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	20035569	This number locates the particular value within the data table; it is like an accession number in a conventional library.
Value	1,679	This is the data value itself.

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.
