The growth

**of the population**is the sum of two indicators - natural and migration**increase**. Is the difference between the current level of the demographic situation and the level of the earlier period. The length of time over which the calculation is performed is called settlement and can be short-term (from one month to several years) and long-term (5, 10, 15, 25, 100 years).2

Natural increase - the positive difference between the number of births and deaths (the number of births is greater than the number of deaths). For example, in Russia, according to the August 2009 born of 151.7 thousand people died 150,7 thousand people, so a natural increase

**of the population**amounted to a thousand people. It is believed that if the birth rate exceeds the death rate, the reproduction**of the population**expanded. If these numbers are approximately equal, simple reproduction. If the death rate exceeds the birth rate, reproduction is narrowed, there is a strong demographic decline.3

Migration (or mechanical) increase of the positive difference between the number of arrivals in a country of people from other countries and the number of departures from it citizens.

To determine the General pattern of demographic change in country coefficients of

**growth****of the population**. The rate of natural**increase**is the difference between the number of births and deaths over a period divided by the total number**of the population**. The migration**growth****of the population**is the difference between the number of arrivals to the country citizens and the number of emigrants divided by total population. Accordingly, the overall rate**of growth****of the population**is the sum of these coefficients.Note

Population growth is generally measured in percentage, so the resulting ratio is multiplied by 100. The total population is taken at the beginning of the billing period.

Useful advice

Based on the data and analysis population growth rate can predict the development of the situation in the coming periods.
