Data collation

From the aspects of crowd characteristics, total consumption and consumption classification, we can find out a lot of correlations, such as what old women like to buy, how much they generally spend, what young girls like to buy, how much they spend, what adults like, and so on.

In this way, we can draw a conclusion: who generally buys the daily necessities at home, how much they spend, how much their children spend on learning, and who buys more milk and bread, how much. You can get it out regularly.

data analysis

with these analysis data, we can draw some conclusions: men generally don't buy clothes. Who buys daily necessities and rice? There are many grades of oil, and how much most people buy.

How many people buy what students are buying, how much they spend, car decorations and so on, and how many people are buying things related to pets. Then come to a conclusion: what do families or social groups mainly buy? Buying these things shows the quality of life and the income.

Then compare the average income, and you can work out an Engel's coefficient. If you need other analysis, it is to analyze the correlation of goods, which has little to do with the standard of living. For shopping malls and businesses, this is more important.

How many people buy beer and other drinks? Generally, people who buy fruit only buy one or two kinds. With these conclusions, shopping malls will know what the elderly often buy, so the places where these things must be placed should not be too far apart, and whether chewing gum should be placed around these places.

The answer is definitelyno. What young people like, where cosmetics are sold, and whether there are some small toys, all these are related to the merchants.
