Numbers of transactions and selling times of the statistics on prices of dwellings in housing companies were corrected

Altogether 9.2 per cent more transactions of old dwellings were added to the data. The data were supplemented least for the months in the early part of the year and most for September.

Because of the correction, the numbers of transactions of old dwellings in housing companies made through real estate agents increased on the level of the whole country by

• 0.9 per cent in January

• 3.4 per cent in February

• 7.2 per cent in March

• around 11 per cent in April to August

• 14.7 per cent in September.

The data error also had an effect on the previously reported selling times of old dwellings sold through real estate agents. The selling times shortened on the monthly level by around one to nine per cent in January to August. In September, the selling times lengthened by close on one per cent.

The effect of the error on the price index and numbers of transactions of new dwellings is so low that they will not be revised.
