usually birth and death rates are calculated based on 1000 people, not per capita (1 people), because per capita rates are very small. Nonetheless, both per capita rates are calculated by simply dividing the total number of births (or deaths) by the total population. The total population should be the one at the beginning of a specified period (or, better, an average for the entire period) whereas the births /deaths are counted for the entire period.
For example, China had an estimated population of 1,300,000,000 in January 2005. In the whole year 2005 about 17,100,000 births were expected. This corresponds to a per capita Birth Rate of 17.1 mio./1300 mio. = 0.01315
Similarly China's per capita Death Rate can be estimated to be about 0.00694, which means the Chinese population is growing overall.
Birth Rate= No. of births/average no. of population x 1000 Death Rate= No. of deaths/annual average no. of population x 1000 from:BPSHS 15 18
Death Rate is the actual rate of death where Crude Death Rate is a guess on the death rate.

The formula to calculate the natural increase rate is (crude birth rate-crude death rate)/10 = % natural increase.
Death Rate is the actual rate of death where Crude Death Rate is a guess on the death rate.
The current approximate natural increase rate of the world is about 1.14%. It can be calculated the formula, " (Crude birth rate − Crude death rate) / 10."
Subtract the crude death rate from the crude birth rate.Crude birth rate is the number of children born per one thousand people.Crude death rate is the number of people that die per one thousand people.
Population growth rate is the rate at which populations change in size over time as a fraction of the initial population. The formula used to measure growth rate is (birth rate + immigration) - (death rate + emigration).
still birth + early neonatal death per 1000 live birth
The formula for finding the rate of natural increase is as follows: (Crude birth rate - Crude Death Rate) / 10. The result is the rate of natural increase in percentage form. For example, Paraguay's crude birth rate (28.47) - the crude death rate (4.49) is 23.98; divide that by 10 and the result is 2.39%, Paraguay's rate of natural increase.
mortality rate - death rate
Doubling population rate is however long it takes for a country's population to double - but calculation wise I THINK (not sure) [ (Immigration rate - emigration rate) + (Birth rate - death rate) ]check around site for a confirmation of the formula
the birth rate is 65% and death rate is 35%
