There is no simple formula for population growth. Some of the factors that you need to take account of are: Emigration rates Immigration rates Demographics Age-specific fertility rates Death rates
Crude rates are rates calculated and applied for the entire population disregarding any categories such as gender or age. E.g. crude birth rate calculates the total number of births in a year over the total population including men, women and all children (provided they were not born that year).Specific rates are rates calculated considering categories or subgroups. E.g. birth rate calculates the total number of births in a year over the total number of women of child-bearing age.
They both have a 100% death rate (we all die sooner or later). However, until well into retirement ages, the death rate of male in a given age group will be higher than that for females. Early in life it is due to a larger rate of accidents and violent deaths, later due to higher rates of heart disease.
