Document Summary
Study of vital statistics (rate of births and deaths) of a population and how they change over time. Death and birth rates are important to demographers. I(cid:374) ter(cid:373)s of ge(cid:374)e flo(cid:449), the i(cid:373)(cid:373)igratio(cid:374) a(cid:374)d e(cid:373)igratio(cid:374) is(cid:374)"t for seasonal migration to cope with winter. Summarizes probability that an individual will survive and reproduce in a given year in the lifetime. Basically an age specific summary of the survival pattern of a population. Made by following the fate of the cohort. A(cid:448)erage ti(cid:373)e bet(cid:449)ee(cid:374) (cid:373)other"s first offspri(cid:374)g a(cid:374)d her daughter"s first offspring. Key component of a life table; proportion of offspring produced that survive to a particular age. For analyzing, biologics create a graph called survivorship curve. Important because it pinpoints the age when the organism had low survivor ship. Number alive at that age/ number alive at 0 years. Number of female offspring produced by each female in the population.
