Muhtasari	Historical inequality reconstruction estimates how unequally income was distributed in pre-industrial societies that left no household surveys, by exploiting social tables—contemporary or reconstructed enumerations of social classes with their populations and average incomes, in the tradition of Gregory King's 1688 anatomy of England. Branko Milanovic, Peter Lindert and Jeffrey Williamson developed the modern framework, computing a Gini coefficient from these grouped data and then placing it in context with two further concepts. The inequality possibility frontier defines the maximum inequality a society could sustain once everyone must receive at least subsistence; because poor societies have little surplus above subsistence to redistribute upward, their feasible inequality is constrained. The extraction ratio—actual inequality divided by this maximum—measures how fully the elite extracted the available surplus. Together these tools let historians compare not just raw inequality but the rapacity of ruling classes across societies of vastly different average income.	Historical national accounting is the systematic reconstruction of a country's gross domestic product and its components for periods that predate official statistical offices. Where modern statisticians collect contemporaneous surveys, the historical accountant must assemble output from surviving fragments: tithe records, customs ledgers, probate inventories, guild accounts, harvest yields, and wage books. The method adapts the conventional output, income, and expenditure approaches of national accounting to the constraints of incomplete archival evidence, building value-added estimates sector by sector and reconciling them into an internally consistent whole. Pioneered for Britain by Deane and Cole and refined by Maddison, Allen, and the Broadberry school, it has produced annual GDP series stretching back to the medieval period. The resulting estimates anchor virtually all quantitative debate about long-run growth, the timing of the Industrial Revolution, and the Great Divergence between Europe and Asia.
