Distributional Analysis Technical Annex Methodology - Data sources

The HRP “provide[s] an individual person within a household to act as a reference point for producing further derived statistics and for characterising a whole household according to characteristics of the chosen reference person”3, with the HRP either being the person in whose name the household’s accommodation is owned or rented, or the person with the highest income in the household. [...] In this case the HRP is used because their marital status is inherently connected to that of the other adults in the household, so by constructing the variable based on them the analysis very likely takes account of the whole household. [...] Ethnicity For ethnicity, the analysis uses the ethnicity of the ‘first two’ adults in the household, defined as the HRP and their partner. [...] The years used in the analysis are 2025 and 2035, where modelled EV share of the vehicle stock in these years is eight per cent and 55 per cent respectively, so the top ranked eight per cent of households are assigned to the EV group in 2025, and the top 55 per cent to the EV group in 2035. [...] The first presents the impacts of the Commission’s recommended package of interventions in the Assessment, whilst the second presents an alternative package which the Commission is required to develop and puts a relatively higher burden on households in exchange for a lower burden on government.
