simply because of the difference of the literacy level between both of them.........................................................
Demograhy only composes of Birth and death ,whereas Vital Statistics studies Marriage and migration along with death and birth for any population
Crude birth rate is how many live children are born. Crude death rate is how many people die. Crude death minus crude birth is the net gain (or loss) and is called the birth rate. It represents whether or not deceased people are "replaced".
739 BC happened 739 years before the birth of Christ, and 465 AD happened 465 years after his death.
A pronatalist policy encourages couples to have more children, therefore increasing fertility and birth rates (eg. France). However the anti natalist policy attempts to reduce birth rates to decrease the country's population (eg. China)
Factors that are considered when determining a country's rate of natural increase include the birth rate, death rate, and net migration rate. The difference between the birth rate and death rate is a key indicator of natural increase, with higher birth rates and lower death rates leading to a higher natural increase. Net migration can also play a role in influencing the overall rate of natural increase in a country.
RNI stands for Rate of Natural Increase, which is a demographic term used to measure the difference between birth rate and death rate in a population. It helps understand population growth dynamics in a specific region or country.
Natural increase of a country refers to the rate at which its population grows due to the difference between births and deaths. Fertility rate, on the other hand, is a measure of the average number of children born to women in a specific population. A country's fertility rate influences its natural increase, but other factors like mortality rates also play a role.
Birthrate is the number of births per thousand of a population whereas the natural increase is the birth rate minus the deathrate
As of 2021, the country with the highest natural increase is Niger. It has a high birth rate and relatively low death rate, leading to a significant natural increase in its population.
The rate of natural increase is the net gain in population when you subtract the Death Rate from the Birth Rate.
Birth rate- death rate= natural increase rate 20.97-7.48= 13.49 13.49 is the NIR
Developing countries have high rates of natural increase as their birth rates are high, and although their death rates are also high there is usually a big gap between the two figures. Malawi's natural increase is 30 per year for every 1,000 people. This is calculated from the Birth Rate of 51 minus the Death Rate of 21 (51 - 21=30). Developed countries have both a low death rate and low birth rate, with only a small gap between the two. Norway's natural increase is 3 per year for every 1,000 (14 - 10=3).
The rate of natural increase is the net gain in population when you subtract the Death Rate from the Birth Rate.
The formula to calculate the natural increase rate is (crude birth rate-crude death rate)/10 = % natural increase.
The formula for finding the rate of natural increase is as follows: (Crude birth rate - Crude Death Rate) / 10. The result is the rate of natural increase in percentage form. For example, Paraguay's crude birth rate (28.47) - the crude death rate (4.49) is 23.98; divide that by 10 and the result is 2.39%, Paraguay's rate of natural increase.
There is no much difference between the human birth and other primates. The process is basically the same.
