Document Summary
Life tables: life tables a detailed description of the age-specific mortality, survival and expectation of life of a population, life table example: Subscript x always denotes age (e. g. nx, lx, dx: n10 = number alive at age 10 l21 = fraction alive at age 21 d85 = deaths at age 85. Parameters: cohort survival lx lx the fraction of individuals in the initial birth cohort surviving to age x lx radix, the number to which all numbers are related. Radix starts (lx) with 1. 0000: practice table: x. Increasing life expectancy: aging populations, rising numbers of oldest-old, growing burden of non-communicable diseases, aging and population decline, changing family structure, evolving social insurance systems, emerging economic challenges. Insert radix in lx (1. 0000: compute l1 l1 = p0l0, compute l2 l2 = probability*l1, on a test, you will be given px or qx; solve for the other variables; don"t compute nx. Comparative life tables: measures of central tendency: mean, median, mode.
