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	19600013	This number locates the particular value within the data table; it is like an accession number in a conventional library.
Value	696	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	10027380	Clitheroe RD
Meaning (DDS cell reference)	IND_SECTOR_GEN:ag	Cell within nCube N_IND_SECTOR_GEN: Simplified Industrial Structure Dimension Variable Category 1 Industry Sector Agriculture Universe: All Workers reporting an occupation
Table in census reports	EW1951IND_M3	1951 Census of England and Wales, Industry, Table 3 , 'Industries (Orders and Selected Units) and Status Aggregates. Occupied Males and Females aged 15 and over', for '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	E	Exact
Created by	add_derived_1	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.
