Is inequality largely the result of the Industrial Revolution? Or, were pre-industrial incomes and life expectancies as unequal as they are today? For want of sufficient data, these questions have not yet been answered. This paper infers inequality for 14 ancient, pre-industrial societies using...

New data now allow conjectures on the levels of real and nominal incomes in the thirteen American colonies. New England was the poorest region, and the South was the richest. Colonial per capita incomes rose only very slowly, and slowly for five reasons: productivity growth was slow; population...

Thomas Piketty's monumental Capital in the Twenty-First Century has transported us to a higher understanding of historical movements in inequality. This essay ranks the promise of different paths that scholars can usefully follow from the point to which his book has guided us. The main path to...

Building what we call social tables, this paper quantifies the level and inequality of American incomes from 1774 to 1860. In 1774 the American colonies had average incomes exceeding those of the Mother Country, even when slave households are included in the aggregate. Between 1774 and 1790,...

Just how unequal were the incomes of different classes of Russians on the eve of Revolution, relative to other countries, to Russia's earlier history, and to Russia's income distribution today? Careful weighing of an eclectic data set provides provisional answers. We provide detailed income...

Building social tables in the tradition of Gregory King, we develop new estimates suggesting that between 1774 and 1800 American incomes fell in real per capita terms. The colonial South was richer than the North at the start, but was already beginning to lose its income lead by 1800. We also...

The world economy has become more unequal over the last two centuries. Since within- country inequality exhibits no ubiquitous trend, it follows that virtually all of the observed rise in world income inequality has been driven by widening gaps between nations, while almost none of it has driven...
