Why Does NI 195 Not Reflect the Variations In The Proportions Of Land Uses In Different Authorities?
Although the proportions of the Standard Land Uses that are present may vary widely between one authority and another, the NI195 survey does not attempt to reflect this. This is because there is at present no simple way in which those proportions of land uses, and those variations, can be measured or weighted accurately for every single authority. The use of a ‘standard basket’ of 30 sites in each of the land uses that are present in an authority is a practical alternative which enables systematic comparisons to be made between authorities – the prime requirement for a national performance indicator.
