GeoConvert has been updated with information derived from the November 2010 version of the National Statistics Postcode Directory (NSPD), produced by the Office for National Statistics (ONS). All previous matching and conversion information has been retained within GeoConvert for continued use.
Discussions are taking place between ESRC, ONS and the Royal Mail regarding access to updated versions of National Statistics Postcode Directories released after November 2010.
GeoConvert is an online tool with functions providing
• Postcode-related information
• Matching of a range of current and historical UK geographies
• Conversion of data between geographies
and is available at http://geoconvert.mimas.ac.uk.
In addition to the information derived from the NSPD, GeoConvert also provides a direct matching of postcodes to LSOA-level Index of Multiple Deprivation 2007 information, developed by Communities and Local Government, as well as Index of Multiple Deprivation 2004 information.
GeoConvert’s functions are based on analysis of information contained in versions of the NSPD. The NSPD and its precursors contain a wealth of useful information about the changing relationships between a wide range of the different and changing geographies used within the UK (postcodes, super output areas, wards, primary care trusts, etc, amongst around 40 others). However, in their raw state, the size of these datasets, and the complexity of the methods required to identify relationships between geographies can soak up valuable time and resources, and present a considerable deterrent to their use.
The main aims of GeoConvert are to simplify and expand the use made of the information contained in the postcode directories within the UK academic community by providing a range of commonly required functions that are quick and easy to use, and are based upon robust and consistent methods.
GeoConvert is available free of charge to members of UK academic organisations. Details of how to register in order to use GeoConvert, as well as other services provided by the ESRC Census Programme are available on the Census.ac.uk website at http://census.ac.uk/Register_start.aspx.
GeoConvert has been developed by the Census Dissemination Unit (CDU), based within Mimas at the University of Manchester. The CDU is one of the units of the ESRC Census Programme.
