Document Summary

Population geography involved demography and in a geographical perspective. Spatial analysis in relation to environmental variation. Demography: statistical study of population. Mortality: deaths in a population. Migration: permanently changing residence from one geographic location to another. Basic demographic equation: fp = sp + b d + i o. Fp = #inal population. B = births during period. D = deaths during period. I = in migration during period. O = out migration during period. Rate: frequency of occurrence e. g. divorce ate. Cohort: date related to population group e. g. 5 year olds. Total- fertility rate (tfr): number of births per woman: (15- 44 years old) 2. 1 needed for replacement. Crude death rate (cdr): (per 1000) Infant mortality rate: deaths age 1 year or less/1000 live births. The amount of time required to double the number of a growing phenomena. We calculate the doubling time: t2 = 70 / % growth per unit time.
