Question

помогите.....плиз задали на завтра а я не могу решить...численность населения страны в 2005 г. составила 1304 млн.человек ,в 2010 г. 1330 млн.чел.Рождаемасть в 2010г. составила 12‰, а смертность 7‰.Рассчитаете,на сколько изменилась численность населения за указаный период.чему равен естественный прирост населения в 2010г.?определите о какой стране идёт речь.с чем связано уменьшение естественного прироста населения в этой стране?

Answer 1

Изменение числености-1330-1304=26 миллионов

естественый прирост-1330*5/100=66,5 миллионов

Страна скорее всего Китай-там борятся с ростом населения,если не ошибаюсь,там демографическая зима

Answer 2

Calculation of Population Change

To calculate the change in population for the specified period, we need to subtract the population in 2005 from the population in 2010.

The population in 2005 was 1304 million people, and the population in 2010 was 1330 million people.

To find the change in population, we subtract the population in 2005 from the population in 2010:

1330 million - 1304 million = 26 million

Therefore, the population increased by 26 million people during the specified period.

Calculation of Natural Population Growth

To calculate the natural population growth, we need to find the difference between the birth rate and the death rate, and then multiply it by the total population.

The birth rate in 2010 was 12‰ (per thousand), and the death rate was 7‰ (per thousand).

To calculate the natural population growth, we subtract the death rate from the birth rate:

12‰ - 7‰ = 5‰

Next, we multiply the natural population growth rate by the total population in 2010:

5‰ * 1330 million = 6.65 million

Therefore, the natural population growth in 2010 was approximately 6.65 million people.

Identification of the Country

Unfortunately, the information provided does not specify the country in question. Without additional information, it is not possible to determine which country is being referred to.

Reasons for Decreased Natural Population Growth

The decrease in natural population growth in a country can be influenced by various factors. Some possible reasons for a decrease in natural population growth include:

1. Declining fertility rates: If the birth rate decreases significantly, it can lead to a decrease in natural population growth. This can be caused by factors such as increased access to contraception, changes in societal norms, and economic factors.

2. Increasing life expectancy: If the death rate decreases due to improvements in healthcare, nutrition, and living conditions, it can also contribute to a decrease in natural population growth.

3. Aging population: If a country has a large proportion of elderly people, it can lead to a decrease in natural population growth. This is because the number of deaths may exceed the number of births.

4. Migration: If a country experiences significant emigration or immigration, it can affect the natural population growth rate. Emigration can lead to a decrease in population, while immigration can contribute to an increase.

It is important to note that without specific information about the country in question, it is difficult to determine the exact reasons for the decrease in natural population growth.
