Purchasing power development
The development of a person’s purchasing power, calculated as the change in the standardised disposable income of the household related to the person, corrected for price changes. A change in (dynamic) purchasing power can be caused by all kinds of factors. The income changes due to, for instance, a general or periodic wage increase, promotion, entering (other) employment or retirement. Changes in the household composition (a child leaves the parental home, partners split up etc.) also lead to a change in income. All these changes are discounted in the dynamic purchasing power development.
