Can the gross domestic product per capita be used to measure human development instead of the HDI?
No. GDP per capita only reflects average national income. It tells nothing of how that income is distributed or how that income is spent - whether on
universal health, education or military expenditure. Comparing rankings on GDP per capita and the HDI can reveal much about the results of national
policy choices. For example, a country with a very high GDP per capita such as Oman, which has a relatively low level of educational attainment, can have a
lower HDI rank than, say, Uruguay, who has roughly 60% of the GDP per capita of Oman.

Commodity PricesCommodity Prices
FIRST published in 1864, with figures stretching back to 1845, The Economist's commodity-price index is probably the world's oldest regularly published price index. Since October 2001, our dollar-based industrials index has risen by 76%, fuelled by Chinese demand for raw materials and, in part, the weakness of the dollar. Yet in real terms, industrial commodity prices are a mere 30% of their value in 1845
