THREE reasons for the study of population density and distribution.
Answers
Answer:
FOLLOWING ARE THE REASONS FOR THE STUDY OF DENSITY AND DISTRIBUTION:-
1. The distribution of populations is the spread of people globally, i.e. where people live. Population density, usually 1 square kilometre, is the number of people residing in a given area and can be written as a total population/land area.
2. Population individuals can be split into one of three simple patterns: they can be spaced more or less evenly (uniform dispersion), uniformly scattered with no predictable pattern (random dispersion), or clustered into groups (clumped dispersion).
1. A term used to explain how humans are distributed around the World is population distribution. The distribution of populations across the Planet is uneven.
2. The Earth's land surface accounts for approximately 30 percent of its territory. However, humans can safely occupy just about 11 percent of the surface of the land.
3. Water quality, climate, relief (shape of land), vegetation, soils and the availability of natural resources and energy are physical factors influencing population growth.
These are some of the factors :
Physical considerations
1. Landforms and Relief
Lowland plains, flat river valleys and deltas and fertile-soil volcanic areas appear to have high densities of population. Mountainous regions tend to have low population densities with steep slopes and poor quality soil.
2. Climate and weather
Temperate regions experiencing few weather and temperature extremes tend to be more attracted than areas experiencing extremes.
3. Form and quality of soil
Areas with rich, fertile soils that allow effective agriculture tend to have higher population densities than areas with sparse populations with low quality soils.
Human factors
1) Agriculture Agriculture
There are also heavily populated areas with well-developed farming of crops or animals.
2) Secondary Business Sector
Those fields in which production has evolved tend to be heavily populated. It is worth noting that population densities may remain high even in old industrial areas in which production has declined or even closed.
3) Accessibility, Accessibility
Areas with well-developed transport networks and road, rail, shipping, canals and air connections are likely to be more heavily populated than areas that are poorly linked.
4) Political decisions (political decisions)
On population densities, government policies may have a huge effect. If governments plan to open up historically underdeveloped areas, this will happen.
