I'm assuming it would be Population Density. My class never covered this subject greatly, but the definition is "Population density is a measurement of population per unit area or unit volume;" which sounds like what you are looking for.
Hope this helps!

M, G1, S, and G2. M is mitosis and followed by cytokinesis. S phase is the period when DNA replication occurs.
Metanephridia differ from protonephridia in that selective reabsorption of materials occurs via cells lining the tubules in protonephridia and via capillaries in metanephridia is true.
<h3>
What are the Metanephridia?</h3>
Metanephridia gather the liquid from the celomatic hollow space via a funnel-like shape known as nephrostome. The coelomic fluid enters the tubulus, water and vitamins are reabsorbed, and the metabolic waste inclusive of ammonia, urea, or uric acid is excreted.
The principal distinction among protonephridia and metanephridia is that protonephridia are a community of dead-give up tubules with out inner openings, while metanephridia are a kind of excretory glands with a ciliated funnel starting into the frame hollow space.

The population surpassed the bearing capacity and resources began to deplete that time.
This statistic doesn't really account for the impacts of immigration or emigration, which would result in much more mortality than births or an equal amount of deaths and births in these nations. As a result of this negative or zero natural population growth, or because there are an equal number of births and deaths in certain nations, immigration and emigration are not taken into account.
Only one of the 20 countries—Austria—was predicted to increase between 2006 and 2050, even when immigration was taken into account. However, the mid-2010s influx of people fleeing hostilities in the Middle East (notably Syria's civil war) and Africa may cause this prediction to be revised.
Here's another question similar to this about negative population growth rate:
