THIS NOTE DESCRIBES THE PROCEDURES USED IN DETERMINING DYNAMOD II AGE TRANSITION MATRICES. A SEPARATE MATRIX FOR EACH SEX-RACE GROUP IS DEVELOPED. THESE MATRICES WILL BE USED AS AN AID IN ESTIMATING THE TRANSITION PROBABILITIES IN THE LARGER DYNAMOD II MATRIX RELATING AGE TO OCCUPATIONAL CATEGORIES. THREE STEPS WERE USED IN THE PROCEDURE--(1) TAKING THE RECIPROCAL OF THE NUMBER OF SINGLE YEARS OF AGE WITHIN THE SELECTED DYNAMOD II AGE INTERVALS, (2) TAKING MORTALITY RATES INTO ACCOUNT, AND (3) CYCLING THE 1960 POPULATION THROUGH THE MATRICES TO YIELD POPULATION ESTIMATES FOR SEVERAL YEARS.
