What is more useful to people data or information why?

Information. Some people think information and data are the same thing, which they aren't. Data are individual facts, like a date of birth. Information is what you get from data by processing it. You could have a list of 100 dates of birth. That is 100 pieces from data. What you might want to know is things like, who is the oldest person, what month has the most birthdays, how many people were born in each year etc. All of those things are information and it is got by processing the data. People collect data in order to get information, so it is information that they really want and what is useful to them.
