How trustworthy is the per capita disposable income of data? In fact, the credibility is very low.

First of all, this data is only voluntary, sample surveys, such as hundreds of people drawn from each city or county. In addition, when you apply for a card, you can also fill in the salary income at will, not to mention the personality of people in each region, for example, some people with an income of 5,000 may fill in 20,000 or 30,000 yuan, and some people only have 100,000 yuan to buy 300,000 cars in order to face the loan. Therefore, the per capita disposable income data cannot measure the true level of wealth of a region.
