In humans, the birth rate is usually expressed as the number of births per 1000 people per year. The death rate as the, number of deaths per 1000 people per year. Growth rate (k) is the rate of change (increase or decrease) of a population’s size, expressed in percent per year. Growth rate is also referred to as natural increase in human populations. If organisms in the population are born faster than they die, the growth rate is more than zero, and population size increases. If organisms in the population die faster than they are born, the growth rate is less than zero, and population size decreases. If the growth rate is equal to zero, births and deaths match, and population size is stationary despite continued reproduction and death. In addition to birth and death rates, dispersal movement from one region or country to another affects local populations. There are two types of dispersal: immigration, in which individuals enter a population and increase its size, and emigration, in which individuals leave a population and decrease its size. The growth rate
