Rate of increase

The growth rate shows the ratio between the base and the compared level, expressed as a percentage. This value is found in the study of the dynamics inherent in various phenomena in public life. It is precisely the method of level comparison, in which the necessary indicators are derived, that makes it possible to analyze the degree of changes in phenomena over time. These values include:

- growth rate;

- rate of growth;

- the absolute value of the increase of one percent.

The growth rate is calculated in two ways:

- with the help of 100% computation and the corresponding growth rate ;

- in the form of a ratio in percent of the absolute value of the increment to the basis that was taken to calculate the amount of growth.

Based on the above, it can be concluded that all these indicators are interrelated.

The growth rate is a value characterizing the degree of increase or decrease in the level of the phenomenon being studied. If the degree of dynamic series is reduced, then this indicator has a negative value. With an increase in the level of the analyzed social phenomenon, the growth rate is positive. If the process is unchanged, this value can be zero.

All indicators used for the analysis of dynamics are calculated either on a variable or on a permanent basis of comparable material. In this case, as a rule, the level that needs to be compared is called the reporting one, and the one with which the comparison is made is the base one. In the case when the levels of the series are analyzed with a variable basis, each subsequent values of the indicators are compared with the previous ones. Such quantities are chain. If the comparison is carried out at a constant level, then such indicators are called basic.

The rate of growth characterizes the change in an economic element within a certain time interval. The dynamics of level changes is determined both in absolute values and in percent.

To determine the generalizing characteristics of the dynamics of the phenomena being analyzed, it becomes necessary to determine the average values. The method of calculating them directly depends on the nature of the economic element being investigated. If the series of dynamics are presented in interval form, then the formula of arithmetic mean simple is applied. In the study of the moment series, the calculation of the average levels is directly dependent on the nature of the economic component.

Annual growth rates are measured as a percentage of the year. For the generalization of this indicator, the mean value is calculated . It is calculated as follows:

- Calculate the average annual growth factor with the application of the formula of the average geometric value;

- Based on the value of the obtained indicator, they get an average annual growth rate, multiplying the coefficient by one hundred percent.

The average annual growth rate is the value obtained as a result of subtraction from the growth rate of one hundred percent. The obtained value will make it possible to analyze the dynamism of the development of various interrelated phenomena over a long time period (output volumes, growth rate of the number of employees, etc.). The investigated indicator will help to determine the dynamics of the social phenomenon in different states. Also, the growth rate in the average annual calculation allows us to compare a certain event in the context of the historical period in the development of the country.

When carrying out a statistical analysis, all the elements of dynamics need to be compared together, in a complex. This condition requires implementation in connection with the inextricable links that exist between the levels, absolute and relative increments, rates of development, etc.
