Guangzhou is the lowest income among the four first-tier cities. Although it is a first-tier city, it is not much higher than the new first-tier cities like Hangzhou and Nanjing. For routine work, 4K-6K is the most common, while more than 6-8K is specialized, and 8K-12K is also normal for companies with older qualifications or higher unit profit rate. However, it will be difficult to go up to 12K. This figure corresponds to the monthly salary of 15K in Shenzhen. Although it is not small in terms of the number of people, it is still on the low side in terms of proportion. There are two versions of the concept of middle-income group. One is that it exceeds the per capita disposable income of the whole city. For example, in Guangzhou in 2018, the per capita income is 55,000, and the ratio of people with income and those without incom:1, then 55,000 times 1.25 = 68,750, and then divided by 12 months is equal to 5,729 yuan per month, that is, according to the average income, it is 6,000 yuan per month. The other algorithm is based on the median of the population with the highest income of 80% in the city. At present, the highest threshold income of this 80% is about 15,000, which means that 80% of people have a monthly income of less than 15,000, while the current per capita income is 55,000 ÷ 12 = 4,583 yuan, 45,831,500 ≈ 19,500 ব. In other words, the result of the second algorithm is about 10,000 yuan per month, which belongs to middle-income groups. From a practical point of view, the second algorithm is more suitable for first-tier cities like Guangzhou. Of course, this value includes the comprehensive value of wage earners and business people, so it is reasonable to use 10 thousand as the threshold of middle income. If you are a business group alone, you want to reach the middle income level in Guangzhou with a monthly income of at least 50,000.
