INCORRECT Interactive Figure: Battery electric vehicle (BEV / Green) ownership development in Norway from 2020 to 2022—Sankey diagram of the number of green vehicles per household in the green adopter population.
PLEASE READ: This figure has errors as a result of an inconsistency in the aggregation of data from person to household level in the vehicle ownership module of the custom-written analysis code. Specifically, the vehicle ownership status of the contact person was incorrectly attributed to all other household members. As a result, vehicle ownership was overstated for households with more than one person. All person-level data processing, analysis, and person-to-household level aggregation for other socioeconomic variables are intact and unaffected.
Note 1: This Sankey diagram illustrates the dynamic flow of the number of green vehicles (BEVs) owned per household in the green adopter population. The width of the streams corresponds to the flow rate. The pillar shows the development from 2020 to 2022 regarding the relative number of households having had 0, 1, 2, 3, 4, 5, or more green vehicles (BEVs). The height of the pillar (the outer y-axis values) shows the number of households in the green adopter population in 2020. The left side of the pillar indicates the start year, 2020, and its right side indicates the last year, 2022. As a limitation, note that this pillar only shows the green ownership development in the households registered as residents by the beginning year of the pillar, i.e. this pillar does not capture any newly registered households after 2020.
Note 2: Read the numbers on the inner edge of the Sankey diagram, depicted with split darker colors, as follows: share of households owning m green vehicle(s) in year 2020 → share of households owning n green vehicle(s) in year 2022, where m and n = 0, 1, 2, 3, 4, 5, or more green vehicles (BEVs).
