It depends on country..please mention country name..
(Births per unit of time - deaths per unit of time)/unit of time. For example, if the city of Anabru had 100 births and 70deaths in a year, the population growth rate would be 30 per year. If the population of Anabru were 10,000 at the beginning of the year, in percent, the growth rate would be 30/10,000 x 100% = 0.3%
