SeutuRAMAVA contains data on lot reserve based on the reserve of legally valid city plans in the Helsinki metropolitan area. The data has been calculated for the data by district and statistical area.
NB: The latest SeutuRAMAVA data are available from 2017 onwards on a block-level basis in the material Lot reserve in the Helsinki metropolitan area by block (SeutuRAMAVA)
The statistical areas for each year are based on the statistical area division of the regional map for that year. The data on lot reserve is based on calculation rules agreed with municipalities (2011). Lot reserve data older than this has been recalculated using these new rules. Kauniainen was first included in the calculation in 2010. Data for Helsinki is missing for 2001. For missing data, statistical area boundaries are included and the data is described as missing.
