Derivation
Annex 3 of the survey report provides a detailed description of the calculation of the remotness index.
Questions 64 to 79 in Section 1C of the S1 (head teacher) questionnaire give measures of each school's access to 16 commonly-used 'facilities' (such as a police station and a bank). The survey asks the respondent for estimates of three measures of each facility's remoteness from the school: the distance from the school to the facility, the travel time to the facility, and the mode of transport required. A single index of remoteness is constructed for each school, which takes all of these measures into account.
