Understanding Population Dynamics
Population Dynamics: Definition, Impact, Factors and Complete Solutions - Population Dynamics ??? Try to pay attention to residents around your home !, At certain times, there must be those who give birth to babies and there are people who die, and others like residents who move houses to other areas and newcomers who move to our area !!!
What does that have to do with population dynamics ??? To find out, let's consider the reviews below.
Understanding Population Dynamics
Population dynamics is a change in population conditions. These changes are influenced by several things. Dynamics or changes are more likely to be a development of the population of a country or region. The population can be known through the census, registration and population surveys.
The development of a high population if not followed by balanced economic growth will result in low quality human resources. Therefore, action is needed to control population growth so that the problems that arise can be minimized.
Factors That Influence Population Dynamics
1. Birth Rate (Natalitas), is a number that shows babies born from every 1000 population per year. Infant birth rates can be divided into 3 types, namely:
The birth rate is said to be high if the birthrate is> 30 per year.
The birth rate is said to be moderate if the birthrate ranges from 20 to 30 per year.
The birth rate is said to be low if the birthrate is around less than 20 per year.
2. Mortality rate, which is a number that shows the number of deaths from every 1000 population per year. This mortality is divided into 3 types, namely:
Mortality is said to be high if the mortality rate is> 18 per year.
Mortality is said to be moderate if the mortality rate ranges from 14-18 per year.
Mortality is said to be low if the mortality rate ranges from 9-13 per year.
3. Migration of Population (Migration), i.e. a migration of people from one region to another. Migration is divided into several types, namely:
Emigration is a movement of people from one country to another.
Immigration is the entry of a population into a certain area of the country.
Urbanization is a movement of people from villages to cities.
Transmigration is a movement of people between islands in a country.
Remigration is the return of a population to the country of origin after some time in another person's country.
The impact of migration is:
The more difficult it is to get produce from the farm of origin.
Increasingly limited to employment in the area of origin.
There is no compatibility between culture and belief in the area of origin.
Natural disasters occur, such as volcanoes, floods, and earthquakes.
Factors driving migration are:
There is a hope of getting a job you want in a new place.
There is a sense of pride in being in a new place.
Opportunities for higher education.
There is an opportunity to get a better income.
The existence of an activity, place of entertainment that attracts someone's interest.
Population Growth Formula
The formula for calculating population growth is:
P = (L-M) + (I + E)
Information:
p = population growth
l = number of births
m = number of death
i = number of people coming (immigrants)
e = number of people leaving (emigrants)
