On May 11, the main data results of the seventh national census were officially announced, with detailed data and a large amount of information. So, how can we quickly understand and understand the key data and trends behind this census?
Based on the seventh census data released by the National Bureau of Statistics, we used Wyn Enterprise business intelligence software to create a visual chart display of this census data. Let us take an intuitive look at our country’s population through advanced data visualization technology. Situation:

1. The total population of my country continues to grow, with a population of 1.41 billion, still ranking first in the world

In 2020, my country has a total population of 1.41 billion people, accounting for about 18% of the world's total population, and it is still the world's most populous country. In the past ten years, my country’s total population has increased by 72.06 million people, an increase of 5.38% over 2010, with an average annual growth rate of 0.53%.

(The total population of the country continues to grow)

2. The quality of the population has improved, the level of education has improved significantly, and the quality of the population has continued to improve

As shown in the figure, the average number of years of education for people aged 15 and over in my country has increased from 9.08 years in 2010 to 9.91 years. The average number of years of education of the 16-59 working age population increased from 9.67 in 2010 to 10.75 in 2010, and the illiteracy rate dropped from 4.08% in 2010 to 2.67%. The education level of Chinese people has improved, and the quality of the population has been greatly improved.

(The proportion of the educated population in the three provinces is the highest)

3. The gender composition has been improved, and the imbalance between men and women has improved

It can be seen from the chart that the sex ratio of the total population is 105.1, and the ratio of men to women has declined slightly. From the perspective of the birth population, the sex ratio of the birth population is 111.3 in 2020, a decrease of 6.8 compared with 2010, and gradually tends to the normal level.

(Gender ratio tends to be normal)

4. From the perspective of age composition, the proportion of children's population is rising

As shown in the chart, the number of children aged 0-14 has increased by 30.92 million over 2010, an increase of 1.35 percentage points. The “second-child” fertility rate has increased significantly, and the proportion of the “second-child” in the birth population has risen from about 30% in 2013 to about 50% in 2017.

(The aging situation deserves attention)

(The provinces with the highest proportion of children and the elderly are Tibet and Liaoning respectively)

5. Population migration is still active, and the effect of population agglomeration is further manifested

The chart shows that in 2020, the number of separated households in my country will reach 493 million, accounting for about 35% of the total population. Among them, the floating population is 376 million, an increase of nearly 70% in ten years. From the perspective of flow, the population continues to agglomerate along the Yangtze River, coastal areas and inland urban areas. The population of major urban agglomerations such as the Yangtze River Delta, the Pearl River Delta, and the Chengdu-Chongqing urban agglomeration has grown rapidly and the degree of agglomeration has increased.

(Population from the three northeastern provinces mainly flows to the north, Shanghai, Guangzhou and Hainan)

6. From the perspective of urban and rural structure, the urbanization rate of permanent residents has further increased

The permanent population of urban residents increased by 236 million in the past ten years, and the urbanization rate of permanent residents increased by 14.21 percentage points. The results of the census show that the promotion of the urbanization of the agricultural transfer population has achieved remarkable results.

(The proportion of urban population continues to increase)

to sum up

Through these Wyn Enterprise business intelligence software , the data has changed from boring numbers to rich and beautiful images, allowing us to have a clearer and comprehensive understanding of the results of this census. For example, from the chart above, we can find that the major changes in my country’s population in the past ten years reflect the historical process of my country’s economic, social and population development, reflect the practice of promoting high-quality development and decisively building a moderately prosperous society in an all-round way, and are also in line with the population itself. The development trend and the objective law of the interaction between population and economic society. It is believed that in the future, data visualization will gradually penetrate into all walks of life from the government and large enterprises to play a greater value for the construction of "Digital China".
