Population growth rate is determined by the number of deaths in a country divided by the number of births in a year, plus the balance of the migration into and out of a country. The growth rate of a population of a nation can be negative or positive. The population growth rate is a primary factor in helping the government determine how much to invest in resources like food and water, jobs, and infrastructure (such as hospitals and schools), to make sure there will be sufficient resources in the future.

Factors Contributing to High Growth Rates
An increase in birth rate and a decrease in death rate always increases a country's population, given that the migration rate remains low or constant. The migration rate is affected by factors such as the allocation of resources in a country, as more jobs usually result in migration into the country, while poor working conditions often result migratiion to other nations.
