In towns and cities, population density and development is higher along the coastal areas.
A city is an urban area. Urban areas always have a greater population density.
Some areas of the skin have a higher density of touch and other receptors so that they are more sensitive. For instance, your fingers need to have a good set of receptors so that you can feel and pick up fine things. The skin of your face needs a high density of receptors to help protect your eyes.
General sensory receptors such as light touch and temperature receptors are located over the entire surface of the body. There are no specific areas where these receptors are located.
population density means how many live in a certain area e.g. 1 square kilometre. Urban areas are built up areas (cities etc). The higher the population density the more people in an area and the more crowded the space.
Typically, cities have a much higher population density than areas in the countryside. Cities are more densely populated due to factors such as urbanization, infrastructure, and the concentration of economic opportunities, services, and amenities in a smaller geographical area. On the other hand, areas in the countryside are characterized by lower population density, more open spaces, and a slower pace of life.
Population density in urban areas typically varies depending on the city, with larger cities generally having higher population densities than smaller ones. Factors such as size, infrastructure, and geography all play a role in determining population density in urban areas. The population density is usually measured in individuals per square kilometer or square mile.
the term population density measures the amount of humans in a particular are or geographical region. It can also apply to different living organisms and smaller areas.
The Philippines has a population density of 295 persons per sqkm. This is number 42 in a list of 238 countries listed in the attached link. As an in situation, there is a higher density in urban areas.
Bacteria and other parasites are density dependent. For example, tuberculosis which is caused by a bacteria that is spread through the air when someone who is infected sneezes or coughs, and it infects a higher percentage of people in high-density cities than in rural areas.
