Index of Deprivation

Volume 475: debated on Tuesday 29 April 2008

To ask the Secretary of State for Communities and Local Government (1) if she will place in the Library copies of the original datasets used to calculate the geographical barriers sub-domain in the English Indices of Deprivation 2007, including data for each lower layer super output area for (a) road distance to a GP surgery, (b) road distance to a general store or supermarket, (c) road distance to a primary school and (d) road distance to a post office or sub post office; (202620)

(2) if she will place in the Library a copy of the dataset of difficulty of access to owner-occupation used to compile the Index of Deprivation 2007, including data for each lower layer super output area.

The Department is seeking the relevant permissions to enable us to publish the underlying indicators of the Index of Multiple Deprivation 2007 at Lower Super Output Area level, including those in the geographical barriers sub-domain. I will place a copy of these indicators in the Library of the House.

To ask the Secretary of State for Communities and Local Government what changes were made to the methodology of the Index of Deprivation in (a) 2000, (b) 2004 and (c) 2007 in relation to the manner in which the geographical barriers sub-domain was calculated. (202629)

The Index of Multiple Deprivation 2000 (IMD 2000) is a ward level measure of multiple deprivation. For the geographical access sub-domain, average distance travelled to each service was calculated as the average distance that claimants in a particular ward would have to travel to that service, as the crow flies. The distances to post offices, doctors' surgeries and food shops were computed for claimants of means tested out-of-work benefits, while the distance to primary schools was computed for all children aged 5 to 8.

The same four indicators were used in the IMD 2004 and 2007. However both these indices are based on Lower Super Output Area (LSOA) geography, rather than ward geography. The measurement of distance changed from ;as the crow flies' to measuring road distance, to each service. The distances were measured to the nearest 10 metres. In 2004 and 2007 distance was measured for all people rather than just for people claiming out-of-work benefits. In the case of primary schools, the population used is the relevant child population.
