A negative growth rate indicates that the population is decreasing in size over time. This may be due to factors such as low birth rates, high death rates, emigration, or other demographic factors. It can have implications for the economy, workforce, and overall health of the population.
A negative growth rate in microbiology signifies that the population of microorganisms is decreasing over time. This can impact the overall microbial population dynamics by leading to a decline in the number of microorganisms present, potentially affecting the ecosystem and interactions within it.
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.
The biggest thing that can change a population is the availability of jobs in that are. 2 other things that can change the population of an area is what businesses are there and the crime rate.
In a population without limits, there will be an increase in the population size. For that we will use the equation (dN/dt) = 1.0 N where N is the number of individuals in the population and (dN/dt) is the rate of change in the number of the population over time.
For a population to grow, the birth rate must exceed the death rate, there must be enough resources available to support the increase in population, and factors that limit growth such as disease or predation must be controlled.

Yes, in a mathematical sense a growth rate is defined as a rate of increase in a series over time. Thus if the series is declining over time, or for a period, the growth rate is negative. In a semantic sense, it is probably better to refer to 'contraction' rather than 'negative growth', but it is not incorrect to use the latter terminology.
Much of Europe
A negative population growth exists
If the population growth rate becomes zero the population size becomes static. It stays where it was when it became zero until the rate changes. If the rate becomes negative the population would begin to shrink.
Birthrate is how many people are born, while the population growth includes the death rate as well. If the birthrate minus the death rate is positive then the population growth is +. If it is negative there is a decrease in population (the population is - ). The population growth also takes emigation and immigration into the picture.
Actually, a population has a negative growth rate when the death rate exceeds the birth rate. This means that more individuals are dying than being born, resulting in a decline in population size over time.
The population growth has been negative within the past 20 years.
Growth in population, and in growth rate, can be caused by many factors. For example, it might indicate improved health amongst citizens, such as by higher birth rate and/or increased years in life. A population growth can also be caused by immigration. Growing industries that need workers can attract new residents to a country, increasing its' population. Such growth from immigration may also result from negative factors, too. For example, persons in a country affected by war, famine or oppression may flee to another nearby country, increasing the total population in that new country.
