Analysis of the dynamic monitoring data of the mobile population，2009-2018 The total number of migrant population in my country shows a trend of increased first and then decrease。2009-2015 for seven consecutive years of total flow population continued to grow，increased from 211 million in 2009 to 247 million in 2015。Subsequent，The scale of the flow of population entering the quantity adjustment period，Fall to 241 million in 2018。Seventh Population Census Data Show，The size of the flow population in 2020 reached 376 million，The proportion of flow population in the general population is as high as 26.64%，Data far exceeds expectations。Where，Inter -provincial mobile population is 125 million，The migrant population in the province is 251 million，Local、Near urbanization and short -term migration have become obvious features。The surge Bet365 lotto review in the number of flow population brings a series of challenges to grass -roots household registration management and social governance，How to build a large -scale population flow in time、Adaptation to the separation of the household、​​The supporting public service system supporting is an important issue that cannot be ignored nowadays。

　　2. The average age of the flowing population continues to rise，The scale of the mobile elderly gradually expands，The new generation of flowing population has become the main force of population flow。

Dynamic monitoring data of the nationwide population population，In recent years, the average age of the migrants in my country has continued to rise，increased from 27.3 in 2009 to 30.7 years in 2017。In the social background of the aging population，The number of elderly flowing population over 60 years of age has a significant growth rate of the population.，from 0.5%in 2013 to 3.8%in 2017。The size of the new generation of the flowing population born after 1980 continues to expand，from 51.0%in 2009 to 68.1%in 2017，It has become the main force of the migrant population。As the backbone of industrial workers and the main body of new citizens，Most new generation of flowing population returns to the countryside to return to the countryside is less likely，The rural labor force derived from this is a large number of outflows、The lack of young people's labor force has become a major problem that needs to be faced by the current rejuvenation of the countryside。In addition，The new generation of migrant population in the city's social integration、Long -term residence and survival development problems also need to be further explored。

　　3. The proportion of women's flowing population increases，The gender ratio of the flow population tends to balance。

With the continuous development of society and economy，The gender structure of the population of our country has changed greatly，More and more women participate in the population flow and actively participate in social production activities。Since 2012，The proportion of women's flow population continues to rise，To 2018 reached 48.5%of the total population population。Generally speaking，2009-2018，The gender ratio of the population population in my country always maintains a relatively stable state，Men and women's sex ratio fluctuates between 100-112。But compared with 2009，The proportion of bet365 Play online games women's flowing population in 2018 decreased slightly，Men's proportion increases slightly，The other proportion of men and women is pulled open。

　　4. The education level of the mobile population is steadily improved，Non -rural household registration and new generation of mobile population education is better。

Thanks to my country's emphasis and investment in education in recent years，The overall education level of the mobile population has gradually increased。Dynamic monitoring data of the national migrant population，The education level of the flow population is mainly in the early stage of junior high school education (the proportion of more than 40%in 2010) gradually transformed into high school education level (2015 accounting for 45.3%)，The proportion of population of the cultural level of college and above is also rising faster。Monitoring data in 2017，The average education period of the mobile population is 9.6 years，Among them, the average education period of the new generation of flowing population Bet365 app download is 10.2 years，far higher than the average education period of 8.7 years of the older generation of migrant population。

　　5. The proportion of single population in the country continues to expand，Single flowing population is decreasing and single mobile men are more than women。

my country's marriage rate has continued to decline in recent years，The divorce rate is increased slightly，It has contributed to the increase in the proportion of single population in my country year by year。As far as the single situation of the flow of population，In recent years, the single rate of male migrants in my country has always been higher than women。Men in the flow population、The change in the situation of women's single situation is basically the same，2009，Male、Single rates of female flow population are all on the rise，Among them, men's single rate in 2013 is as high as 46%，Women reach 39.6%，The subsequent single rate decreased significantly，Men's single rate in 2014 dropped to 27.4%，Women drop to 20.6%，Far below 2009 single level。，The single ratio of the mobile population in my country is still showing a decline year，Men's single rate in 2017 has fallen to 17.3%，Women's single rate is reduced to 14.2%。

　　6. The proportion of single -person flow continues to decrease，The trend of familyization flow is increasingly significant。

Seventh National Census Data Show，The average scale of family households decreased from 3.10 in 2010 to 2.62 in 2020，Reflected the development trend of small -scale family scale in my country。In this background，The flow trend of the familyization of the flow population is increasingly significant。Dynamic monitoring data of the national migrant population，The proportion of single -person flow of the flowing population decreases year by year，From 26%in 2012 to 18.4%in 2017，The proportion of the population of a mobile population has bet365 live casino games exceeded 50%since 2013，to 53.5%in 2017。Family flow trends with continuous expansion of the flow population，Reflect that the degree of social integration of the migrant population has significantly improved and the cities' tolerance、Continuous improvement of openness，This requires that the city must also be an enlarged education as soon as possible、Medical、Pension、High -quality and efficient public service systems such as housing and other public service systems provide enhanced monitoring，Provide urban function construction that is compatible with the demand -side growth in time。

　　7. The income increase in the flow population is far less than the increase in housing costs，The willingness to stay for a long time continues to decline。

The average monthly income of the mobile population increased significantly from 2009-2018，increased from 2376 yuan in 2009 to 4872 yuan in 2017，But it is still lower than the average level of 6193 yuan in the national employment in the same year。Further analysis found，The nationwide mobile population income genus coefficient rose from 0.25 in 2011 to 0.35 in 2017，Reflect that the gap between the income level of the migrant population has gradually expanded。In the past five years，Many housing prices and rent flowing into geothermal cities have doubled.，However, the income increase of the migrant population is far less than the increase in housing prices and rent。Dynamic monitoring data of the national migrant population，The average monthly income of the migrant population increased by 8.19%in 2017; the average national residential sales price of the country increased by 12.21%in the same year，Among them, the economic and developed first -tier cities such as Shanghai in 2017 in first -hand house transactions are as high as 42992 yuan/square bet365 best casino games meter，Compared with 2016, a year -on -year increase of 22.2%。The cost of life continues to increase，The mobile population with long -term staying will also decrease from 41.5%in 2015 to 36.6%in 2018，This cost consciousness is particularly prominent in big cities, especially in large cities。

　8. Permination of flowing in the province，The population flow of the township is still the main driving force。

2009-2018，The proportion of flowing population flowing across provinces occupy about half。But since 2012，The migrant population in the province includes the city、The population flow activity in the county has increased significantly。The scale of the flowing population in the province in 2020 is about 251 million，increased by about 124 million compared with 127 million in 2010，far higher than the increase of 1.16.5 billion increased from 2000 to 2010。National Census Data Display，2000、In 2010 and 2020, the migrant population of the rural city accounted for 52.2%of the total population population, respectively、63.2%and 66.3%，It indicates that the flow of the countryside is still the main driving force of population flow。It is worth noting that，The scale of the migrant population of the city increased by 35 million compared to 2010，It also has a large increase。This prompts us，When the scale of the rural population shrinks in the future, it is no longer possible to provide a population to the town，The power mechanism of population migration will be deeply changed。
