Every row is indexed to the last quarter complete before the first day in office ("from" marks a start that had to move because that period had no data, or because the period cut it); Norway is measured over the same months. Levels are per cent changes, rates are differences in %; "per year" compounds levels and divides rates. Tenures with under 12 months, or under three observations, are left out. index, 2015 = 100 · Statistics Norway, price index for existing dwellings (table 07221), Oslo including Bærum, every type of dwelling, not seasonally adjusted, not adjusted for inflation, from 1992 · Oslo and Bærum (Statistics Norway's price region) data · as of Jul 2026.
