Document Summary
E. g. number of births per 1,000 population in 1900. Important because (crude birth rate ) - (crude death rate) = population growth. Age-specific fertility rates the birth rate for women in a given age group at a given time. Calculated for a particular time period, e. g. 1961. Is the number of children a woman would have, if she had children according to the age-specific fertility rates prevailing at that time. Similar to the way life expectancy sums up the mortality rates at a given time. Range of tfr: 2. 5 to 8 or more. 8 for ache (on the high end- perhaps because of a high calorie meat intensive. There is a big range here (2. 5-8) more variety than more developed countries today! Howell calculates that !kung rate would go with a roughly stable population size. Foraging rates were often a bit higher, perhaps giving a cushion against occasional high death rates from famine, epidemic, etc.
