Between the year 1 and the year 1000, global population dynamics were characterized by high birth rates and relatively high death rates. While births likely exceeded deaths, leading to gradual population growth, factors such as disease, famine, and war contributed to significant mortality. Consequently, the population may have fluctuated, but overall, it was a period of slow growth due to these high mortality rates.
It increases.
( Number of infant death / number of life birth ) X 1000
The number of deaths of infants per 1000 live births.
Natural change refers to changes that occur in a population due to factors such as births and deaths, without the influence of migration. It is calculated by subtracting the number of deaths from the number of births in a given population over a specified period of time.

Zero population means that there is no growth in the number of people or animals or plants in an area. The number of deaths equal the number of births.
deaths under 1 year of age/ number of live births x 1000
The infant mortality rate (IMR) is calculated by taking the number of infant deaths (deaths of children under one year of age) during a given year and dividing it by the total number of live births in that same year. This result is then multiplied by 1,000 to express the rate per 1,000 live births. The formula is: IMR = (Number of infant deaths / Total live births) × 1,000. This rate is an important indicator of a country's health care quality and overall socio-economic conditions.
To calculate the natural increase of a population, you take the the countries' birth rate (number of live births per 1000 population per year) minus the countries' death rate (number of deaths per 1000 population per year) -- BR-DR
Visit the Department of Births,Deaths & Marriages Registration in Suva, Lautoka or Labasa for an accurate number.
Number of infant deaths / number of infant births (both in same time frame) gives you the percentage of infants that die.
That would be called a "stable" or "static" population - essentially unchanging.
