Which is the period indicator and which is the time point indicator, the population number and the n

The number of births is a time indicator.

Period index: also known as the number of periods, it is an index that reflects the cumulative total level of the overall phenomenon in a certain period. It is the general result of the development process of the socio-economic phenomenon as a whole over a period of time. For example, the total industrial output value, the number of births, the total salary, etc. in a certain period.

Peculiarity. 1. The index values in different periods are additive, and the sum represents the overall development level of the phenomenon over a longer period of time. For example, adding 12 months of steel production in a year gives you the steel production for the whole year.

2. The size of the index value of the period is directly related to the length of the period included, in general, the longer the inclusion period, the larger the index value, and the shorter the period, the smaller the index value.

3. The value of the period indicator is the result of continuous registration and accumulation. For example, monthly production is calculated by registering daily production and accumulating, while annual production is accumulated over 12 months.

The population is a point-in-time indicator.

Point-in-time indicators are aggregate indicators that reflect the status of socio-economic phenomena at a certain time or at a certain point in time. It is not additive, and the size of the indicator value is independent of the length of the interval between the registration time, and the indicator value is counted intermittently. For example, the population of a certain area, the inventory of goods of a commercial enterprise and other indicators.

Peculiarity. 1. The index values at different time points are not additive, that is, they do not have practical significance after addition.

2. The numerical size of the time-point indicator is not directly related to the length of its time interval.

3. The value of the time-point indicator is counted intermittently, because it is impossible to register the quantity at each time point, usually once in a while.

The number of people refers to the coordinates of the point, while the number of births is the indicator of the period.

Because the number of births cannot be a number at a certain time, it requires a process, and the number of people changes from time to time, if it is a certain period, it can only be said to be the average population! Generally speaking, it is a point indicator that is always changing, and a segment indicator that requires a process.

Answer: Select B's total population

The era indicator reflects the cumulative total level of the overall phenomenon in a certain period, so only the total population of b in these four options is an indicator of the total level.

The point-in-time indicator is the total amount at a certain time, reflecting the performance of the quantitative state that has existed and changes frequently at a specific time, and its basic characteristics are:

First, the value of the indicator does not strictly change over time;

Second, there is no additiveness to the indicator values. Such as population, asset occupancy, etc.

Specific performance: first, the index values of different periods are additive, while the index values of different periods of the time point indicators are not additive, that is, they have no practical significance after adding;

Second, the size of the period indicator value is directly related to the length of the period it contains, while the size of the time point indicator value is not directly related to the length of the time interval.

Thirdly, the value of the period indicator is the result of continuous registration and accumulation, while the value of the point in time indicator is counted intermittently.

The period indicator is ADEF

The point-in-time indicator is BC

The period indicator is the total amount accumulated over a period of time, and its basic characteristics are twofold: first, the value of the indicator changes strictly with the length of time; Second, the indicator values are additive. Such as output, output value, cost, profit, etc.

The time-point indicator is the total amount at a certain time, which reflects the performance of the quantitative state that has existed and changes frequently at a specific time, and its basic characteristics are: first, the value of the indicator is not strictly changed with the length of time; Second, there is no additiveness to the indicator values. Such as population, asset occupancy, etc.

a. The indicator of population distribution is population density, so it does not conform to the topic;

b. The indicator of water resources is the total average runoff over many years, so it is correct;

c. The indicator to measure the level of urbanization is the proportion of urban population in the total population, so it does not conform to the topic;

d. The index to measure the level of foreign affairs is the total amount of imports and exports The total amount of imports and exports refers to the total amount of goods actually entering and leaving China's borders, which is an important statistical indicator that reflects the total scale and level of China's foreign affairs during the reporting period, so it does not conform to the topic

Therefore, b

The population at the end of the year in a certain area is a point-in-time indicator, and the point-in-time index is a total index that reflects the basic core of the status of socio-economic phenomena at a certain time or at a certain point in time.

Such as the first basic unit in our country.

The census shows that in 1996 there were 10,000 legal entities of various types and 10,000 industrial activity units in China, which can only explain the number of basic units in China on December 31, 1996. For example, the number of people and the amount of commodity inventory are also point-in-time indicators.

Characteristics of point-in-time indicators.

1. There is no additive, the values of indicators at different points in time can be added, and even if they are added, there is no practical significance.

2. It has nothing to do with time, and the value of the time-point indicator will not be affected by the length of the interval, and there is no direct relationship between the two.

3. Intermittent counting, the time point indicator is intermittent counting, and the number of each time point will not be registered, and it is generally registered once in a while.

Hello dear, I'm glad to answer <> for you

<> total population is an indicator of the period. The total population is a period indicator that refers to statistical indicators in a certain period, such as the total population, total GDP, etc. The total population refers to the total population of a region or country in a certain period, which is measured in an annual or specific time period.

The number of births in Congchang refers to the number of people born in a period of time, usually based on annual statistics. The period indicator reflects the overall situation in a certain period, while the flow indicator reflects the specific changes in a certain period.

Summary. No. The number of births is a relative figure that reflects the number of births in a region in a given period, rather than an absolute number.

It is influenced by many factors, such as the level of socio-economic development, population policy, socio-cultural environment, etc., which affect the change in the number of births in the population. Therefore, the number of births is not an absolute indicator, but a relative indicator, which reflects the number of births in a certain region in a certain period.

No. The number of births is a relative data in Douchang, which reflects the number of births in a certain area in a certain period, rather than an absolute value. It is influenced by many factors, such as the level of socio-economic development, population policy, socio-cultural environment, etc., which affect the change in the number of births.

Therefore, the number of births is not an absolute indicator, while the number of births in a certain area is a relative indicator, which reflects the number of births in a certain area in a certain period.

I'm still a little confused, can you be more detailed?

It is not an absolute number indicator. The number of births is a relative figure that reflects the balance between the number of births in a given area and the total population in a given period. It can reflect the birth rate of a region, but it cannot reflect the absolute number of births in a region.

The reason for this is that the number of births is a relative figure that reflects the ratio of the number of births to the total population in a given region over a given period, rather than the absolute number of births. The solution to this situation is to combine other indicators, such as total population, birth rate, etc., to more accurately reflect the number of births in a region. Personal tips for doing as you go:

When analyzing the number of births in a region, it should be noted that it is only a relative data and cannot reflect the absolute number of births in a region, and it is necessary to combine other indicators, such as the total population and birth rate, to more accurately reflect the number of births in a region.

The average number of eggs (children) laid per individual per unit of time is called the birth rate; The crude birth rate is sometimes used as the number of births of all individuals constituting a population.

A completed statistical indicator using the birth rate consists of three parts: The birth rate indicates that a completed statistical indicator consists of three parts. The birth rate is a basic indicator of demographics, which is the basis for analyzing and studying the trends of population development, and is also the basis for determining many policies related to planned birth deficits, maternal and child health policies, and health care facilities.

The natural growth rate is the ratio of the natural increase in population to the average annual total number of people in a year, usually expressed in thousands. A comprehensive indicator used to illustrate the level and rate of natural population growth. Calculation method:

Birth rate = "number of births" divided by "total population" multiplied by 100%. Mortality rate = "number of deaths" divided by "total population" multiplied by 100%. Natural growth rate = "birth rate" minus "death rate".
