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	431937	This number locates the particular value within the data table; it is like an accession number in a conventional library.
Value	267	This is the data value itself.
Date(s) covered	1821	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	10545675	North Meols SubD
Meaning (DDS cell reference)	POP_CHANGE:over_10yrs	Cell within nCube N_POP_CHANGE: Population Change Dimension Variable Category 1 Population Change Change over 10 years Universe: Change in number of Persons
Table in census reports	GB1851POP2_M[1]	1851 Census of Great Britain, Population tables 2, Table [1] , 'Population Abstract'
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	par_1851_ew	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.
