Q1, b, Define the term "Population Density."
Population density is a measurement of the number of people living in an area, and it is an average number. Population density is calculated by dividing the number of people by area. Population density is usually shown as the number of people per square km.
Q2, a, Describe the population distribution in Spain.
Currently, the greatest population density is recorded in the provice or city of Madrid, roughly 605 inhabitants per square km, followed by the Basque speaking provinces, measuring 295 per square km, the Canary Islands, Catalunya, Balearic Islands and Valencian Community (all with between 200 and 100 inhabitants per square km.)
The lowest density is found in Castilla-La Mancha, Aragon, Extremadura and Castilla-Leon, with less than 30 inhabitants per square km.
As the population is distributed over an area of just over five hundred thousand square kilometres, its density stands at 76.8 inhabitants per square km, considerably lower than the rest of Europe, but typical of most MEDC's.
Q2, b, Describe the population distribution in Nigeria.
The size of its population is one of Nigeria's most significant and distinctive features. Nigeria's population is about twice the size of that of the next largest country in Africa, Egypt. Nigeria represents about 20 percent of the total population of sub-Saharan Africa. The population is unevenly distributed, however; a large percentage of the total number live within several hundred kilometres, in the city of Lagos, but the population is also dense along the northern river basin areas such as Sokoto. Population densities, especially in the southwest near Lagos and the rich agricultural regions, 400 inhabitants per square km.
In contrast, other areas of Nigeria are sparsely populated and have apparently remained so for a considerable time. This pattern of population distribution has major implications for the country's development. These sparsely populated areas are due to the fact that most of Nigeria is uninhabitable, especially in the hot and desert like interior. This leads to grouping around the coastal cities.
