Population density refer to
Measure of the intensity of land use, expressed as number of people per square kilometer or square mile. Also called density of population.
Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.
Population density tells you how crowded an area is, on average. It can help you figure out the resources that a certain area requires, and it can help you compare areas. You'll need to gather data about the area and population size, then plug the numbers into the population density formula: Population Density = Number of People / Land Area.

Give one example where countries with stable governments tend to have denser populations
In a span of fifteen years, the population density of Singapore increased by approximately 1.75 thousand people per square kilometre of land area, to approximately 7.87 thousand people per square kilometre. This is due to the population of Singapore increasing over the years within a very limited space.
With a population of around 5.7 million people in 2019 and a land area of approximately 720 square kilometres, Singapore was the second most densely populated country in the world, after Monaco.
