the link and read it? 🙂
It’s designed to highlight poverty in the developing world.
How do you calculate all of this?
We’ve offered two possible rankings – by income and by wealth. This requires a slightly different approach for each track; we’ve also tried to achieve the right balance between usability and rigour.
For the income track, we’ve used the most recent (2008) statistics from the World Bank, based on household surveys. Here we rank you against the entire world population at the time of the surveys, estimated at 6.69 billion people.
For the wealth track, we’ve primarily relied on 2012 estimates from Credit Suisse, who have focussed on the adult population of the world, estimated as 4.59 billion people.
For currency conversion we use Purchasing Power Parity Dollars (PPP$) in order to take into account the difference in cost of living between countries; PPP$ are also less susceptible to short term fluctuations.
After calculating the distribution of wealth or income, we then use a statistical model to estimate your rank.
Notes on calculated statistics
For the Malaria net statistic, we used GiveWell.org – this is fully costed and takes into account administrative costs.
For international salaries, we used the Occupational Wages around the World (OWW) Database, based on data collected by the ILO, a UN agency.
We estimated the price of a 330ml can of premium-brand cola to be 0.75 USD (PPP$ take care of the rest).
We took the cost of feeding a family of four a very basic diet to be $60 per month. This statistic came from the World Food Programme (a UN agency), although there is little supporting information connected with this data point.
For working time statistics, we assume people work 1,920 hours a year (40 hours a week, 48 weeks a year). For the iPhone-only statistic (sorry Android fans), we assume you work 8 hours a day.
