By the meaning survey, do you suggest that I put a survey at the particular area for demographic analysis? If you are, do you think the data will be significantly accurate that it will determine the type of customer and crowd?
For your information, I am not those big company. I am just thinking of a small coffee house selling sandwich.
Yes, the data you required are normally done by those big companies who has money to spend on.
That's why there is no data regarding your small business in coffee house selling sandwich, because simply people don't really go to access those survey data for their small business.
All you can do is, you need to go and survey and interview those people at the neighbourhood or school or the park nearby your target business.
