สรุป	Aggregative parish register analysis is the foundational technique of English historical demography, compiling the simple monthly and annual counts of baptisms, marriages and burials recorded in parish registers into continuous long-run series. Unlike family reconstitution, it does not identify individuals; it treats the registers as a barometer of the community's vital pulse. By assembling such counts from hundreds of parishes, Wrigley and Schofield built national series stretching back to 1538, the year English parochial registration began. From the relation between baptisms and burials one infers natural increase or decline; sharp spikes in burials betray mortality crises from famine or epidemic; the monthly distribution of events exposes the seasonality of marriage, conception and death. The method is comparatively economical, scalable across many parishes, and supplies the raw input series that inverse projection later transforms into full reconstructions of population size and structure.	Price history reconstruction is the foundational empirical craft of assembling long, continuous series of commodity prices and wages from the scattered archival record—account books of hospitals, colleges and monasteries, official market price postings known in France as mercuriales, customs and tithe records, and merchants' ledgers. Institutionalised by the International Scientific Committee on Price History in the interwar years, with William Beveridge, Earl Hamilton and N. W. Posthumus assembling national series, and given analytical depth by Ernest Labrousse's study of the conjuncture of the French Old Regime, the method turns raw quotations into standardised, spliced and weighted price indices. These series are the bedrock on which real-wage analysis, monetary history, and the study of economic crises all rest. Labrousse's anatomy of the cyclical movement of grain prices—and its role in the coming of the French Revolution—showed how price history could illuminate not just secular trends but the short-run conjunctures that shaped social and political upheaval.
