We estimate the level and distribution of global household wealth. The levels of assets and debts for 39 countries are measured using household balance sheet and survey data centred on the year 2000. The determinants of mean financial assets, non-financial assets, and liabilities are studied empirically, and the results used to estimate average wealth holdings for countries lacking direct evidence. Data on the pattern of household distribution of wealth are assembled for 20 countries, which together account for 59 per cent of the global population and 75 per cent of global wealth. The observed relation between wealth and income distribution in these 20 countries allows estimates of wealth inequality to be produced for many other nations. Combining the figures for individual countries reveals that net worth averaged US$44,024 per adult in PPP terms across the globe. Wealth of US$8,635 was needed to be in the top half of the global distribution, and US$518,364 to be in the top one per cent. The top 10 per cent owned 71 per cent of world wealth, and the Gini coefficient for the global distribution of wealth is estimated to be 0.802, indicating greater inequality than that observed in the global distribution of consumption or income.

There has been much recent research on the world distribution of income, but also growing recognition of the importance of other contributions to well‐being, including those of household wealth. Wealth is important in providing security and opportunity, particularly in poorer countries that lack full social safety nets and adequate facilities for borrowing and lending. This chapter finds, however, that it is precisely in the latter countries that household wealth is the lowest, both in absolute and relative terms. Globally, wealth is more concentrated than income, on both an individual and a national basis. Roughly 30 per cent of world wealth is found in each of North America, Europe, and the rich Asian‐Pacific countries. These areas account for virtually all world's top 1% of wealth holders. On an official exchange‐rate basis, India accounts for about a quarter of the adults in the bottom three global wealth deciles, while China provides about a third of those in the fourth to eighth deciles. If current growth trends continue, India, China, and the transition countries will move up in the global distribution, and the lower deciles will be increasingly dominated by countries in Africa, Latin American, and poor parts of the Asian‐Pacific region. Thus wealth may continue to be lowest in areas where it is needed the most.
