1) Acceleration/slowdown of the year-on-year price index growth is difference between current and previous year-on-year index. It therefore depends on the change of current month-on-month index and also on the change of base – month-on-month index (growth/decrease) in the same month of the last year.
2) Actual rentals includes both newly concluded contracts and existing ones
3) Imputed rentals are excluded from the HICP.
