Demographic policy, age and gender differences in population migration

Another important factor that affects the birth rate is the demographic policy carried out by the state in the population sector. Usually the policy that states take in relation to the population is economic. For example: it is mutnkin that a bit of the expense that goes to the children is taken by the state, paying monthly contributions when the child is born, providing various material assistance to families with many children. For example, China is pursuing a policy of selfindulgence in order to stop the growth for the majority of its population, albeit a little bit. One of these policies prohibited young people from entering into marriage during their student years. In almost every country of the world, a certain policy is pursued in the sphere of population. But such policies can vary for different reasons. According to the UN, now the world's population increases by 85 million people a year, every 35 years the world's population increases by more than 2 times. At present, 2/3 of the world's population does not eat enough food. Accordingly. the plan to reduce the growth rate of the world's population continues to be high. Another important factor that affects the birth rate in some countries is the wide prevalence of the management of the number of children by the couple in the family. From a brief analysis of the factors that affect the birth rate and the cause, it can be concluded that there are many factors and causes that affect the birth rate, it is necessary to analyze all of the factors in explaining the birth rate and the causes of the birth rate of the world population of ahoiisi or some countries. Data on the mortality of the population iming reproduction is an important indicator in determining the level of natural growth. About this, scientists think only on the basis of archaeological data and some written monuments that have reached US. In the second half of the XVIII century, there was a lot of death among the population in almost all parts of the world. A significant reduction in mortality began in the second half of XIX asming. The decrease in mortality during this period was the result of the achievements of medical science. A significant reduction in mortality first began in Europe. By the end of the XIX century, such diseases as plague, smallpox, plague on this continent were almost completed. The decline in mortality later spread to other continents.

The loss of life as a result of congenital diseases, caused by the biology of each person and associated with heredity, is the endogen cause of death. Threeraydi in babies more likely to die as a result of this disease. Endogen death for reasons is very rare. Most of the deaths that occur among the population are caused by exogen causes. This occurs as a result of external influence on the body of a person. When we say external influence, all the environment in which a person lives is understood. The influence of the geographic environment on the mortality rate can also be through the animal world. Some animals are the source of infection and distribution of some infectious diseases. Hullas, the impact of the natural environment on the process of death among the population is great. Mankind has for centuries been obsessed with the loss of some of its properties, which negatively affects nature for themselves, or the application of measures to combat it, and for this purpose has achieved great success.

What are the main sources of harmful substances currently polluting the atmosphere?

Since the most basic maixba cars polluting the atmosphere. Checking the air of cities showed that the concentration of harmful gases when working in some of the busiest streets of the big city, in many cases, is much higher than the permissible level. Environmental protection measures for the regional use of Natural Resources and restoration of land are being developed and implemented. Using the latest scientific techniques, natural relics are being used. Also, control over the state of environmental miiliitis and its sources of pollution is being carried out^. It is necessary to talk about another negative effect of motorization on mortality among the population, which is educational. These are car accidents. Every year around 60 million car accidents occur in the Earth's sphere on average. During these same accidents, more than 500 thousand people are killed, 10 millions are injured. The mortality rate among the population is also affected by the culture achieved by different people, their living conditions. Habits such as drinking, smoking, cannabis also cause an increase in mortality among people. Thus, the level of mortality is also influenced by the sanitary culture achieved in each state by mnhim. According to statistics, death occurs more often among children under the age of 1 year. At present, a sharp reduction in mortality among young children in almost all parts of the world has been achieved. The average life expectancy of the population varies from one to another in different states. The countries with the highest average life expectancy of the population include Sweden, Norway (79 years), Japan (80), England (72), GFR, France (79) and others. As science and culture develop further, if methods of treating cancer, cardiovascular diseases are found, the longer the life expectancy, the greater the doubt. Above we got acquainted with the main elements of the process of reproduction of the population. These indicators determine the natural growth of the population in each country and district. The natural growth of the population is determined by the residual when the number of deaths from the number of births is removed within a certain period of time. Indicators of the natural growth of the population are calculated for every 1000 people. First of all, we must say that the natural growth of the population is in different parts of the world in different countries, and even in some parts of the same country in the genus. At the moment, 85 million people are added to the population of the Earth's sphere every year, or ahoK is growing by 1,2% per year. Such a rapid growth of the world's population has never been observed. Currently, 80% of the annual natural growth of the world's population corresponds to developing countries. With an average growth rate of 1,2% on the globe, it reaches 3-3,5 even 4% in most developing countries. The natural growth of the population of most developed countries is 1,0-0,5% boisa, in some developed countries this indicator is very low: 0%.
