Demography Demography can be defined as scientific‚ mathematical‚ statistical study of population in reference to population density‚ population density‚ population distribution‚ population size and structure‚ population composition. The word Demography was first coined by a Greek Mathematician‚ Achelle Guillard. What means Population? Population means the total number of children‚ youths‚ adults and old people of a certain locality‚ village‚ town‚ city‚ district‚ region or a country. In

bone mineral density after menopause. Fractures are mostly found in the hip‚ spine and wrist. With that being said‚ this type of bone disease can cause ones inability to walk or even death. Fractures in the spine can cause deformity‚ back pain and height loss. Calcium is an important vitamin needed for our bones. It gives us the strength we need to do everyday activities. When there is not enough calcium in the bones it is easier for osteoporosis to be developed. Bone density‚ which is determined

Due to overpopulation‚ problems arise. Poverty is one of the problems that will be evident in cause of overpopulation. There will come a time that the population density of a certain area will skyrocket to uncontrollable values‚ which in turn the area will be prone to disasters such as fire. Fire in cities is a man-made disaster that is present since ancient times. Many people lose their home‚ thing and also their lives due to fire. The most common reasons of fire are faulty wiring of substandard

Overpopulation is not simply a function of the size or density of the population. Overpopulation can be determined using the ratio of population to available sustainable resources. If a given environment has a population of ten‚ but there is food or drinking water enough for only nine‚ then that environment is overpopulated; if the population is 100 individuals but there is enough food‚ shelter‚ and water for 200 for the indefinite future‚ then it is not. Overpopulation can result from an increase

appropriate indicator to use in order to make valid comparisons is population density (i.e.‚ population per unit of land area). Using this indicator one would find‚ for example‚ that Belgium has a very high population density‚ Pakistan is in the middle‚ and Somalia ranks very low. Of these countries‚ Belgium is not the one with the most difficulties. Nor does Somalia have the fewest. Just looking at population or population density tells us very little about a society’s problems. Within individual countries
