¹	For 2006, consumption of fuel wood and kerosene in cottages is included in the households energy consumption while this is excluded for other years. This implies that the total energy consumption becomes about 1 per cent higher, and fuel wood 5 per cent (almost 200 kWh) higher than it would have been if this not has been included for this year.
²	The income is measured in constand 2006-kroner.
