Mortality modeling is one of the traditional and fundamental demographic issues. The purpose of the mortality modeling is to find relations and hidden regularities and patterns in the mortality development.
This is an introduction of a simple alternative approach which is based on cohort mortality patterns modeling. The assumption of constant change of the force of mortality between two following ages across cohorts is the fundamental base of the proposed model.
This assumption was verified on time series of Swedish data which are long enough for this purpose. It was proved that the mentioned changes of mortality between ages were really nearly constant for all the cohorts and ages used for this verification.
