Population density is a measure of the number of people living in an area relative to its size. Measuring population density helps to understand the distribution of people within an area and the level of overcrowding present. It can indicate the need for additional or improved services and infrastructure in certain areas, support planning projects and initiatives, and can be used to guide decisions about a country's population policy. Additionally, population density can help understand the longer-term impacts of climate change, such as how rising sea levels might affect coastal populations. By measuring population density, governments and organizations can gain valuable insight into the needs of their constituents and make informed policy decisions in order to promote the wellbeing of the population.
