What is it when the birth rate and the death rate are the same?
Equilibrium
What is the three letter word for the death rate being the same as the birth rate?
ZPG
Using birthrate and death rate describe a situation where the population would grow?
If the birth rate were to increase and the death rate were to remain the same, the population would grow.
Birth and death rate in Uruguay?
The birth rate is around 12 per 1,000 population per year (world average is 20). Pretty much the same as the US. The death rate is 9-10 per 1,000 population per year. The highest in South America.
If an isolated population and rsquos birthrate is the same year after year why are a greater number of individuals added to the population in each successive year?
Because the birth-rate exceeds the death-rate.
What must occur in a population for it to grow?
a. The birthrate becomes higher than the death rate. b. The birthrate stays the same and the death rate increases. c. The birthrate becomes lower than the death rate. d. The birthrate and the death rate remain the same.
Must occur in a population for it to grow?

Is RNI different from NIR?
No. RNI is not different from NIR. The Rate of Natural Increase (RNI) and the Natural Increase Rate (NIR) are both the same, in which they both are defined as the percentage growth of a population in a year as the crude birth rate minus the crude death rate. So really, RNI and NIR are the same.
What is zero birth rate?
Zero birth rate occurs when babies are born as fast as other people in the same country are dying. Births = deaths = zero birth rate.
Factors influencing birth rate and fertility rate?
Birth Rate: The birth rate of a society refers to the number of births per 1,000 people in that society. This figure is expressed as the crude birth rate (CBR) and is calculated without consideration of the sex or age of the population. Death Rate: The death rate of a society is figured in the same manner but with regard to deaths rather than births and is expressed as the crude death rate (CDR). Fertility Rate: The fertility rate of a society is the average number of children which would be born by a woman during her "childbearing" years. Replacement fertility is the fertility level at which women on the average are birthing just enough children to "replace" themselves and their partners in the population.

What factors influence the birth rate and death rate of plants and animals?
Birth Rate - Changes in the position of women. More women go out to get jobs instead of being housewives or having children - Being financially stable - Adoption, no need to give birth Death Rate - Changes in attitudes towards abortion - Secularisation - Better healthcare so babies or children don't die after birth. Infant Mortality rate in 2007 was 5 deaths per 1,000 in the UK.
When is it possible for a population growth rate to be less than zero?
Zero population growthThe so-called replacement rate is about 2.2 births per fertile woman. That's what a society needs to maintain zero population growth. That "extra" 0.2 people is what's needed to account for premature deaths -- deaths that occur before procreation. Zero population occurs when the numbers of birth rate and death rate are the same/equal.
