Cadastral survey

Definition and stakes

“ When the facts are taken into consideration, that the Ordnance Survey is a cadastral one, in other words, that one of its many objects is the measurement and definition of all existing boundaries, political, municipal, parochial or private, and a survey and valuation of property for assessments, that its maps are accepted in courts of law as authoritative on such questions, then the problem of the scales of publication is the most important one to be considered. ”

“ Because it is not always possible for the staff of the Census Bureau to know the geographic units most appropriate for classifying people and establishments in a particular census or sample survey, they must rely on the judgment of, and participation by, local, State, tribal, and other Federal officials. Consequently, it is important that these officials, as well as all data users, understand the types of geographic entities the Census Bureau uses in its data collection, tabulation, and dissemination processes. ”

“ By contrast, the PUMS files use a sample of raw data for areas of 100,000 or greater population; PUMS areas typically comprise large cities, groupings of counties, or remainders of counties. From these samples, the data users can select and manipulate specific responses to create customized decennial census tabulations in much the same way as if they had collected the information in their own census or sample survey. Strictly speaking, the PUMS microdata areas are not official geographic units, as the Census Bureau provides neither totals nor summary information for them. ”
