I heard the news recently: my country’s per capita annual income is 30,000 yuan, and 600 million people earn less than 1,000 yuan a month! The shock of this news is no less than the words "China currently has 200 million singles". This news was searched hot for a time, and caused hot discussion on the Internet. Many people don't understand. How could there be so many people earning less than 1,000 yuan, and there are so many people around me who earn more than 10,000 yuan a month... So are there really people who earn more than 10,000 yuan a month?
In order to verify whether this conclusion is correct, I found a set of data on the official website of the National Bureau of Statistics. According to the official data, my country’s per capita disposable income in 2019 is 30,732 yuan, which is an average of 2,561 yuan per month. According to the explanation given on the official website, the residents' disposable income refers to the sum of the residents' final consumption expenditure and savings, that is, the residents' freely disposable income. It includes both cash income and in-kind income. According to the source of income, disposable income includes four items: wage income, net operating income, net property income, and net transfer income. But this sounds too esoteric, so let's give an example.
In fact, it’s easy to understand. Taking a family as an example, we assume that there are five people in a family: husband, wife, grandfather, grandma, and children. In this family, only the husband and wife have income from work, and none of the others have income. There is no other source of income. Assuming that each couple’s salary is 7,500 yuan, then the family’s monthly income is 15,000 yuan, but taxes, five insurances and one housing fund must be deducted. Here, assuming that the amount to be deducted is 2,000 yuan, then there is 13,000 yuan left. , Then the per capita disposable amount in this family is 13,000/5, which is 2,600 yuan. Therefore, the algorithm of the National Bureau of Statistics includes non-labor data. Your monthly salary is not your actual disposable amount. Your income needs to be shared with other people.
To give another example, we usually use averages when calculating per capita wages in companies, which is actually inaccurate, because every company will have employees with high and low wages. If there is one person’s wages Very high, it will increase the overall average, so it cannot reflect the truest wage level. What value should be used to measure it? The most accurate measure is the mode, which is the data with the largest number of people in the salary range. The following figure is an example. If the average is 12,273 yuan, but the largest number is in the range of 5000, 5000 is the best reflection. True level numbers.
So how is this 600 million calculated? According to the data of the National Bureau of Statistics, the lower-middle and low-income people account for 40%. According to the base of our country's population, that is, the population accounts for nearly 600 million! The per capita disposable income in these two ranges is 15,777 and 7,380 yuan respectively. If calculated according to the average value, it is 964 yuan per month, which is less than 1,000 yuan. Although my country’s economic development achievements in the past few years are obvious to all, it is the second largest economy in the world, ranking second only to the United States in GDP, but the cruel fact that per capita disposable income is low, we must see clearly that my country’s per capita income level is comparable to that of developed countries. There is still a very big gap in comparison.
The following is the per capita disposable income of each province in 2019. In order to better display the data, I used the map effect of pwerbi to demonstrate. From the figure, it can be seen that the highest per capita disposable income is mainly concentrated in the eastern coastal cities. The per capita disposable income of the western region is still relatively low, indicating that the gap between the rich and the poor is quite large, so it is not surprising that the per capita disposable income of so many people is low. Due to the geographical disadvantages, the central and western regions have been at a backward level for a long time in history. However, with the vigorous development of my country’s economy, this gap is gradually decreasing. At present, the country is also vigorously promoting the development of the western region. Down to a very low level.
Is Powerbi’s map dashboard cooler? However, the production method is more complicated, and it is not recommended here. There is another way for the map dashboard, which can be implemented with the Smartbi dashboard. The following briefly describes the production process.
The first step: prepare an EXCEL data source:
Step 2: Open the Smartbi Experience Center, select the file to import in the commonly used database, and import the data source:
Step 3: According to the data source you imported, create a new self-service data set, mark the field of region as geographic latitude, and check the "region":
Step 4: Select the graphic component on the toolbar, drag the province and income into the graphic, and select the map in the smart map, then a map dashboard will appear, which will be displayed after the mouse is moved Data for each province:
Step 5: Click the preview on the toolbar, let's take a look at the actual effect, it is very beautiful.
