Documentation for individual data value

Behind the Vision of Britain web site is a true data library, a collection of individual statistics each with its own metadata to tell users what it means. These metadata also control how the system visualises statistical data through graphs and maps. This is what we know about the particular data value you selected:

Attribute	Value	Meaning
Identifier	10686183	This number locates the particular value within the data table; it is like an accession number in a conventional library.
Value	24	This is the data value itself.
Date(s) covered	1951	We store dates within a date object, which can hold anything from a simple year value, for a census, to a period defined by two calendar dates.
Administrative area covered	10074230	South Cambridgeshire RD
Meaning (DDS cell reference)	OCC_ORD1951:female/XXVII	Cell within nCube N_OCC_ORD1951: Persons of Working Age by Sex & 1951 Occupational Order Dimension Variable Category 1 Sex Female 2 1951 Occupational Classification Other & Undefined Universe: All Workers
Table in census reports	EW1951OCC_M21	1951 Census of England and Wales, Occupations, Table 21 , 'Selected Occupations with Status Aggregates - abridged analysis', for 'Con divisions and sub-divisions, Urban Areas with population of less than 50,000, RD, NT'
Status	D	Derived. This usually indicates that the value was generated from raw data using the mappings defined in the DDS. They are sometimes suppressed from table listings.
Precision	GBE	Estimated by GBH project
Created by	occ_1951_ew_small	This is the name of our script which inserted this data value into the main data table. For non-derived values, this is usually done by copying data values across from our more conventional GBHDB database, and the scripts are usually named after the table in GBHDB they copy data from.

This table lists, in its "value" column, a single row from our data table. The values are mostly identifiers and codes which are given meaning by our main sub-systems, and the "meaning" column reaches into these to tell you more.
